53b5031430 fbdev: sh_mobile_lcdc: Add YUV framebuffer support
Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats
(bpp = 12, 16, and 24) respectively.

When double-buffering both Y planes appear before the C planes (Y-Y-C-C),
as opposed to  Y-C-Y-C.

Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use
.bpp to distiguish between the 3 modes.
The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and
should be set accordingly.
.nonstd must be set to 0 for RGB mode.

Due to the encoding of YUV data, the framebuffer will clear to green
instead of black.

In YUV 420 mode, panning is only possible in 2 line increments.
Additionally in YUV 420 mode the vertical resolution of the framebuffer
must be an even number.

e4fcaeff4f viafb: split pll configs up
This patch splits the pll configs up on pll versions. This allows
easy adding of other known good pll values. Additionally it made it
possible to remove invalid configurations resulting in better
behaviour for such cases. The resulting clocks are no longer stored
resulting in some computing overhead on each mode change.

97597a3977 viafb: always return the best possible clock
Before this patch only clocks that perfectly match were used and if
none existed this was not handled properly. This patch changes this
to always use the closest clock supported. This should behave like
before for clocks that have a perfect match but be much saner for
clocks which are slightly off.

Rather than conditionally compiling out reg_b0_lock, always keep it

e5dedf8d56 VIDEO: cyberpro: add I2C support
Add I2C support for the DDC bus to cyber2000fb driver. This is only bus
support, driver does not use EDID.  Tested on two different CyberPro 2000
cards with i2cdetect and decode-edid.

ac751efa6a console: rename acquire/release_console_sem() to console_lock/unlock()
The -rt patches change the console_semaphore to console_mutex.  As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.

5dc1365cef drivers/video/bf537-lq035.c: Add missing IS_ERR test
lcd_device_register may return ERR_PTR, so a check is added for this value
before the dereference.  All of the other changes reorganize the error
handling code in this function to avoid duplicating all of it in the added
case.

In the original code, in one case, the global variable fb_buffer was set to
NULL in error code that appears after this variable is initialized.  This
is done now in all error handling code that has this property.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier f;
@@
f(...) { ... return ERR_PTR(...); }

@@
identifier r.f, fld;
expression x;
statement S1,S2;
@@
 x = f(...)
 ... when != IS_ERR(x)
(
 if (IS_ERR(x) ||...) S1 else S2
|
*x->fld
)
// </smpl>
