Julia Lawall 1c16697bf9 drivers/video/au*fb.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

In au1100fb.c, the probe function now returns -ENODEV on failure.

Kay Sievers 92a9c19a89 udlfb: remove sysfs framebuffer device with USB .disconnect()
The USB graphics card driver delays the unregistering of the framebuffer
device to a workqueue, which breaks the userspace visible remove uevent
sequence. Recent userspace tools started to support USB graphics card
hotplug out-of-the-box and rely on proper events sent by the kernel.

The framebuffer device is a direct child of the USB interface which is
removed immediately after the USB .disconnect() callback. But the fb device
in /sys stays around until its final cleanup, at a time where all the parent
devices have been removed already.

To work around that, we remove the sysfs fb device directly in the USB
.disconnect() callback and leave only the cleanup of the internal fb
data to the delayed work.

Before:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)

 remove   /2-1.2:1.0/graphics/fb0 (graphics)

After:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)

Manjunathappa, Prakash f820917aba video: da8xx-fb: reset LCDC only if functional clock changes with DVFS
LCDC functional clock may or may not be derived from CPU/MPU DPLL,
For example,
AM335x => Separate independent DPLL for LCDC
Davinci => Same DPLL as MPU

So, on platforms where LCDC functional clock is not derived from CPU/MPU
PLL it is not required to reset LCDC module as its functional clock does
not change with DVFS.

This patch adds check to do reset only if functional clock changes
between pre and post notifier callbacks with DVFS.

Tomi Valkeinen c49d005b6c OMAPDSS: HDMI: PHY burnout fix
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.

This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.

The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.

The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

Tomi Valkeinen 0eaf9f52e9 OMAPDSS: use sync versions of pm_runtime_put
omapdss doesn't work properly on system suspend. The problem seems to be
the fact that omapdss uses pm_runtime_put() functions when turning off
the hardware, and when system suspend is in process only sync versions
are allowed.

Using non-sync versions normally and sync versions when suspending would
need rather ugly hacks to convey the information of
suspending/not-suspending to different functions. Optimally the driver
wouldn't even need to care about this, and the PM layer would handle
syncing when suspend is in process.

This patch changes all omapdss's pm_runtime_put calls to
pm_runtime_put_sync. This fixes the suspend problem, and probably the
performance penalty of always using sync versions is negligible.

Take fifo merge into use by implementing a rather naive fifo merge
threshold calculation: keep the low threshold always the same, but
increase the high threshold when fifo merge is used.

This should greatly increase the time between pixel data fetches from

won't help for fifo underflows, as the low threshols is kept the same.

Tomi Valkeinen 1d71f42b35 OMAPDSS: APPLY: add fifo-merge support
Add fifo-merge support. This is done mainly in four functions:
mgr_enable/disable and ovl_enable/disable. These are the functions where
overlays are taken into and out of active use.

The process to enable and disable fifo-merge is not simple. We need to
do it in steps, waiting in between for certain settings to be taken into
use, and continuing after that. The reason for this is that fifo-merge
is a common thing for all managers/overlays, and its use must be
synchronized.

As an example, when we disable an overlay, we first set the overlay as
disabled, then wait until the overlay is actually disabled in the HW,
and only after that we may re-configure the fifos, possibly taking
fifo-merge into use.

the ovl_mgr_data.

The fifo-merge field is used in the dss_write_regs_common, which handles
writing the register.

Rusty Russell f787f32e67 module_param: make bool parameters really bool (drivers/video/i810)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Jan Beulich 73db144b58 Xen: consolidate and simplify struct xenbus_driver instantiation
The 'name', 'owner', and 'mod_name' members are redundant with the
identically named fields in the 'driver' sub-structure. Rather than
switching each instance to specify these fields explicitly, introduce
a macro to simplify this.

Eliminate further redundancy by allowing the drvname argument to
DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from
the ID table will be used for .driver.name).

