* 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.
