* 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.
