Subject: [PATCH v2] ARM: dts: fix the clock-frequency of rinato board's panel
Date: Fri, 12 Jun 2015 19:06:50 +0900 [thread overview]
Message-ID: <1434103610-24182-1-git-send-email-human.hwang@samsung.com> (raw)
After the commit abc0b1447d4974963548777a5ba4a4457c82c426
("drm: Perform basic sanity checks on probed modes"), proper
clock-frequency becomes mandatory for validating the mode of panel.
The display does not work if there is no mode validated. Also, this
clock-frequency must be set appropriately for getting required frame
rate.
