| * 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 "nvidia,<chip>-sdhci" |
| |
| Optional properties: |
| - power-gpios : Specify GPIOs for power control |
| |
| 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 */ |
| bus-width = <8>; |
| }; |
