Subject: [PATCH v4,1/6] media: mtk-vcodec: venc: remove redundant code

From: Alexandre Courbot <[email protected]>

vidioc_try_fmt() does clamp height and width when called on the OUTPUT
queue, so clamping them prior to calling this function is redundant. Set
the queue's parameters after calling vidioc_try_fmt() so we can use the
values it computed.

From the guideline[1]:
Notably, the last Signed-off-by: must always be that of the developer
submitting the patch

You should provide your signed-off.

Subject: [PATCH v4,2/6] dt-bindings: media: mtk-vcodec: Add dma-ranges property

The mt8192 iommu support 0~16GB iova. We separate it to four banks:
0~4G; 4G~8G; 8G~12G; 12G~16G.

The "dma-ranges" could be used to adjust the bank we locate.
If we don't set this property. The default range always is 0~4G.

Here we don't have actual bus/parent concept here. And the iova
requirement is for our HW. Thus put the property in our node.

If all three models mt8173, mt8183 and mt8192 support the same formats then
we should probably not name the structs according to one of the models, so maybe:

s/mtk_video_formats_capture_mt8183/mtk_video_formats_capture/
s/mtk_video_formats_output_mt8173/mtk_video_formats_output/

or some other naming

Thanks,

This define is never used so it can be removed.

Thanks for your review and comments, we will rename these in another
patchset, this patchset just for MT8192 now.
