| 2 | |
| 3 | UniPhier SoCs have SCSSI which supports SPI single channel. |
| 4 | |
| 5 | Required properties: |
| 6 | - compatible: should be "socionext,uniphier-scssi" |
| 7 | - reg: address and length of the spi master registers |
| Keiji Hayashibara | 3511ba7 | 2018-10-24 18:34:29 +0900 | [diff] [blame] | 8 | - interrupts: a single interrupt specifier |
| 9 | - pinctrl-names: should be "default" |
| 10 | - pinctrl-0: pin control state for the default mode |
| 11 | - clocks: a phandle to the clock for the device |
| 12 | - resets: a phandle to the reset control for the device |

| 16 | spi0: spi@54006000 { |

| 18 | reg = <0x54006000 0x100>; |

| 21 | pinctrl-0 = <&pinctrl_spi0>; |
