The video driver will be using the newly introduced
'will be' or 'is using'? Or will be using it for these platforms? Is
there any kind of dependency between two patches in the series?
The video driver will not be able to work without the clock side changes.
Will enabling this flag break the video driver until it is updated?
Yes, my understanding is yes it will break. When we first introduced the
flag we had got the driver and the clock changes together.
dev_pm_genpd_set_hwmode() API to switch the video GDSC to HW and SW
control modes at runtime.
Hence use HW_CTRL_TRIGGER flag instead of HW_CTRL for video GDSC's for
Qualcomm SoC SC7180 and SDM845.
Is it applicable to any other platforms? Why did you select just these
two?
The V6 version of Video driver is already using them, now the video driver
wants to migrate to v4 version of the HW to use the new flag.
I mean slightly different issue. We have following drivers:
videocc-sa8775p.c - already uses HW_CTRL_TRIGGER
videocc-sc7180.c - being converted now
videocc-sc7280.c - already uses HW_CTRL_TRIGGER
videocc-sdm845.c - being converted now
videocc-sm7150.c
videocc-sm8150.c
videocc-sm8250.c - already uses HW_CTRL_TRIGGER
videocc-sm8350.c - already uses HW_CTRL_TRIGGER
videocc-sm8450.c
videocc-sm8550.c - already uses HW_CTRL_TRIGGER
This leaves sm7150, sm8150 and sm8450 untouched. Don't they also need to
use HW_CTRL_TRIGGER?
Yes, I am okay to add the flag, but looking for the Video SW team to
confirm they are well tested on the rest of the platforms.
