[PATCH 04/47] ARM: dts: lager: Add CEC clock for HDMI transmitter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx>

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.