Also eliminate the questionable xenbus_register_{back,front}end()
wrappers - their sole remaining purpose was the checking of the
'owner' field, proper setting of which shouldn't be an issue anymore
when the macro gets used.

v2: Restore DRV_NAME for the driver name in xen-pciback.

Mark Brown f4f514734e video: s3c-fb: Take a runtime PM reference when unblanked
When the framebuffer is unblanked hold a runtime PM reference. This
prevents us powering down when userspace has left an image on the
framebuffer and prepares the way for being able to power down the hardware
when an application still has the device open.

Since we now hold a runtime PM reference whenever the display is unblanked
there is no need for the runtime power management to disable and enable
the display, and doing so would lead to runtime PM trying to recurse into
itself when called from the blanking code, so split the runtime PM into
separate functions which only deal with the clocks.  The PM core will
runtime resume the device prior to system suspend.

Mark Brown fe05f8b1c3 video: s3c-fb: Make runtime PM functional again
The change in "video: s3c-fb: modify runtime pm functions" (commit
35784b) renders the runtime power management for the device completely
ineffectual as while it leaves runtime power management notionally
enabled a runtime power reference is held for the entire time the device
is registered meaning it will never actually do anything.

A further issue is introduced as runtime power management is added
during the system suspend path which is not something which drivers are
supposed to do and would interact poorly if there were any operations
done in the runtime power management callbacks.

While this does make things simpler (the main motivation for the
original change) it will not only cause us to use more power in the
framebuffer controller but will also prevent us entering lower power
domain and SoC wide states as we can never power down the domain
containing the device.  Since neither of these things is desirable
revert the change.

Benjamin Herrenschmidt 1bb0b7d215 offb: Fix setting of the pseudo-palette for >8bpp
When using a >8bpp framebuffer, offb advertises truecolor, not directcolor,
and doesn't touch the color map even if it has a corresponding access method
for the real hardware.

Thus it needs to set the pseudo-palette with all 3 components of the color,
like other truecolor framebuffers, not with copies of the color index like
a directcolor framebuffer would do.

This went unnoticed for a long time because it's pretty hard to get offb
to kick in with anything but 8bpp (old BootX under MacOS will do that and
qemu does it).

Benjamin Herrenschmidt 9b961ed21a offb: Add palette hack for qemu "standard vga" framebuffer
We rename the mach64 hack to "simple" since that's also applicable
to anything using VGA-style DAC IO ports (set to 8-bit DAC) and we
use it for qemu vga.

Note that this is keyed on a device-tree "compatible" property that
is currently only set by an upcoming version of SLOF when using the
qemu "pseries" platform. This is on purpose as other qemu ppc platforms
using OpenBIOS aren't properly setting the DAC to 8-bit at the time of
the writing of this patch.

We can fix OpenBIOS later to do that and add the required property, in
which case it will be matched by this change.

Chandrabhanu Mahapatra 7282f1b7c9 OMAPDSS: DISPC: Update Scaling Clock Logic
Clock requirements for scaling in OMAP2, OMAP3 and OMAP4 are different. In
OMAP2 and OMAP3 the required clock rate is a function of pixel clock, vertical
downscale ratio and horizontal downscale ratio whereas in OMAP4 it is a
function of pixel clock and horizontal downscale ratio only. Selection of 3-tap
vs 5-tap coefficients depends on clock rate line buffer width in OMAP3 whereas
in OMAP4 it is independent of clock rate and line buffer width. In OMAP2 3-tap
for vertical and 5-tap for horizontal scaling is used. In OMAP4 5-tap is used
both for horizontal and vertical scaling for better performance. Also, the
number and width of line buffers differs in OMAP3 and OMAP4.

So, clock functions have been fined tuned for OMAP3 and support has been added
added for OMAP4. This code has been tested on OMAP2, OMAP3 and OMAP4, and
scaling issues due to clock errors have been resolved.

