Device Tree Bindings for the Arasan SDHCI Controller
|
|
|
|
The bindings follow the mmc[1], clock[2] and interrupt[3] bindings. Only
|
|
deviations are documented here.

|
|
[1] Documentation/devicetree/bindings/mmc/mmc.txt
|
|
[2] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
[3] Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
|
|
|
|
Required Properties:
|
|
- compatible: Compatibility string. Must be 'arasan,sdhci-8.9a'
|
|
- reg: From mmc bindings: Register location and length.
|
|
- clocks: From clock bindings: Handles to clock inputs.
|
|
- clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb"
|
|
- interrupts: Interrupt specifier
|
|
- interrupt-parent: Phandle for the interrupt controller that services
|
|
interrupts for this device.
|
|
|
|
Example:
|
|
sdhci@e0100000 {
|
|
compatible = "arasan,sdhci-8.9a";
|
|
reg = <0xe0100000 0x1000>;
|
|
clock-names = "clk_xin", "clk_ahb";
|
|
clocks = <&clkc 21>, <&clkc 32>;
|
|
interrupt-parent = <&gic>;
|
|
interrupts = <0 24 4>;
|
|
} ;
