1* Microchip PIC32 SDHCI Controller 2 3This file documents differences between the core properties in mmc.txt 4and the properties used by the sdhci-pic32 driver. 5 6Required properties: 7- compatible: Should be "microchip,pic32mzda-sdhci" 8- interrupts: Should contain interrupt 9- clock-names: Should be "base_clk", "sys_clk". 10 See: Documentation/devicetree/bindings/resource-names.txt 11- clocks: Phandle to the clock. 12 See: Documentation/devicetree/bindings/clock/clock-bindings.txt 13- pinctrl-names: A pinctrl state names "default" must be defined. 14- pinctrl-0: Phandle referencing pin configuration of the SDHCI controller. 15 See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt 16 17Example: 18 19 sdhci@1f8ec000 { 20 compatible = "microchip,pic32mzda-sdhci"; 21 reg = <0x1f8ec000 0x100>; 22 interrupts = <191 IRQ_TYPE_LEVEL_HIGH>; 23 clocks = <&rootclk REF4CLK>, <&rootclk PB5CLK>; 24 clock-names = "base_clk", "sys_clk"; 25 bus-width = <4>; 26 cap-sd-highspeed; 27 pinctrl-names = "default"; 28 pinctrl-0 = <&pinctrl_sdhc1>; 29 }; 30
