3Required properties:
4- compatible:
5 * "qcom,mdp" - mdp4
6- reg: Physical base address and length of the controller's registers.
7- interrupts: The interrupt signal from the display controller.
8- connectors: array of phandles for output device(s)
9- clocks: device clocks
10 See ../clocks/clock-bindings.txt for details.
11- clock-names: the following clocks are required:
12 * "core_clk"
13 * "iface_clk"
14 * "lut_clk"
15 * "src_clk"
16 * "hdmi_clk"
17 * "mpd_clk"
