This file documents the differences between the core properties in
|
||
|
|
Documentation/devicetree/bindings/mmc/mmc.txt and the properties
|
||
|
|
used by the sdhci-st driver.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : Must be "st,sdhci"
|
||
|
|
- clock-names : Should be "mmc"
|
||
|
|
See: Documentation/devicetree/bindings/resource-names.txt
|
||
|
|
- clocks : Phandle of the clock used by the sdhci controler
|
||
|
|
See: Documentation/devicetree/bindings/clock/clock-bindings.txt
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- non-removable: non-removable slot
|
||
|
|
See: Documentation/devicetree/bindings/mmc/mmc.txt
|
||
|
|
- bus-width: Number of data lines
|
||
|
|
See: Documentation/devicetree/bindings/mmc/mmc.txt

|
|
Example:
|
||
|
|
|
||
|
|
mmc0: sdhci@fe81e000 {
|
||
|
|
compatible = "st,sdhci";
|
||
|
|
status = "disabled";
|
||
|
|
reg = <0xfe81e000 0x1000>;
|
||
|
|
interrupts = <GIC_SPI 127 IRQ_TYPE_NONE>;
|
||
|
|
interrupt-names = "mmcirq";
|
||
|
|
pinctrl-names = "default";
|
||
|
|
pinctrl-0 = <&pinctrl_mmc0>;
|
||
|
|
clock-names = "mmc";
|
||
|
|
clocks = <&clk_s_a1_ls 1>;
|
||
|
|
bus-width = <8>
|
