- * 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;
- };
