Subject: ARM: dts: lager: Add CEC clock for HDMI transmitter
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c5aa87977626e778e1ee3bd03b14a300d9338a3a;p=openwrt%2Fstaging%2Fblogic.git

ARM: dts: lager: Add CEC clock for HDMI transmitter

The adv7511 on the Lager board has a 12 MHz fixed clock
for the CEC block. Specify this in the dts to enable CEC support.

Based on a similar patch for Koelsch by Hans Verkuil.
