With this patch, the bq24022 battery charger is controlled by the USB
gadget framework (via gpio_vbus) when connected to USB.
To compile, this patch depends on the "regulator: Allow init data to be
supplied for bq24022" patch (queued for next in the regulator tree) to
add the init_data field to struct bq24022_mach_info.
It also depends on the "add optional OTG transceiver and voltage
regulator support to pda_power" patch (queued for next in the power
supply tree) to enable charging when connected to the AC charger.

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not. There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().
This patch fixes things to pass this string to arch_reset(). This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

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.

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()

dma branching is enabled by extending the current setup_frame_dma()
function to allow a 2nd set of frame/palette dma descriptors to be
used.
As a result, pxafb_dma_buff.dma_desc[], pxafb_dma_buff.pal_desc[]
and pxafb_info.fdadr[] are doubled.
This allows maximum re-use of the current dma setup code, although

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.

Changes made as suggested by Eric Miao (including fix to map_io
silly mistake!).
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

Original patch from Marek Vasut, the problems with PXA26x are:
1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
inverted in GPDR2, as well as their alternate function bits being
'1' for their GPIO functionality in GAFRx
2. there is no easy way to decide if the processor is a pxa26x or a
pxa250/pxa255 at run-time, so the assumption here is the pxa26x
will be treated as one of the pxa25x variants, and board code
should have a better knowledge of the processor it is featured
Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.
Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.
__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.

This reverts commit da1a3dc0eb.
The originally proposed way in the above commit is incorrect. And
there is no easy way to distinguish between pxa25x and pxa26x at
run-time.

Both of these symbols should be defined by a platform, or neither
should be defined. Ensure that all platforms conform.

As Al did for Versatile in 2ad4f86b60,
add a typesafe __io implementation for platforms to use. Convert
platforms to use this new simple typesafe implementation.

Avoid unnecessarily pollution of the kernel's namespace by avoiding
mach/hardware.h. Include this header file where necessary.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing. What
most platforms are using is bus_addr == phys_addr so such is the default.
One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation. Also
added a comment about the special footbridge bus translation.
Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

this patch adds asoc audio driver for pxa27x based Palm PDAs. I tested it for
palmtx, t5 and ld, it should work with palmz72 as well (slapin, please test).
I sent it here some time ago, but now I got to fixing bugs in it. It should
be somehow mostly ok and ready for applying.
[Converted to use snd_soc_dapm_nc_pin() and bool Kconfig -- broonie]

corgi_lcd has symbol conflict with corgi_bl driver.
Fix it by renaming common symbol in new corgi_lcd driver.
