Hi All,

This patch series introduces several enhancements to the Qualcomm Iris
encoder driver, improving support for V4L2 controls and enabling more
video encoding features.

All patches have been tested with v4l2-compliance, v4l2-ctl and
on QCS8300 for encoder.

Commands used for V4l2-ctl validation:

Scale:
v4l2-ctl --verbose -d /dev/video1 \
--set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 \
--set-selection-output target=crop,width=1920,height=1080 \
--set-fmt-video=width=1280,height=720,pixelformat=H264 \
--stream-mmap --stream-out-mmap \
--stream-from=input_nv12_1080p.yuv \
--stream-to=output/scale_720p_output.h264

Flip:
v4l2-ctl --verbose -d /dev/video1 \
--set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 \
--set-selection-output target=crop,width=1920,height=1080 \
--set-fmt-video=pixelformat=H264 --stream-mmap --stream-out-mmap \
--stream-from=input_nv12_1080p.yuv \
--stream-to=output/vertical_flip.h264 \
--set-ctrl vertical_flip=1

v4l2-ctl --verbose -d /dev/video1 \
--set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 \
--set-selection-output target=crop,width=1920,height=1080 \
--set-fmt-video=pixelformat=H264 --stream-mmap --stream-out-mmap \
--stream-from=input_nv12_1080p.yuv \
--stream-to=output/horizontal_flip.h264 \
--set-ctrl horizontal_flip=1

Rotate:
v4l2-ctl --verbose -d /dev/video1 \
--set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 \
--set-selection-output target=crop,width=1920,height=1080 \
--set-fmt-video=pixelformat=H264 --stream-mmap --stream-out-mmap \
--stream-from=input_nv12_1080p.yuv \
--stream-to=output/rotate90.h264 \
--set-ctrl rotate=90

v4l2-ctl --verbose -d /dev/video1 \
--set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 \
--set-selection-output target=crop,width=1920,height=1080 \
--set-fmt-video=pixelformat=H264 --stream-mmap --stream-out-mmap \
--stream-from=input_nv12_1080p.yuv \
--stream-to=output/rotate180.h264 \
--set-ctrl rotate=180

v4l2-ctl --verbose -d /dev/video1 \
--set-fmt-video-out=width=1920,height=1080,pixelformat=NV12 \
--set-selection-output target=crop,width=1920,height=1080 \
--set-fmt-video=pixelformat=H264 --stream-mmap --stream-out-mmap \
--stream-from=input_nv12_1080p.yuv \
--stream-to=output/rotate270.h264 \
--set-ctrl rotate=270

I've run this serie on SM8650-HDK, and all test works (+ visually confirmed)
except the rotate90 & rotate270 which fails with:
[ 113.494611] qcom-iris aa00000.video-codec: session error received 0x1000005: unknown
printed on dmesg.

Do you know if those operations are supposed to work on the sm8650 hw & fw ?
