[ Upstream commit f3775f89852d167990b0d718587774cf00d22ac2 ]
coda_encoder_cmd() is racy, as the last scheduled picture run worker can
still be in-flight while the ENC_CMD_STOP command is issued. Depending
on the exact timing the sequence numbers might already be changed, but
the last buffer might not have been put on the destination queue yet.
In this case the current implementation would prematurely wake the
destination queue with last_buffer_dequeued=true, causing userspace to
call streamoff before the last buffer is handled.
Close this race window by synchronizing with the pic_run_worker before
doing the sequence check.

[ Upstream commit 75fa6e4f83a0923fe753827d354998d448b4fd6a ]
Add support for the third loop filter mode
V4L2_MPEG_VIDEO_H264_LOOP_FILTER_MODE_DISABLED_AT_SLICE_BOUNDARY,
and fix V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA and
V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_BETA controls.
The filter offset controls are signed values in the -6 to 6 range and
are stored into the slice header fields slice_alpha_c0_offset_div2 and
slice_beta_offset_div2. The actual filter offsets FilterOffsetA/B are
double their value, in range of -12 to 12.
Rename variables to more closely match the nomenclature in the H.264
specification.

[ Upstream commit 1f32061e843205f6fe8404d5100d5adcec334e75 ]
On a decoder instance, after the profile has been parsed from the stream
__v4l2_ctrl_s_ctrl() is called to notify userspace about changes in the
read-only profile control. This ends up calling back into the CODA driver
where a missing check on the s_ctrl caused the profile information that has
just been parsed from the stream to be overwritten with the default
baseline profile.
Later on the driver fails to enable frame reordering, based on the wrong
profile information.

to explicitly state whether the driver needs exclusive or shared reset

This implements a simple handler for the case where decode did not finish
sucessfully. This might be helpful during normal streaming, but for now it
only handles the case where the context would deadlock with userspace,
i.e. userspace issued DEC_CMD_STOP and waits for EOS, but after the failed
decode run we would hold the context and wait for userspace to queue more
buffers.

I don't know what the BWB unit is, I guess W is for write and one of the
Bs is for burst. All I know is that there repeatedly have been issues
with it hanging on certain streams (ENGR00223231, ENGR00293425), with
various firmware versions, sometimes blocking something related to the
GDI bus or the GDI AXI adapter. There are some error cases that we don't
know how to recover from without a reboot. Apparently this unit can be
disabled by setting bit 12 in the FRAME_MEM_CTRL mailbox register to
zero, so do that to avoid crashes.
Side effects are reduced burst lengths when writing out decoded frames
to memory, so there is an "enable_bwb" module parameter to turn it back
on.

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.
After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.
To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

Replace struct v4l2_format * with void * to make queue_setup()
for common use.
And then, modify all device drivers related with this change.

Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer.
Add new member variables - bytesused, length, offset, userptr, fd,
data_offset - to struct vb2_plane in order to cover all information
of v4l2_plane.
struct vb2_plane {
<snip>
unsigned int bytesused;
unsigned int length;
union {
unsigned int offset;
unsigned long userptr;
int fd;
} m;
unsigned int data_offset;
}
Replace v4l2_buf with new member variables - index, type, memory - which
are common fields for buffer management.
struct vb2_buffer {
<snip>
unsigned int index;
unsigned int type;
unsigned int memory;
unsigned int num_planes;
struct vb2_plane planes[VIDEO_MAX_PLANES];
<snip>
};
v4l2 specific fields - flags, field, timestamp, timecode,
sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c
struct vb2_v4l2_buffer {
struct vb2_buffer vb2_buf;
__u32 flags;
__u32 field;
struct timeval timestamp;
struct v4l2_timecode timecode;
__u32 sequence;
};

Make videobuf2-v4l2 as a wrapper of videobuf2-core for v4l2-use.
And replace videobuf2-core.h with videobuf2-v4l2.h.
This renaming change should be accompanied by the modifications
of all device drivers that include videobuf2-core.h.
It can be done with just running this shell script.
replace()
{
str1=$1
str2=$2
dir=$3
for file in $(find $dir -name *.h -o -name *.c -o -name Makefile)
do
echo $file
sed "s/$str1/$str2/g" $file > $file.out
mv $file.out $file
done
}
replace "videobuf2-core" "videobuf2-v4l2" "include/media/"
replace "videobuf2-core" "videobuf2-v4l2" "drivers/media/"
replace "videobuf2-core" "videobuf2-v4l2" "drivers/usb/gadget/"
replace "videobuf2-core" "videobuf2-v4l2" "drivers/staging/media/"

This change modifies gen_pool_get() and devm_gen_pool_create() client
interfaces adding one more argument "name" of a gen_pool object.
Due to implementation gen_pool_get() is capable to retrieve only one
gen_pool associated with a device even if multiple gen_pools are created,
fortunately right at the moment it is sufficient for the clients, hence
provide NULL as a valid argument on both producer devm_gen_pool_create()
and consumer gen_pool_get() sides.
Because only one created gen_pool per device is addressable, explicitly
add a restriction to devm_gen_pool_create() to create only one gen_pool
per device, this implies two possible error codes returned by the
function, account it on client side (only misc/sram). This completes
client side changes related to genalloc updates.
