[ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devices
PXA27x and later processors support overlay1 and overlay2 on-top of the
base framebuffer (although under-neath the base is also possible). They
support palette and no-palette RGB formats, as well as YUV formats (only
available on overlay2). These overlays have dedicated DMA channels and
behave in a similar way as a framebuffer.
This heavily simplified and re-structured work is based on the original
pxafb_overlay.c (which is pending for mainline merge for a long time).
The major problems with this pxafb_overlay.c are (if you are interested
in the history):
1. heavily redundant (the control logics for overlay1 and overlay2 are
actually identical except for some small operations, which are now
abstracted into a 'pxafb_layer_ops' structure)
2. a lot of useless and un-tested code (two workarounds which are now
fixed on mature silicons)
3. cursorfb is actually useless, hardware cursor should not be used
this way, and the code was actually un-tested for a long time.
The code in this patch should be self-explanatory, I tried to add minimum
comments. As said, this is basically simplified, there are several things
still on the pending list:
1. palette mode is un-supported and un-tested (although re-using the
palette code of the base framebuffer is actually very easy now with
previous clean-up patches)
2. fb_pan_display for overlay(s) is un-supported
3. the base framebuffer can actually be abstracted by 'pxafb_layer' as
well, which will help further re-use of the code and keep a better
and consistent structure. (This is the reason I named it 'pxafb_layer'
instead of 'pxafb_overlay' or something alike)
See Documentation/fb/pxafb.txt for additional usage information.

[ARM] pxafb: cleanup of the color format manipulation code
1. introduce var_to_depth() to calculate the color depth including the
transparency bit
2. the conversion from 'fb_var_screeninfo' to LCCR3 BPP bits can be re-
used by overlays (in OVLxC1), thus an individual pxafb_var_to_bpp()
has been separated out.
3. pxafb_setmode() should really set the color bitfields correctly at
begining, introduce a pxafb_set_pixfmt() for this
4. allow user apps to specify color formats within fb_var_screeninfo,
and checking of this in pxafb_check_var() has been simplified as
below:
a) pxafb_var_to_bpp() should pass - which means a basically correct
bits_per_pixel and color depth setting
b) the RGBT bitfields are then forced into supported values by
pxafb_set_pixfmt()

Note the var->yres_virtual is only re-calculated from the fix.smem_len
when text mode acceleration is enabled (which is default), this is due
to the issue as Russell suggested below:
Previous experience of doing this with the X server and acornfb is that
it causes all sorts of problems - it seems to force the X server into
assuming that the framebuffer should be panned no matter what settings
you ask it for.
The recommended workaround (implemented in acornfb) is to only do these
kinds of adjustments if text mode acceleration is enabled. IIRC, the X
server should be disabling text mode acceleration when it maps the
framebuffer. I seem to remember that there are X servers which forget
to do that though.

[ARM] pxafb: allow video memory size to be configurable
The amount of video memory size is decided according to the following
order:
1. <xres> x <yres> x <bits_per_pixel> by default, which is the backward
compatible way
2. size specified in platform data
3. size specified in module parameter 'options' string or specified in
kernel boot command line (see updated Documentation/fb/pxafb.txt)
And now since the memory is allocated from system memory, the pxafb_mmap
can be removed and the default fb_mmap() should be working all right.
Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA
descriptors and palettes, the allocation can be separated cleanly.
NOTE: the LCD DMA actually supports chained transfer (i.e. page-based
transfers), to simplify the logic and keep the performance (with less
TLB misses when accessing from memory mapped user space), the memory
is allocated by alloc_pages_*() to ensures it's physical contiguous.

When CONFIG_PM is selected, the VFP code does not have any handler

resume.
On resume, the VFP will have been reset and the co-processor access
control registers are in an indeterminate state (very probably the
CP10 and CP11 the VFP uses will have been disabled by the ARM core
reset). When this happens, resume will break as soon as it tries to
unfreeze the tasks and restart scheduling.
Add a sys device to allow us to hook the suspend call to save the
current thread state if the thread is using VFP and a resume hook
which restores the CP10/CP11 access and ensures the VFP is disabled
so that the lazy swapping will take place on next access.

Originally designed by Intel, now sold by Crossbow (www.xbow.com).
Very little actually on board. The patch includes sensors and
similar as found on commonly occurring daughter boards.
Some of the drivers are not in mainline as yet as they are either
part of the IIO subsystem or need a lot of work before submission.
What is the position wrt to putting them in i2c board configs etc?
Support for these boards has been maintained outside the kernel
for a long time, but now that there is a good da9030 pmic driver
available the last major hurdle no longer exists.
All comments welcomed.
The Imote2's big brother (stargate2) will follow once any problems
with this one have been cleaned up and a few bits and bobs have
been added to the da903x driver. Hopefully the cc2420 driver will
get cleaned up and submitted in the not too distant future as
well.

[ARM] pxafb: allow insertion of delay to the smart panel command sequence
Some smart panel requires a delay between command sequences, while PXA
LCD controller didn't provide such one, let's emulate this by software.
A software delay marker can be inserted into the command sequence, once
pxafb_smart_queue() detects this, it flushes the previous commands and
delay for a specified number of milliseconds.

[ARM] pxafb: allow better platform configurable smart panel timing
For smart panels (LCD panel with internal framebuffer), the following
LCCR3 register bits have different meanings than the parallel one:
LCCR3_PCP - controls the L_PCLK_WR polarity
LCCR3_HSP - controls the L_LCLK_A0 polarity
LCCR3_VSP - controls the L_FCLK_RD polarity
To keep minimum change to the original parallel timing, the .lcd_conn
flags and 'pxafb_mode_info.sync' are re-used to reflect this:
LCD_PCLK_EDGE_{RISE,FALL} - configures LCCR3_PCP
sync & FB_SYNC_{HOR,VERT}_HIGH_ACT - configures LCCR3_{HSP,VSP}
