Archit Taneja d2252563ee dt-bindings: drm/msm: Update MDP bindings
Update DT bindings for mdp. We now have a more uniform and future-proof
set of compatible strings.

MDP5 bindings were missing. Add those and update details on the
clock-names properties.

Qualcomm adreno/snapdragon display controller
Required properties:
- compatible:
* "qcom,mdp4" - mdp4
* "qcom,mdp5" - mdp5
- reg: Physical base address and length of the controller's registers.
- interrupts: The interrupt signal from the display controller.
- connectors: array of phandles for output device(s)
- clocks: device clocks
See ../clocks/clock-bindings.txt for details.
- clock-names: the following clocks are required.
For MDP4:
* "core_clk"
* "iface_clk"
* "lut_clk"
* "src_clk"
* "hdmi_clk"
* "mdp_clk"
For MDP5:
* "bus_clk"
* "iface_clk"
* "core_clk_src"
* "core_clk"
* "lut_clk" (some MDP5 versions may not need this)
* "vsync_clk"
Optional properties:
- gpus: phandle for gpu device
- clock-names: the following clocks are optional:
* "lut_clk"
Example:
/ {
...
