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.
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.
