Subject: [PATCH v3 0/6] dt-bindings: Firmware node binding for ZynqMP core 

Base firmware node and clock child node binding are part of mainline kernel.
This patchset adds documentation to describe rest of the firmware child node bindings. 

Complete firmware DT node example is shown below for ease of understanding:

firmware {
	zynqmp_firmware: zynqmp-firmware {
		compatible = "xlnx,zynqmp-firmware";
		method = "smc";
		#power-domain-cells = <1>;
		#reset-cells = <1>;

		zynqmp_clk: clock-controller {
			#clock-cells = <1>;
			compatible = "xlnx,zynqmp-clk";
			clocks = <&pss_ref_clk>, <&video_clk>, <&pss_alt_ref_clk>, <&aux_ref_clk>, <&gt_crx_ref_clk>;
			clock-names = "pss_ref_clk", "video_clk", "pss_alt_ref_clk","aux_ref_clk", "gt_crx_ref_clk";
		};

		zynqmp_power: zynqmp-power {
			compatible = "xlnx,zynqmp-power";
			interrupts = <0 35 4>;
		};

		zynqmp_reset: reset-controller {
			compatible = "xlnx,zynqmp-reset";
			#reset-cells = <1>;
		};
	
		nvmem_firmware {
			compatible = "xlnx,zynqmp-nvmem-fw";
			#address-cells = <1>;
			#size-cells = <1>;

			/* Data cells */
			soc_revision: soc_revision {
				reg = <0x0 0x4>;
			};
		};

		pinctrl0: pinctrl@...80000 {
			compatible = "xlnx,zynqmp-pinctrl";

			pinctrl_uart1_default: uart1-default {
				mux {
					groups = "uart0_4_grp";
					function = "uart0";
				};
	
				conf {
					groups = "uart0_4_grp";
					slew-rate = <SLEW_RATE_SLOW>;
					io-standard = <IO_STANDARD_LVCMOS18>;
				};
	
				conf-rx {
					pins = "MIO18";
					bias-high-impedance;
				};
	
				conf-tx {
					pins = "MIO19";
					bias-disable;
					schmitt-cmos = <PIN_INPUT_TYPE_CMOS>;
				};
			};
		};
	};
};
