| * 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>; |
| }; |
