Subject: [PATCH 1/2] arm64: dts: qcom: glymur: Describe display related
nodes
The MDSS (Mobile Display SubSystem) on Glymur comes with 4 DisplayPort
controllers. Describe them along with display controller and the eDP
PHY. Then, attach the combo PHYs link and vco_div clocks to the Display
clock controller and link up the PHYs and DP endpoints in the graph.
