Subject: S5P-TV: Warning for regulator unbalanced disables
Date: Thu, 23 Feb 2012 10:12:41 +0530 [thread overview]
Message-ID: <4F45C3C1.8030507@linaro.org> (raw)
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. [1]
