1 * NVIDIA Tegra Secure Digital Host Controller
3 This controller on Tegra family SoCs provides an interface for MMC, SD,
4 and SDIO types of memory cards.
6 This file documents differences between the core properties described
7 by mmc.txt and the properties used by the sdhci-tegra driver.
10 - compatible : Should be "nvidia,<chip>-sdhci"
11 - clocks : Must contain one entry, for the module clock.
12 See ../clocks/clock-bindings.txt for details.
13 - resets : Must contain an entry for each entry in reset-names.
14 See ../reset/reset.txt for details.
15 - reset-names : Must include the following entries:
19 - power-gpios : Specify GPIOs for power control
