From 91e28030fd5deb56b5f14b870bc2e2c856435cca Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Wed, 25 Jul 2018 17:46:44 +0200 Subject: [PATCH] dt-bindings: exynos_dsim: update of graph bindings Of-graph bindings should describe ports present in the device, not the devices it can be connected to. The patch replaces verbose description with shorter but more precise one. While at it clock related properties are moved to the main node as it is their actual location.
