- * 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>;
- };
