Once done we can move on to enabling these clocks in the DTS and switch on
the venus.

Bryan O'Donoghue (4):
   dt-bindings: clock: Add missing SM8250 videoc clock indices
   clk: qcom: videocc: Add sm8250 VIDEO_CC_MVS0_DIV_CLK_SRC
   clk: qcom: videocc: Add sm8250 VIDEO_CC_MVS0_CLK
   clk: qcom: videocc: Add gdsc mmcx-reg supply hook

I remember now the old discussion about these two clocks
(https://lore.kernel.org/linux-arm-msm/160092826778.310579.12225989905897101118@xxxxxxxxxxxxxxxxxxxxxxxxxx/).

Is the message. reported by Jonathan, solved by the mmcx-reg supply?

The stuck problem is a bandwidth problem not a regulator problem, there's some internal clock dependency we don't have visibility of.

Both of these resolve,

Jonathan had a hack:
https://git.linaro.org/people/bryan.odonoghue/kernel.git/commit/?h=tracking-qcomlt-sm8250-09-11-20%2bvenus-flto-simple-test2&id=d4bea74282d14244127a1e97766b6108ec68e22f

Dikshita proposed this instead, which, we will send out soon:
https://git.linaro.org/people/bryan.odonoghue/kernel.git/commit/?h=tracking-qcomlt-sm8250-venus-integrated-sm8250&id=782202d611761e639af7e44d8344c0c098642b9f

Also are these clocks necessary at all?

Eh well I'm not sure what happens if I try to dump the clocks but, this is an accurate representation of what is done downstream so..
