- qcom,max-refresh-rate:		Maximum refresh rate supported by the panel. If max refresh

					rate is not specified, then the frame rate of the panel in

					qcom,mdss-dsi-panel-framerate is used.

- qcom,dsi-dyn-clk-enable:		Boolean to indicate dsi dynamic clock switch feature

					is supported.

- qcom,dsi-dyn-clk-list:		An u32 array which lists all the supported dsi bit clock

					frequencies in Hz for the given panel.

- qcom,dsi-dyn-clk-type:		A string that specifies the sub-type for the dynamic

					clk feature. If dyn clk type is not specified, default

					value "legacy" is used.

					"legacy" = FPS is not maintained after dynamic clock switch.

					"constant-fps-adjust-hfp" = FPS is maintained even after

					dynamic clock switch by changing panel horizontal front

					"constant-fps-adjust-vfp" = FPS is maintained even after

					porch values.

					This dyn-clk-type entry is an optional binding which is

                                        contingent on the enabling of dynamic clock switch.

- qcom,mdss-dsi-bl-pmic-control-type:	A string that specifies the implementation of backlight

					control for this panel.
