The driver's fb_mmap function is essentially the same as a generic fb_mmap
function. Delete driver's function and use the generic one.
A difference is that generic function marks frame buffer memory as VM_IO |
VM_RESERVED. The driver's function marks it as VM_IO only.

Add support for the ARGB1888 and ARGB4888 hardware to the Samsung SoC
Framebuffer driver (s3c-fb.c).
ARGB1888 and ARGB4888 is decided by var->transp.length and this variable
is set by s3c_fb_check_var().
In s3c_fb_check_var(), if var->vits_per_pixel is 25 or 28, then
var->transp.length would be 1 or 3.
Therefore alpha mode(ARGB1888 or ARGB4888) could be decided through that
variable.
For using alpha mode, you need to set the following: This code should be
added to your machine code as platform data.
static struct s3c_fb_pd_win xxx_fb_win0 = {
/* this is to ensure we use win0 */
.win_mode = {
.pixclock = (8+8+8+240)*(38+4+38+400),
.left_margin = 8,
.right_margin = 8,
.upper_margin = 38,
.lower_margin = 38,
.hsync_len = 8,
.vsync_len = 4,
.xres = 240,
.yres = 400,
},
.max_bpp = 32,
.default_bpp = 24,
};
static struct s3c_fb_pd_win xxx_fb_win1 = {
.win_mode = {
.pixclock = (8+8+8+240)*(38+4+38+400),
.left_margin = 8,
.right_margin = 8,
.upper_margin = 38,
.lower_margin = 38,
.hsync_len = 8,
.vsync_len = 4,
.xres = 240,
.yres = 400,
},
.max_bpp = 32,
.default_bpp = 28,
};
static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
.win[0] = &ncp_fb_win0,
.win[1] = &ncp_fb_win1,
.vidcon0 = VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
.vidcon1 = VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC,
.setup_gpio = xxx_fb_gpio_setup,
};
s3c_fb_set_platdata(&xxx_lcd_pdata);
The above code sets pixelformat for window0 layer to RGB888 and window1
layer to ARGB4888.

AFAICT the code which checks that the requested pixclock value is within
bounds is incorrect. It ensures that the lcdc core clock is at least
(bytes per pixel) times higher than the pixel clock rather than just
greater than or equal to.
There are tighter restrictions on the pixclock value as a function of bus
width for STN panels but even then it isn't a simple relationship as
currently checked for. IMO either something like the below patch should
be applied or else more detailed checking logic should be implemented
which takes in to account the panel type as well.

The LIS302DL accelerometer chip has a 'click' feature which can be used to
detect sudden motion on any of the three axis. Configuration data is
passed via spi platform_data and no action is taken if that's not
specified, so it won't harm any existing platform.
To make the configuration effective, the IRQ lines need to be set up
appropriately. This patch also adds a way to do that from board support
code.
The DD_* definitions were factored out to an own enum because they are
specific to LIS3LV02D devices.

After measurement on my laptop, it seems that turning off the device does
not bring any energy saving (within 0.1W precision). So let's keep the
device always on. It simplifies the code, and it avoids the problem of
reading a wrong value sometimes just after turning the device on.
Moreover, since commit ef2cfc790b had been
too zealous, the device was actually never turned off anyway. This patch
also restores the damages done by this commit concerning the
initialisation/poweroff.

The console blank timer is currently hardcoded to 10*60 seconds which
might be annoying on systems with no input devices attached to wake up the
console again. Especially during development, disabling the screen saver
can be handy - for example when debugging the root fs mount mechanism or
other scenarios where no userspace program could be started to do that at
runtime from userspace.
This patch defines a core_param for the variable in charge which allows
users to entirely disable the blank feature at boot time by setting it 0.
The value can still be overwritten at runtime using the standard ioctl
call - this just allows to conditionally change the default.

Since videobuf-dma-contig is designed to handle physically contiguous
memory, this patch modifies the videobuf-dma-contig code to only accept a
user space pointer to physically contiguous memory. For now only
VM_PFNMAP vmas are supported, so forget hotplug.
On SuperH Mobile we use this with our sh_mobile_ceu_camera driver together
with various multimedia accelerator blocks that are exported to user space
using UIO. The UIO kernel code exports physically contiguous memory to
user space and lets the user space application mmap() this memory and pass
a pointer using the USERPTR interface for V4L2 zero copy operation.
With this approach we support zero copy capture, hardware scaling and
various forms of hardware encoding and decoding.

