[RFC 0/2] exynos5250/hdmi: replace dummy hdmiphy clock with pmu reg control

[Inki Dae]

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 :)

Thanks,
Inki Dae
