+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";
+};
