Hello Krzysztof,

Thanks for yor review.

From the functions perspective:

Hardware pipeline of VDOSYS0 has these components: COLOR, CCORR, AAL,
GAMMA, DITHER.
They are related to PQ (Picture Quality) functions and they makes
VDOSYS0 supports PQ function while they are not including in VDOSYS1.

Hardware pipeline of VDOSYS1 has the component ETHDR (HDR related
component).
It makes VDOSYS1 supports the HDR function while it's not including in
VDOSYS0.

About mediatek ETHDR, you can refer to this series:

https://lore.kernel.org/all/20220819061456.8042-2-nancy.lin@mediatek.com/ (local)

To summary:
Only VDOSYS0 can support PQ adjustment.
Only VDOSYS1 can support HDR adjustment.

Is this description ok for you?
If it is ok, I will put them into commit message in next version.

Yes.

Best regards,
Krzysztof
