1Device Tree Bindings for the Arasan SDHCI Controller 2 3 The bindings follow the mmc[1], clock[2] and interrupt[3] bindings. Only 4 deviations are documented here. 5 6 [1] Documentation/devicetree/bindings/mmc/mmc.txt 7 [2] Documentation/devicetree/bindings/clock/clock-bindings.txt 8 [3] Documentation/devicetree/bindings/interrupt-controller/interrupts.txt 9 10Required Properties: 11 - compatible: Compatibility string. Must be 'arasan,sdhci-8.9a' or 12 'arasan,sdhci-4.9a' or 'arasan,sdhci-5.1' 13 - reg: From mmc bindings: Register location and length. 14 - clocks: From clock bindings: Handles to clock inputs. 15 - clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb" 16 - interrupts: Interrupt specifier 17 - interrupt-parent: Phandle for the interrupt controller that services 18 interrupts for this device. 19 20Example: 21 sdhci@e0100000 { 22 compatible = "arasan,sdhci-8.9a"; 23 reg = <0xe0100000 0x1000>; 24 clock-names = "clk_xin", "clk_ahb"; 25 clocks = <&clkc 21>, <&clkc 32>; 26 interrupt-parent = <&gic>; 27 interrupts = <0 24 4>; 28 } ; 29
