* 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;

};
