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-binding.txt | |
16 | ||
17 | Example: | |
18 | ||
19 | sdhci@1f8ec000 { | |
20 | compatible = "microchip,pic32mzda-sdhci"; | |
21 | reg = <0x1f8ec000 0x100>; | |
22 | interrupts = <191 IRQ_TYPE_LEVEL_HIGH>; | |
684b23c1 | 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 | }; |
