[media] s5p-mfc: Don't try to resubmit VP8 bitstream buffer for decode
Currently, for formats that are not H264, MFC driver will check
the consumed stream size returned by the firmware and, based on that,
will try to decide whether the bitstream buffer contained more than
one frame. If the size of the buffer is larger than the consumed
stream, it assumes that there are more frames in the buffer and that the
buffer should be resubmitted for decode. This rarely works though and
actually introduces problems, because:
- v7 firmware will always return consumed stream size equal to whatever
the driver passed to it when running decode (which is the size of the whole
buffer), which means we will never try to resubmit, because the firmware
will always tell us that it consumed all the data we passed to it;
- v6 firmware will return the number of consumed bytes, but will not
include the padding ("stuffing") bytes that are allowed after the frame
in VP8. Since there is no way of figuring out how many of those bytes
follow the frame without getting the frame size from IVF headers (or
somewhere else, but not from the stream itself), the driver tries to guess that
padding size is not larger than 4 bytes, which is not always true;
The only way to make it work is to queue only one frame per buffer from
userspace and the check in the kernel is useless and wrong for VP8.
So adding VP8 also along with H264 to disallow re-submitting of buffer
back to hardware for decode.

[media] s5p-mfc: Copy timestamps only when a frame is produced
Timestamps for destination buffers are assigned by copying them from
corresponding source buffers when the decode operation results in a frame
being outputted to a destination buffer. But the decision when to do this, i.e.
whether the decode operation on current source buffer produced a destination
frame, is wrongly based on "display status". Display status reflects the status
of the destination buffer, not source.
This used to work for firmwares version <= 6, because in addition to the above,
we'd check the decoded frame type register, which was set to "skipped" if
a destination frame was not produced, exiting early from
s5p_mfc_handle_frame_new().
Firmware >=7 does not set the frame type register for frames that were not
decoded anymore though, which results in us wrongly overwriting timestamps of
previously decoded buffers (firmware reports the same destination buffer address
as previously decoded one if a frame wasn't decoded during current operation).
To do it properly, we should be basing our decision to copy the timestamp on the
status of the source buffer, i.e. "decode status". The decode status register
values are confusing, because in its case "display" means "a frame has been
outputted to a destination buffer". We should copy if "decode and display"
is returned in it. This also works on <= v6 firmware, which behaves in the same
way with regards to decode status register.
There are no need to store resource struct and IRQ in the driver
internal structure.
This patch remove these fields and improve error handling by using
proper return codes from devm_ioremap_resource() and devm_request_irq().
[media] mt9p031: Fix BLC configuration restore when disabling test pattern
Auto BLC and BLC digital offset are disabled when enabling the test

the current value. Fix this by writing to the registers directly.
[media] mt9p031: Really disable Black Level Calibration in test pattern mode

gets reenabled by v4l2_ctrl_handler_setup() the next time the device is
powered on.

[media] v4l: ti-vpe: Fix some params in VPE data descriptors
Some parameters of the VPE descriptors were understood incorrectly. They are now
fixed. The fixes are explained as follows:
- When adding an inbound data descriptor to the VPDMA descriptor list, we intend
to use c_rect as the cropped region fetched by VPDMA. Therefore, c_rect->width
shouldn't be used to calculate the line stride, the original image width
should be used for that. We add a 'width' argument which gives the buffer
width in memory.
- frame_width and frame_height describe the complete width and height of the
client to which the channel is connected. If there are multiple channels
fetching data and providing to the same client, the above 2 arguments should
be the width and height of the region covered by all the channels. In the case
where there is only one channel providing pixel data to the client
(like in VPE), frame_width and frame_height should be the cropped width and
cropped height respectively. The calculation of these params is done in the
vpe driver now.
- start_h and start_v is also used in the case of multiple channels to describe
where each channel should start filling pixel data. We don't use this in VPE,
and pass 0s to the vpdma_add_in_dtd() helper.
- Some minor changes are made to the vpdma_add_out_dtd() helper. The c_rect
param is used for specifying the 'composition' target, and 'width' is added
to calculate the line stride.

vpe fops(vpe_open in particular) should be called only when VPDMA firmware

Currently, we register the video device for VPE at driver probe, after calling
a vpdma helper to initialize VPDMA and load firmware. This function is
non-blocking(it calls request_firmware_nowait()), and doesn't ensure that the
firmware is actually loaded when it returns.
We remove the device registration from vpe probe, and move it to a callback
provided by the vpe driver to the vpdma library, through vpdma_create().
The ready field in vpdma_data is no longer needed since we always have firmware
loaded before the device is registered.
A minor problem with this approach is that if the video_register_device
fails(which doesn't really happen), the vpe platform device would be registered.
however, there won't be any v4l2 device corresponding to it.

Pull more cgroup fixes from Tejun Heo:
"Three more patches to fix cgroup_freezer breakage due to the recent
cgroup internal locking changes - an operation cgroup_freezer was
using now requires sleepable context and cgroup_freezer was invoking
that while holding a spin lock. cgroup_freezer was using an overly
elaborate hierarchical locking scheme.
While it's possible to convert the hierarchical spinlocks directly to
mutexes, this patch simplifies the overall locking so that it uses a
global mutex. This has the added benefit of avoiding iterating
potentially huge number of tasks under a spinlock. While the patch is
on the larger side in the devel cycle, the changes made are mostly
straight-forward and the locking logic is a lot simpler afterwards"
