Due to the change in [1], vppsys0/vppsys1 are not only clock providers
and support mm system control. It's better to be described in
"mediatek,mmsys.yaml" [2] because they are not pure clock providers.

[v2 3/3] clk: mediatek: Integrate vppsys with mtk-mmsys in MT8195

[Chun-Jie Chen]

Integrate vpp0 and vpp1 with mtk-mmsys driver which
will populate device by platform_device_register_data
to start vppsys clock driver.

Hello Chun-Jie,

I agree with this series and I would be happy to give you my R-b, but
this patch will make these clocks to *never* probe in in the targeted
kernel version.

You forgot to mention that this patch will break vpp0/vpp1 clocks entirely
unless applied on top of patch series [1].

Please, either mention that said series is *required* for this one to work
as expected, or move series [1], patches 6 and 7 to this series instead;
since the MDP3 driver will need quite a while to get merged, I would suggest
to move the patches here, as to get something "complete" to merge.

Hello Chun-Jie,

I agree with this series and I would be happy to give you my R-b, but
this patch will make these clocks to *never* probe in in the targeted
kernel version.

You forgot to mention that this patch will break vpp0/vpp1 clocks entirely
unless applied on top of patch series [1].

Please, either mention that said series is *required* for this one to work
as expected, or move series [1], patches 6 and 7 to this series instead;
since the MDP3 driver will need quite a while to get merged, I would suggest
to move the patches here, as to get something "complete" to merge.

Thanks for your reminder, I only mention the dependence patch in v1,
but forgot it in v2.
