1 * Samsung's SDHCI Controller device tree bindings
3 Samsung's SDHCI controller is used as a connectivity interface with external
4 MMC, SD and eMMC storage mediums. This file documents differences between the
5 core mmc properties described by mmc.txt and the properties used by the
6 Samsung implementation of the SDHCI controller.
8 Required SoC Specific Properties:
9 - compatible: should be one of the following
10 - "samsung,s3c6410-sdhci": For controllers compatible with s3c6410 sdhci
12 - "samsung,exynos4210-sdhci": For controllers compatible with Exynos4 sdhci
15 Required Board Specific Properties:
16 - pinctrl-0: Should specify pin control groups used for this controller.
17 - pinctrl-names: Should contain only one value - "default".
21 compatible = "samsung,exynos4210-sdhci";
22 reg = <0x12530000 0x100>;
23 interrupts = <0 75 0>;
25 cd-gpios = <&gpk2 2 0>;
26 pinctrl-names = "default";
27 pinctrl-0 = <&sd0_clk &sd0_cmd &sd0_bus4>;
30 Note: This example shows both SoC specific and board specific properties
31 in a single device node. The properties can be actually be separated
32 into SoC specific node and board specific node.