Chandrabhanu Mahapatra debd90749b OMAPDSS: DISPC: Update Fir Coefficients
The FIR coefficients present in kernel are being updated to new coefficients
consisting of 24 coefficient tables, with 12 each for 3 tap and 5 tap scenario,
which are chosen on the basis of DISPC up/downsampling filters M value. M is
the inverse of low pass cut off frequency of the sampling filter. For vertical
scaling 3 tap or 5 tap tables are used based on the clock rate and width of
the line buffer whereas in OMAP2 3 tap is always used. For horizontal scaling
however 5 tap tables are always used.

New coefficients and the corresponding logic have been tested on OMAP2, OMAP3
and OMAP4. Horizontal and vertical scaling worked fine except for some 3 tap
vs 5 tap issue during vertical upscaling and clock failing issues which is
acknowledged in the next patch. Vertical upscaling was found to perform better
under 5 taps. The 24 coefficient tables have been moved to another file
dispc_coefs.c for proper maintainance.

This code is written based on code written by Lajos Molnar <lajos@ti.com> in
Android Kernel for scaling. Lajos Molnar <lajos@ti.com> had fine tuned the FIR
coefficient selection process and reduced outliness and blockiness around
images when upscaling more than 2 times.

Runtime suspend and runtime resume are modified in order to
reduce the complexity and improve the usability of runtime pm.
After probe function, s3c-fb driver is not suspended until
suspend or remove is called.

The scheme is changed as follows:
 runtime_get is only called in probe and resume.
 runtime_put is only called in remove and suspend.
 open/close cannot call the runtime_get/put.

Also, runtime_susepnd/resume are just called by runtime pm,
not doing suspend/resume routine any longer. This is because
open/close cannot call the runtime_get/put; the suspend/resume
routine in runtime_suspend/resume were previously used when
open and close were called.

The name of s3c-fb dev_pm_ops is changed from s3cfb_pm_ops to

Timur Tabi ddd3d90543 drivers/video: fsl-diu-fb: merge all allocated data into one block
The Freescale DIU driver allocates multiple blocks of memory, including
multiple DMA buffers.  Merge all of these blocks into one data structure.

Specifically:

1) struct fsl_diu_data now contains everything that needs to be allocated,
except for the framebuffers themselves.  DMA'able objects are aligned correctly
within the structure.

2) struct diu_addr is no longer needed, because we don't have to manage
multiple blocks of DMA memory.

3) Since there's no diu_addr any more, macro DMA_ADDR is used to calculate
the DMA address of any field in fsl_diu_data.

4) Functions allocate_buf() and free_buf() are no longer needed, because we
now assume that dma_alloc_coherent() will allocate a page-aligned block,
and everything is properly aligned with fsl_diu_data already, so we no longer
need to align any memory blocks ourselves.

5) The "dummy" area descriptor is now defined separately from the other
five ADs, so NUM_AOIS (previously called FSL_AOI_NUM) is now set to five
instead of six.  Previously, all six were combined together to avoid a
separate call to allocate_buf() just for the dummy AD.

6) framebuffer_alloc() and framebuffer_release() are no longer used.  The
framebuffer is initialized manually.

7) Error handling is simplified since there's only one memory buffer
allocated.

Sascha Hauer f910fb8fcd video i.MX IPU: Fix display connections
The IPU internally works on 32bit colors. It can arbitrarily map
between pixel formats and internal representation and also between
internal representation and the physical connection to the display.
The driver used to change the mapping between internal representation
and display connection depending on the user selected bpp which is
wrong. Instead, the mapping is specified by the hardware, so an
additional field in platform data is added to describe the connection
between i.MX and the display. The default for this field is RGB666
which seems to be the only configuration which works without this
patch, so I assumed that all in Kernel boards are connected this
way.
This patch has been tested on a RGB666 connected display and a
RGB888 connected display in both 16bpp and 32bpp modes.

