Hi Rahul,This patch is important to us. Actually, previous hdmi driver had controlled hdmiphy HDMI_PHY_CONTROL as if that were a clock but now that doesn't exist anymore. So we need to discuss how hdmiphy should be handled.
I konw that you had already posted hdmiphy relevant patch set, [PATCH 0/4] drm/exynos: hdmi: move hdmiphy related code to hdmiphy driver.I think we can couple pmu register controlling codes with that patch set without RFC. Could you update and post them again? like below,
[PATCH 0/4] drm/exynos: hdmi: move hdmiphy related code to hdmiphy driver + [RFC 0/2] exynos5250/hdmi: replace dummy hdmiphy clock with pmu reg controlAnd then let's start review :)
And I think It would be better to move the pmu register controlling codes into hdmiphy driver like drivers/usb/phy/phy-samsung-usb2.c driver does.
Thanks,

Previously, hdmiphy is added as a dummy clock in clock file for
exynos SoCs. Enable/Disable to this clock, actually toggles the power
control bit in PMU, instead of controlling the clock gate.
This RFC adds the support to parse hdmiphy control node which is a child
node to hdmi, and map the pmu register to toggle the power control bit.
This is based on drm-next branch in Inki Dae's tree.
