This file documents differences between the core properties in mmc.txt
|
|
and the properties present in the bcm281xx SDHCI
|
|
|
|
Required properties:
|
|
- compatible : Should be "brcm,kona-sdhci"
|
|
- DEPRECATED: compatible : Should be "bcm,kona-sdhci"
|
|
- clocks: phandle + clock specifier pair of the external clock
|
|
|
|
Refer to clocks/clock-bindings.txt for generic clock consumer properties.

Example:
|
|
|
|
sdio2: sdio@0x3f1a0000 {
|
|
compatible = "brcm,kona-sdhci";
|
|
reg = <0x3f1a0000 0x10000>;
|
|
clocks = <&sdio3_clk>;
|
|
interrupts = <0x0 74 0x4>;
|
|
};