In the apply irq handler the code currently clears the shadow dirty
flags whenever the manager in question is not busy (i.e. GO bit is
down). However, this is not quite right, as the GO bit may have never
been set.

While not done in the current code, the above would cause bug in
scenario where the registers are written, and thus shadow_dirty flag is
set, but the GO bit will be set only later. In this case the
shadow_dirty flags would be cleared, even if the HW is not using the new
configurations.

This patch fixes the issue by clearing the shadow flags only when the GO
bit is clear, and the GO bit had been set.

Note that the function returns always 0 for DIGIT channel, even if OMAP4

FRAMEDONE_TV is not needed.

If there's need in the future to also get the FRAMEDONE_TV this needs
revisiting. However, as FRAMEDONE_TV doesn't exist on OMAP2/3, the use
of this function for that purpose needs some extra code to handle the

Two helper functions are added: need_isr(), which returns if an isr for
VSYNC is needed, and need_go(), which tells if there has been a write to
the shadow registers and we need to set the GO bit.

The functions that call the actual dispc write functions will set the

the caller side. The writing functions also check if the dirty flag is
even set, and return immediately if not.

Tomi Valkeinen aaa874a985 OMAPDSS: APPLY: rewrite overlay enable/disable
Overlays are currently enabled and disabled with a boolean in the struct
omap_overlay_info. The overlay info is set with ovl->set_overlay_info(),
and made into use with mgr->apply().

This doesn't work properly, as the enable/disable status may affect also
other overlays, for example when using fifo-merge. Thus the enabling and
disabling of the overlay needs to be done outside the normal overlay
configuration.

This patch achieves that by doing the following things:

1) Add function pointers to struct omap_overlay: enable(), disable() and
is_enabled(). These are used to do the obvious. The functions may block.

2) Move the "enabled" field from struct omap_overlay to ovl_priv_data.

3) Add a new route for settings to be applied to the HW, called
"extra_info". The status of the normal info and extra_info are tracked
separately.

The point here is to allow the normal info to be changed and
applied in non-blocking matter, whereas the extra_info can only be
changed when holding the mutex. This makes it possible to, for example,
set the overlay enable flag, apply it, and wait until the HW has taken
the flag into use.

This is not possible if the enable flag would be in the normal info, as
a new value for the flag could be set at any time from the users of
omapdss.

Tomi Valkeinen 9a147a65de OMAPDSS: DSI: call mgr_enable/disable for cmd mode displays
The current code uses dsi_video_mode_enable/disable functions to
enable/disable DISPC output for video mode displays. For command mode
displays we have no notion in the DISPC side of whether the panel is
enabled, except when a dss_mgr_start_update() call is made.

However, to properly maintain the DISPC state in apply.c, we need to
know if a manager used for a manual update display is currently in use.

This patch achieves that by changing dsi_video_mode_enable/disable to
dsi_enable/disable_video_output, which is called by both video and
command mode displays. For video mode displays it starts the actual
pixel stream, as it did before. For command mode displays it doesn't do
anything else than mark that the manager is currently in use.

The functions in apply.c, called mostly via function pointers in overlay
and overlay_manager structs, will be divided into two groups. The other

The idea is that the non-sleeping functions may only change certain
settings in overlays and managers, and those settings may only affect
the particular overlay/manager. For example, set the base address of the
overlay.

The blocking functions, however, will handle more complex configuration
changes. For example, when an overlay is enabled and fifo-merge feature
is used, we need to do the enable in multiple steps, waiting in between,
and the change affects multiple overlays and managers.

apply.c already contains a spinlock, which has been used to protect

ovl_setup() to convert those zero values to width or height.

This patch makes ovl_setup() accept zero values for out_width/height,
making calling ovl_setup() a bit simpler as the overlay_info can be
just passed to this function without modifications.

