* 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-bindings.txt
|
|
|
|
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>;
|
|
};
