Russell King 3e68439bf0 imx-drm: imx-drm-core: add core hotplug connector support
Add core imx-drm support for hotplug connector support.  We need to
setup the poll helper after we've setup the connectors; the helper
scans the connectors to determine their capabilities.

Russell King b85f2b5d87 imx-drm: imx-drm-core: move allocation of imxdrm device to driver load function
It is now no longer necessary to keep this structure around; we can

Russell King 06c6b82bf7 imx-drm: imx-drm-core: get rid of drm_mode_group_init_legacy_group()
Since we're now operating like a conventional DRM driver, doing all
the initialisation within the driver's ->load callback, we don't
need to mess around with the mode groups - we can rely on the one
in the DRM platform code.

Russell King 1b3f767566 imx-drm: initialise drm components directly
Now that our bind function is only ever called during the main DRM
driver ->load callback, we don't need to have the imx_drm_connector or
imx_drm_encoder abstractions anymore.  So let's get rid of it, and move
the DRM connector and encoder setup into the connector support files.

Russell King 32266b4520 imx-drm: use supplied drm_device where possible
The component helper provides us the drm_device which is being
registered.  Rather than having to reference a global in imx-drm-core,
use this to get the imxdrm device, and also use it to register the CRTC
against.

This means we never have CRTCs/encoders/connectors without the drivers
private data being accessible.

Remove the module owner field as well; this provides no protection
against the device being unbound.

Russell King 8acba02f7e imx-drm: remove separate imx-fbdev
Now that we know when the components of the imx-drm subsystem will be
initialised, we can move the fbdev helper initialisation and teardown
into imx-drm-core.  This gives us the required ordering that DRM wants
in both driver load and unload methods.

We can also stop exporting the imx_drm_device_get() and
imx_drm_device_put() methods; nothing but the fbdev helper was making
use of these.

Delay publishing sysfs connector entries until all components have

events when we're uncertain whether the driver can fully initialise.
This also pulls that code out of the individual imx-drm connector

Russell King f2d66aad1a imx-drm: simplify setup of panel format
The encoder format passed into imx_drm_crtc_panel_format*() is the
encoder format used for DRM in most cases; the HDMI encoder sets
this to none, but this is incorrect, it should be TMDS.

Since this is the case, we can pass the drm_encoder structure
directly into this function and use the supplied fields there to
configure the CRTC.

Russell King e76171b046 imx-drm: imx-drm-core: sanitise imx_drm_encoder_get_mux_id()
Address the following issues:
- imx_drm_encoder_get_mux_id() searches the CRTC list for the matching
  CRTC, and returns the position within this list as the MUX programming
  value for encoders.  This is sub-optimal for two reasons:
  1. It relies upon the CRTC list not changing during the lifetime of
     the driver.
  2. It is dependent on the initialisation order of the CRTCs.

  We address (1) in this patch, leaving (2) until a better solution can
  be found, as (2) requires larger changes.

- imx_drm_encoder is unused.  Instead, pass the drm_encoder which is
  slightly more useful; all callers pass encoder->crtc as the required
  crtc, so move this inside the function.

Russell King 24013ea8ff imx-drm: ipu-v3: more inteligent DI clock selection
The DI clock selection was very rudimentary: it would statically use
either the IPU internal clock or the DI external clock depending on
which "encoder" was being used.  In the case of HDMI, it would always
use the IPU clock.

Moreover, using the IPU clock resulted in fractional divisors, which
are achieved by skipping clock pulses.  This can result in the HDMI
PHY PLL being frequency modulated, and the attached device is then
unable to properly lock on to the TMDS clock.

We need at least 1% accurate and stable clocks for HDMI.

Arrange for the DI clock to be sourced from the IPU internal clock
if it can satisfy our requirements, otherwise switch to the DI
external clock and try and set the external clock to our desired
pixel clock rate.

wasn't being adjusted at all when the display mode is modified.

Get rid of the seaprate 'pixel_clk_rate', and use the stored pixel
clock rate instead.  Pass this desired pixel clock rate into
hdmi_set_clk_regenerator().  Collapse down hdmi_init_clk_regenerator()
since it is a copy of hdmi_set_clk_regenerator(), and pass a default
pixel clock rate.

Greg Kroah-Hartman 5c0a2450d6 Revert "tty: Set correct tty name in 'active' sysfs attribute"
This reverts commit d8a5dc3033.

This breaks plymouth installs, either because plymouth is using the file
"incorrectly" or because the patch is incorrect.  Either way, this needs
to be reverted until it is all figured out.

Result was a probe fail after successful parsing the DTS:

Linus Torvalds 10527106ab Device tree compatible match order bug fix
This branch contains a bug fix for the way devicetree code identifies
 the type of device. Device drivers can contain a list of of_device_ids,
 but it more than one entry will match, then the device driver may choose
 the wrong one. Commit 105353145e, "match each node compatible against
 all given matches first", was queued for v3.14 but ended up causing
 other bugs. Commit 06b29e76a7 attempted to fix it but it had other bugs.
 Merely reverting the fix and waiting until v3.15 isn't a good option
 because there is code in v3.14 that depends on the revised behaviour to
 boot.
 
 This branch should finally fixes the problem correctly. This time
 instead of just hoping that the patch is correct, this branch also adds
 new testcases that validate the behaviour.
 
 The changes in this branch are larger than I would like for a -rc pull,
 but moving the test case data out of out of arch/arm so that it could be
 validated on other architectures was important.

Linus Torvalds 7777d93489 IOMMU Fixes for Linux v3.14-rc3
The fixes are only for the ARM-SMMU driver. Here is the summary from
 Will Deacon:
 
   - Andreas Herrmann took the driver for a run with a real SATA
     controller, which caused the new mutex-based locking to explode
     since we require mappings in atomic context
 
   - Yifan fixed an issue with the page table creation, which then caused
     breakages with the way in which we flush descriptors out to the
     table walker
 
   - I ran the driver on a system where the SMMU is hooked into a
     coherent interconnect for table walks, and noticed a shareability
     mismatch between the CPU and the SMMU
 
 These issues are all fixed here and have been tested on both arm and
 arm64 based systems.
 
 Besides that I put a fix on-top to make the spinlock irq-safe, so that the
 code-paths can be used in the DMA-API.

Linus Torvalds 0413320900 sound fixes for 3.14-rc4
This time we got a slightly higher volume than previous times,
 but all device-specific good fixes.  Noticeable changes are fixes in
 davinci, and the removal of open-codes in HD-audio ca0132 driver.
 The rest are all small fixes and/or quirks.
