| * 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>; | |
| }; |
