Hi, After implementing genpd framework for EXYNOS4, (Ref commit 91cfbd4 "ARM: EXYNOS: Hook up power domains to generic power domain infrastructure" in Kukjin's for-next branch), we are getting following warning from s5p-hdmi driver. The test was done on Origen board with code based on 3.3-rc4 and Kukjin's for-next branch.
