| 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 |
| 16 | |
| 17 | Example: |
| 18 | |
| 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 | }; |
