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

- pinctrl-names: A pinctrl state names "default" must be defined.
- pinctrl-0: Phandle referencing pin configuration of the SDHCI controller.

Example:
 
   sdhci@1f8ec000 {
       compatible = "microchip,pic32mzda-sdhci";
       reg = <0x1f8ec000 0x100>;
       interrupts = <191 IRQ_TYPE_LEVEL_HIGH>;
       clocks = <&rootclk REF4CLK>, <&rootclk PB5CLK>;
       clock-names = "base_clk", "sys_clk";
       bus-width = <4>;
       cap-sd-highspeed;
       pinctrl-names = "default";
       pinctrl-0 = <&pinctrl_sdhc1>;
   };
