++* MTK MMC controller
++
++The MTK MSDC can act as a MMC controller
++to support MMC, SD, and SDIO types of memory cards.
++
++This file documents differences between the core properties in mmc.txt
++and the properties used by the msdc driver.
++
++Required properties:
++- compatible: Should be "mediatek,mt8173-mmc","mediatek,mt8135-mmc"
++- interrupts: Should contain MSDC interrupt number
++- clocks: MSDC source clock, HCLK
++- clock-names: "source", "hclk"
++- pinctrl-names: should be "default", "state_uhs"
++- pinctrl-0: should contain default/high speed pin ctrl
++- pinctrl-1: should contain uhs mode pin ctrl
++- vmmc-supply: power to the Core
++- vqmmc-supply: power to the IO
++
++Examples:
++mmc0: mmc@11230000 {
++ compatible = "mediatek,mt8173-mmc", "mediatek,mt8135-mmc";
++ reg = <0 0x11230000 0 0x108>;
++ interrupts = <GIC_SPI 39 IRQ_TYPE_LEVEL_LOW>;
++ vmmc-supply = <&mt6397_vemc_3v3_reg>;
++ vqmmc-supply = <&mt6397_vio18_reg>;
++ clocks = <&pericfg CLK_PERI_MSDC30_0>, <&topckgen CLK_TOP_MSDC50_0_H_SEL>;
++ clock-names = "source", "hclk";
++ pinctrl-names = "default", "state_uhs";
++ pinctrl-0 = <&mmc0_pins_default>;
++ pinctrl-1 = <&mmc0_pins_uhs>;
++};
