This gets us in sync with dts from kernel 4.11. Two patches were already backported earlier. I decided to use 03x prefix as it's kind of similar to the 3xx prefix: 3xx - architecture specific patches It isn't any documented or strict rule though. We don't need to stick to it if we hit any problems. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

Subject: [PATCH] ARM: bcm2835: dt: Add the DSI module nodes and clocks.
|
|
|
|
The modules stay disabled by default, and if you want to enable DSI
|
|
you'll need an overlay that connects a panel to it.
