In commit 7662d1dc17d4 ("spi: uniphier: fix incorrect property items")
addressing properties of #address-cells and #size-cells were removed.
Since it is not necessary to remove them, they are back again.

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
|
|
- interrupts: a single interrupt specifier
|
|
- pinctrl-names: should be "default"
|
|
- pinctrl-0: pin control state for the default mode
|
|
- 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>;
|
|
interrupts = <0 39 4>;
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&pinctrl_spi0>;
|
|
clocks = <&peri_clk 11>;
|
|
resets = <&peri_rst 11>;
|
|
};
