- * 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 one of:
- - "nvidia,tegra20-sdhci": for Tegra20
- - "nvidia,tegra30-sdhci": for Tegra30
- - "nvidia,tegra114-sdhci": for Tegra114
- - "nvidia,tegra124-sdhci": for Tegra124 and Tegra132
- - "nvidia,tegra210-sdhci": for Tegra210
- - "nvidia,tegra186-sdhci": for Tegra186
- - clocks : Must contain one entry, for the module clock.
- See ../clocks/clock-bindings.txt for details.
- - resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
- - reset-names : Must include the following entries:
- - sdhci
- Optional properties:
- - power-gpios : Specify GPIOs for power control
- Example:
- sdhci@c8000200 {
- compatible = "nvidia,tegra20-sdhci";
- reg = <0xc8000200 0x200>;
- interrupts = <47>;
- clocks = <&tegra_car 14>;
- resets = <&tegra_car 14>;
- reset-names = "sdhci";
- cd-gpios = <&gpio 69 0>; /* gpio PI5 */
- wp-gpios = <&gpio 57 0>; /* gpio PH1 */
- power-gpios = <&gpio 155 0>; /* gpio PT3 */
- bus-width = <8>;
- };
