* Microchip PIC32 SDHCI Controller



This file documents differences between the core properties in mmc.txt

and the properties used by the sdhci-pic32 driver.



Required properties:

- compatible: Should be "microchip,pic32mzda-sdhci"

- interrupts: Should contain interrupt

- clock-names: Should be "base_clk", "sys_clk".

               See: Documentation/devicetree/bindings/resource-names.txt

- clocks: Phandle to the clock.

          See: Documentation/devicetree/bindings/clock/clock-bindings.txt

- pinctrl-names: A pinctrl state names "default" must be defined.

- pinctrl-0: Phandle referencing pin configuration of the SDHCI controller.

             See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt



Example:



	sdhci@1f8ec000 {

		compatible = "microchip,pic32mzda-sdhci";

		reg = <0x1f8ec000 0x100>;

		interrupts = <191 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&REFCLKO4>, <&PBCLK5>;

		clock-names = "base_clk", "sys_clk";

		bus-width = <4>;

		cap-sd-highspeed;

		pinctrl-names = "default";

		pinctrl-0 = <&pinctrl_sdhc1>;

	};
