Kukjin,

This patch is -rc material and is needed to have display working in
3.18 again since commit a5ec598 ("phy: exynos-dp-video: Use syscon
support to control pmu register") landed in 3.18 and broke the Exynos
Display Port PHY:

exynos-dp-video-phy 10040728.video-phy: Failed to lookup PMU regmap

Best regards,
Javier

Sorry for not adding Kukjin to the list and thereby for the delay
about this patch.

Yes, we should pick this up and merge it since the driver patch is merged now.

No worries but I'm not sure if Kukjin is aware of this patch. I see he
has been applying other patches but didn't pick $subject.

Maybe you can resend it to Kukjin just to be sure he will have it in
his mailbox?

Best regards,
Javier
