++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";
++};
