| Subject: [PATCH 1065/1795] ARM: dts: lager: Add CEC clock for HDMI transmitter |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| 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. |
