1 * Microchip PIC32 SDHCI Controller
2
3 This file documents differences between the core properties in mmc.txt
4 and the properties used by the sdhci-pic32 driver.
5
6 Required 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-bindings.txt

17 Example:

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 };
