Socionext UniPhier SPI controller driver | ||
|
||
UniPhier SoCs have SCSSI which supports SPI single channel. | ||
|
||
Required properties: | ||
- compatible: should be "socionext,uniphier-scssi" | ||
- reg: address and length of the spi master registers | ||
- #address-cells: must be <1>, see spi-bus.txt | ||
- #size-cells: must be <0>, see spi-bus.txt | ||
- clocks: A phandle to the clock for the device. | ||
- resets: A phandle to the reset control for the device. | ||
|
||
Example: | ||
|
||
spi0: spi@54006000 { | ||
compatible = "socionext,uniphier-scssi"; | ||
reg = <0x54006000 0x100>; | ||
#address-cells = <1>; | ||
#size-cells = <0>; | ||
clocks = <&peri_clk 11>; | ||
resets = <&peri_rst 11>; | ||
}; |
