- * Samsung's SDHCI Controller device tree bindings
- Samsung's SDHCI controller is used as a connectivity interface with external
- MMC, SD and eMMC storage mediums. This file documents differences between the
- core mmc properties described by mmc.txt and the properties used by the
- Samsung implementation of the SDHCI controller.
- Required SoC Specific Properties:
- - compatible: should be one of the following
- - "samsung,s3c6410-sdhci": For controllers compatible with s3c6410 sdhci
- controller.
- - "samsung,exynos4210-sdhci": For controllers compatible with Exynos4 sdhci
- controller.
- Required Board Specific Properties:
- - pinctrl-0: Should specify pin control groups used for this controller.
- - pinctrl-names: Should contain only one value - "default".
- Example:
- sdhci@12530000 {
- compatible = "samsung,exynos4210-sdhci";
- reg = <0x12530000 0x100>;
- interrupts = <0 75 0>;
- bus-width = <4>;
- cd-gpios = <&gpk2 2 0>;
- pinctrl-names = "default";
- pinctrl-0 = <&sd0_clk &sd0_cmd &sd0_bus4>;
- };
- Note: This example shows both SoC specific and board specific properties
- in a single device node. The properties can be actually be separated
- into SoC specific node and board specific node.
