- +MTK SPI device
- +
- +Required properties:
- +- compatible: should be one of the following.
- + - mediatek,mt8173-spi: for mt8173 platforms
- + - mediatek,mt8135-spi: for mt8135 platforms
- + - mediatek,mt6589-spi: for mt6589 platforms
- +
- +- reg: Address and length of the register set for the device
- +
- +- interrupts: Should contain spi interrupt
- +
- +- clock-names: tuple listing input clock names.
- + Required elements: "main"
- +
- +- clocks: phandles to input clocks.
- +
- +- pad-select: should specify spi pad used, only required for MT8173.
- + This value should be 0~3.
- +
- +Example:
- +
- +- SoC Specific Portion:
- +spi: spi@1100a000 {
- + compatible = "mediatek,mt8173-spi";
- + reg = <0 0x1100a000 0 0x1000>;
- + interrupts = <GIC_SPI 110 IRQ_TYPE_LEVEL_LOW>;
- + clocks = <&pericfg PERI_SPI0>;
- + clock-names = "main";
- + pad-select = <1>;
- + status = "disabled";
- +};
