+* 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>;
|
|
+};
