1*4882a593SmuzhiyunBinding for Qualcomm Atheros AR7xxx/AR9xxx SPI controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: has to be "qca,<soc-type>-spi", "qca,ar7100-spi" as fallback.
5*4882a593Smuzhiyun- reg: Base address and size of the controllers memory area
6*4882a593Smuzhiyun- clocks: phandle of the AHB clock.
7*4882a593Smuzhiyun- clock-names: has to be "ahb".
8*4882a593Smuzhiyun- #address-cells: <1>, as required by generic SPI binding.
9*4882a593Smuzhiyun- #size-cells: <0>, also as required by generic SPI binding.
10*4882a593Smuzhiyun
11*4882a593SmuzhiyunChild nodes as per the generic SPI binding.

13*4882a593SmuzhiyunExample:
14*4882a593Smuzhiyun
15*4882a593Smuzhiyun	spi@1f000000 {

17*4882a593Smuzhiyun		reg = <0x1f000000 0x10>;
18*4882a593Smuzhiyun
19*4882a593Smuzhiyun		clocks = <&pll 2>;
20*4882a593Smuzhiyun		clock-names = "ahb";
21*4882a593Smuzhiyun
22*4882a593Smuzhiyun		#address-cells = <1>;
23*4882a593Smuzhiyun		#size-cells = <0>;
