++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";
++};
