Subject: [PATCH 04/18] media: rkvdec: h264: Fix reference frame_num wrap for
second field
When decoding the second field in a complementary field pair the second
field is sharing the same frame_num with the first field.
Currently the frame_num for the first field is wrapped when it matches the
field being decoded, this cause issues to decode the second field in a
complementary field pair.
Fix this by using inclusive comparison, less than or equal.

Subject: [PATCH 06/18] media: rkvdec: h264: Validate and use pic width and
height in mbs
The width and height in mbs is currently configured based on OUTPUT buffer
resolution, this works for frame pictures but can cause issues for field
pictures.
When frame_mbs_only_flag is 0 the height in mbs should be height of
the field instead of height of frame.
Validate pic_width_in_mbs_minus1 and pic_height_in_map_units_minus1
against OUTPUT buffer resolution and use these values to configure HW.

Subject: [PATCH 07/18] media: rkvdec: h264: Fix bit depth wrap in pps packet
The luma and chroma bit depth fields in the pps packet is 3 bits wide.
8 is wrongly added to the bit depth value written to these 3-bit fields.
Because only the 3 LSB is written the hardware is configured correctly.
Correct this by not adding 8 to the luma and chroma bit depth value.

Subject: [PATCH 10/18] media: v4l2: Add NV15 and NV20 pixel formats
Add NV15 and NV20 pixel formats used by the Rockchip Video Decoder for
10-bit buffers.
NV15 and NV20 is a packed 10-bit 4:2:0/4:2:2 semi-planar Y/CbCr format
similar to P010 and P210 but has no padding between components. Instead,
luminance and chrominance samples are grouped into 4s so that each group is
packed into an integer number of bytes:
YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes
The '15' and '20' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a multiple
of 8 for NV15 and 4 for NV20.

Use bytesperline and buffer height to calculate the strides configured.
This does not really change anything other than ensuring the bytesperline
that is signaled to userspace matches what is configured in HW.

Subject: [PATCH 14/18] media: rkvdec: h264: Support High 10 and 4:2:2 profiles
Add support and enable decoding of H264 High 10 and 4:2:2 profiles.
Decoded CAPTURE buffer width is aligned to 64 pixels to accommodate HW
requirement on 10-bit format buffers.
The new valid_fmt operation is implemented and return a valid pixelformat
for the provided SPS control.

Subject: [PATCH 15/18] media: rkvdec: h264: Support profile and level controls
The Rockchip Video Decoder used in RK3399 supports H.264 profiles from
Baseline to High 4:2:2 up to Level 5.1, except for the Extended profile.
Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE and the
V4L2_CID_MPEG_VIDEO_H264_LEVEL control, so that userspace can query the
driver for the list of supported profiles and level.

Subject: [PATCH 17/18] drm: drm_fourcc: add NV20 and NV30 YUV formats
DRM_FORMAT_NV20 and DRM_FORMAT_NV30 formats is the 2x1 and non-subsampled
variant of NV15, a 10-bit 2-plane YUV format that has no padding between
components. Instead, luminance and chrominance samples are grouped into 4s
so that each group is packed into an integer number of bytes:
YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes
The '20' and '30' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a multiple
of 4.
V2: Added NV30 format
