Binding for Qualcomm Atheros AR7xxx/AR9xxx SPI controller
Required properties:
- compatible: has to be "qca,<soc-type>-spi", "qca,ar7100-spi" as fallback.
- reg: Base address and size of the controllers memory area
- clocks: phandle of the AHB clock.
- clock-names: has to be "ahb".
- #address-cells: <1>, as required by generic SPI binding.
- #size-cells: <0>, also as required by generic SPI binding.
Child nodes as per the generic SPI binding.
Example:
spi@1f000000 {
compatible = "qca,ar9132-spi", "qca,ar7100-spi";
reg = <0x1f000000 0x10>;
clocks = <&pll 2>;
clock-names = "ahb";
#address-cells = <1>;
#size-cells = <0>;
};
