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 control
And then let's start review :)