Tomi Valkeinen 6331709bca OMAPDSS: remove partial update from panel-taal
Partial update for manual update displays has never worked quite well:
* The HW has limitations on the update area, and the x and width need to
  be even.
* Showing a part of a scaled overlay causes artifacts.
* Makes the management of dispc very complex

Considering the above points and the fact that partial update is not
used anywhere, this and the following patches remove the partial update
support. This will greatly simplify the following re-write of the apply
mechanism to get proper locking and additional features like fifo-merge.

This patch removes the partial update from the panel-taal.c.

Tomi Valkeinen 3b98409eb7 OMAPDSS: DSI: improve wait_for_bit_change
We sometimes get timeout when disabling the DSI interface with video
mode. It looks like the disable will stall until the current frame has
been finished, and this can take multiple milliseconds.

wait_for_bit_change() currently uses a busyloop to wait for a bit to
change. This is used in multiple places. The problem is, we don't have
clear understanding how long particular operations can take, so the
function needs to support longer waits.

Improve wait_for_bit_change() to first busy loop for 100 times to see if
the bit changes almost right away. If the bit hasn't changed, move to a
loop with a sleep of 1ms, and poll for 500ms.

Rob Clark cd5351f4d2 staging: add omapdrm DRM/KMS driver for TI OMAP platforms
A DRM display driver for TI OMAP platform.  Similar to omapfb (fbdev)
and omap_vout (v4l2 display) drivers in the past, this driver uses the
DSS2 driver to access the display hardware, including support for
HDMI, DVI, and various types of LCD panels.  And it implements GEM
support for buffer allocation (for KMS as well as offscreen buffers
used by the xf86-video-omap userspace xorg driver).

The driver maps CRTCs to overlays, encoders to overlay-managers, and
connectors to dssdev's.  Note that this arrangement might change slightly
when support for drm_plane overlays is added.

For GEM support, non-scanout buffers are using the shmem backed pages
provided by GEM core (In drm_gem_object_init()).  In the case of scanout
buffers, which need to be physically contiguous, those are allocated
with CMA and use drm_gem_private_object_init().

See userspace xorg driver:
git://github.com/robclark/xf86-video-omap.git

Refer to this link for CMA (Continuous Memory Allocator):
http://lkml.org/lkml/2011/8/19/302

History:

v5: move headers from include/drm at Greg KH's request, minor rebasing
    on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages()
    because "drm/gem: add functions to get/put pages" patch is not
    merged yet
v4: bit of rework of encoder/connector _dpms() code, modeset_init()
    rework to not use nested functions, update TODO.txt
v3: minor cleanups, improved error handling for dev_load(), some minor
    API changes that will be needed later for tiled buffer support
v2: replace omap_vram with CMA for scanout buffer allocation, remove
    unneeded functions, use dma_addr_t for physical addresses, error
    handling cleanup, refactor attach/detach pages into common drm
    functions, split non-userspace-facing API into omap_priv.h, remove
    plugin API

Tomi Valkeinen f95cb5ebd8 OMAPDSS: DISPC: skip scaling calculations when not scaling
Current code calculates scaling factors for video overlays even when the
overlays are not scaled. Change the code to skip calculations when not
scaling.

This optimizes the code a bit, but also fixes a problem when configuring
an overlay for a disabled display: if the display is disabled we don't
necessarily know the pixel clock used when the display is enabled, and
in some cases (like HDMI) the pixel clock is set to zero until a proper
video mode is set later. A wrong pixel clock will mess up the
scaling calculations, causing an error like:

omapdss DISPC error: failed to set up scaling, required fclk rate = 0
Hz, current fclk rate = 170666666 Hz

A proper fix would be to check later whether the clocks are enough for the
scaling, at the point when the overlay or display is actually enabled,
but this patch removes the problem for now.

Tomi Valkeinen ef319c6e09 OMAPDSS: HDMI: fix returned HDMI pixel clock
hdmi_get_pixel_clock() returns the pixel clock in Hz, but the pck is
stored as kHz. This means the return value has to be multiplied by 1000,
not by 10000 as the code did.
