+Device-Tree bindings for Mediatek consumer IR controller
+found in Mediatek SoC family
+
+Required properties:
+- compatible : "mediatek,mt7623-cir"
+- clocks : list of clock specifiers, corresponding to
+ entries in clock-names property;
+- clock-names : should contain "clk" entries;
+- interrupts : should contain IR IRQ number;
+- reg : should contain IO map address for IR.
+
+Optional properties:
+- linux,rc-map-name : see rc.txt file in the same directory.
+
+Example:
+
+cir: cir@10013000 {
+ compatible = "mediatek,mt7623-cir";
+ reg = <0 0x10013000 0 0x1000>;
+ interrupts = <GIC_SPI 87 IRQ_TYPE_LEVEL_LOW>;
+ clocks = <&infracfg CLK_INFRA_IRRX>;
+ clock-names = "clk";
+ linux,rc-map-name = "rc-rc6-mce";
+};