PIT_TICK_RATE is currently defined in four architectures, but in three
different places. While linux/timex.h is not the perfect place for it, it
is still a reasonable replacement for those drivers that traditionally use
asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency.
Note that for Alpha, the actual value changed from 1193182UL to 1193180UL.
This is unlikely to make a difference, and probably can only improve
accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE
a few years ago, after which every existing instance was getting changed
to 1193182. According to the specification, it should be
1193181.818181...

This patch changes cx88_set_stereo to avoid resetting all of the audio
registers on stereo/mono change if the audio standard is A2, and set
only the AUD_CTL register. The benefit of this method is that it
eliminates the annoying clicking noise on setting the audio mode to
stereo or mono.
The driver had used the same method 1.5 years ago (and for FM radio it
still does), but a pretty big cleanup commit changed it to the
"complete audio reset" method, although the reason for this move was
not clear. (If somebody knows why it was necessary, please let me
know!)

The sole purpose of the audio thread is to detect if stereo transmission is
available, and if it is, then switch to stereo mode (and switch back, if it's
no longer available). This manual autodetection is useful for some audio
standards (e.g. A2) where cx88_get_stereo CAN detect stereo sound, but the
cx2388x chip CANNOT auto-detect stereo sound.
However, for other audio standards, the cx2388x chip CAN auto-detect the stereo
sound, so the manual autodetection in the audio thread is not needed. In fact,
it can cause serious problems because for some of these audio standards,
cx88_get_stereo CANNOT detect the presence of stereo sound. Besides that, if
the hardware automatically detects stereo/mono sound, you cannot set
core->audiomode_current to the real current audio mode on channel change.
With this patch, the manual autodetection is only used if audiomode_current is
known after a channel change (because of the initial mono mode), and
hardware-based stereo autodetecion is not applicable for the current audio
standard.

The patch implements reliable stereo and sap detection for the A2 sound
standard. This is achieved by processing the samples of the audio RDS fifo of
the cx2388x chip. A2M, EIAJ and BTSC stereo/sap detection is also possible with
this new approach, but it's not implemented yet. Stereo detection when alsa
handles the sound also does not work yet.

The fact that we now explicitly set fepriv->exit = 1 when the thread is
shutting down exposed an edge case where it was not being reset back to zero
once the thread went away in some cases. This resulted in failures in cases
where the frontend was closed, and then opened O_RDONLY, since in that case
the thread is not being restarted but it was checking the fepriv->exit flag.
Thanks to Thierry Lelegard, who and encountered and debugged a large portion
of the issue in the same twelve hours that I did (as well as testing my patch).

A race condition was detected in the case that putting the tuner to sleep takes
an unusually long period of time, combined with applications that quickly
close/open the dvb frontend.
The kaffeine channel scanner closes and reopens the dvb frontend between each
tuning attempt. If it takes an unusually longer period of time to put the
tuner to sleep (for example, the Pinnacle 801e takes 660 ms), the dvb_frontend
thread will still be in a running state (and hence fepriv->thread is still set)
but the fepriv->exit field will still be zero. As a result, if a
dvb_frontend_start() call arrives while the frontend thread is in the process
of terminating, the call will return 0 without actually starting a new thread.
This results in the tuning request being dropped.
To address this, mark fepriv->exit as soon as we know the thread is going to
be terminated, so that dvb_frontend_start() knows to start a new instance.
Problem encountered with Kaffeine 0.8.7 doing ATSC scanning against the
Pinnacle 801e tuner, in conjunction with new code to power down the xc5000
when not in use.

A power management fix to properly put the xc5000 into low power mode
revealed a race condition where hald could detect the creation of the device
file and connect to the device while the initial device configuration is
still in progress.
Lock the core structure so that video_release cannot be called and put the
tuner to sleep in the middle of the initial call to cx88_set_tvnorm() in
cx8800_initdev()
