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

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>;
