+* NVIDIA Tegra Secure Digital Host Controller
+
+This controller on Tegra family SoCs provides an interface for MMC, SD,
+and SDIO types of memory cards.
+
+This file documents differences between the core properties described
+by mmc.txt and the properties used by the sdhci-tegra driver.
+
+Required properties:
+- compatible : Should be "nvidia,<chip>-sdhci"
+
+Optional properties:
+- power-gpios : Specify GPIOs for power control
+
+Example:
+
+sdhci@c8000200 {
+ compatible = "nvidia,tegra20-sdhci";
+ reg = <0xc8000200 0x200>;
+ interrupts = <47>;
+ cd-gpios = <&gpio 69 0>; /* gpio PI5 */
+ wp-gpios = <&gpio 57 0>; /* gpio PH1 */
+ power-gpios = <&gpio 155 0>; /* gpio PT3 */
+ bus-width = <8>;
+};
