There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.
In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:
- Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
- Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
driver from include/linux/mfd/cros_ec.h to a new file
include/linux/platform_data/cros_ec_proto.h
- Update all the drivers with the new includes, so
- Drivers that only need to know about the protocol include
- linux/platform_data/cros_ec_proto.h
- linux/platform_data/cros_ec_commands.h
- Drivers that need to know about the cros-ec mfd device also include
- linux/mfd/cros_ec.h

On 32-bits archs, a signed integer has 31 bits plus on extra
bit for signal. Due to that, touching the 32th bit with something
like:
int bar = 1 << 31;
has an undefined behavior in C on 32 bit architectures, as it
touches the signal bit. This is warned by cppcheck.
Instead, force the numbers to be unsigned, in order to solve this

There are lots of places where we're doing 1 << 31. That's bad,
as, depending on the architecture, this has an undefined behavior.
The BIT() macro is already prepared to handle this, so, let's
just switch all "1 << number" macros by BIT(number) at the header files
with has 1 << 31.

In case of sensor malfunction, stop streaming timeout takes much longer
than expected. This is due to conversion of time to jiffies: milliseconds
multiplied with HZ (ticks/second) gives out a value of jiffies with 10^3
greater. We need to also divide by 10^3 to obtain the right jiffies value.
In other words FRAME_INTERVAL_MILLI_SEC must be in seconds in order to
multiply by HZ and get the right jiffies value to add to the current
jiffies for the timeout expire time.

This reverts commit b6c61a6c37.
The requested pixelformat is being propagated from the capture to the
tpg in the sensor.
This was a bad design choice, as we start having the following issues:
* We set a pixelformat in the capture;
* We set matching media bus formats in the subdevices pads;
* Link validate looks fine (sizes matches, media bus formats matches);
* Issue: if some of the subdevice doesn't know how to generate the
requested pixelformat in the capture, then stream_on fails. This is bad
because capture says it supports that pixelformat, everything looks
fine, but it is not, and there is no way to find it out through the
links.
This patch was implemented so we could request any pixelformat from the
pipeline regardeless of the media bus format configured between pads.
Not all pixelformat can be mapped into a media bus code (e.g.
multiplanar formats), so with this patch we could request those
pixelformats from the tpg.
Solution: map pixelformats to media bus codes as before, and implement
conversions to other pixelformats in the capture to support multiplanar.
So first step to this solution is to revert this patch.

This patch fixes the following v4l2-compliance failures:

- JPEG colorspace was set instead of SRGB.
- No control events.
- Empty bus_info in QUERYCAP.
- Overlay format handling wasn't zeroing bitmap/clips and
didn't return the chromakey correctly.
- G_FBUF didn't fill in many of the v4l2_framebuffer values.
Now also return the base address of the corresponding
framebuffer that this overlays.
- Missing ENUM/G/S_OUTPUT ioctls.
- ROTATE/VFLIP controls were added when the HW didn't support them.

The OMAP 4 TRM specifies that when using double-index addressing
the address increases by the ES plus the EI value minus 1 within
a frame. When a full frame is transferred, the address increases
by the ES plus the frame index (FI) value minus 1.
The omap-dma code didn't account for the 'minus 1' in the FI register.
To get correct addressing, add 1 to the src_icg value.
This was found when testing a hacked version of the media m2m-deinterlace.c
driver on a Pandaboard.
The only other source that uses this feature is omap_vout_vrfb.c,
and that adds a + 1 when setting the dst_icg. This is a workaround
for the broken omap-dma.c behavior. So remove the workaround at the
same time that we fix omap-dma.c.
I tested the omap_vout driver with a Beagle XM board to check that
the '+ 1' in omap_vout_vrfb.c was indeed a workaround for the omap-dma
bug.
