Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.

* 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"
|
|
- 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>;
|
|
};
