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 : For Tegra20, must contain "nvidia,tegra20-sdhci".
11 For Tegra30, must contain "nvidia,tegra30-sdhci". For Tegra114,
12 must contain "nvidia,tegra114-sdhci". For Tegra124, must contain
13 "nvidia,tegra124-sdhci". Otherwise, must contain "nvidia,<chip>-sdhci",
14 plus one of the above, where <chip> is tegra132 or tegra210.
15 - clocks : Must contain one entry, for the module clock.
16 See ../clocks/clock-bindings.txt for details.
17 - resets : Must contain an entry for each entry in reset-names.
18 See ../reset/reset.txt for details.
19 - reset-names : Must include the following entries:
23 - power-gpios : Specify GPIOs for power control
