+* NVIDIA Tegra Secure Digital Host Controller
+
+This controller on Tegra family SoCs provides an interface for MMC, SD,
+and SDIO types of memory cards.
+
+Required properties:
+- compatible : Should be "nvidia,<chip>-sdhci"
+- reg : Should contain SD/MMC registers location and length
+- interrupts : Should contain SD/MMC interrupt
+
+Optional properties:
+- cd-gpios : Specify GPIOs for card detection
+- wp-gpios : Specify GPIOs for write protection
+- power-gpios : Specify GPIOs for power control
+- support-8bit : Boolean, indicates if 8-bit mode should be used.
+
+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 */
+        support-8bit;
+};
