Align compatible strings for several IP blocks present on Tegra chips with the latest doctrine from the DT maintainers: http://marc.info/?l=devicetree&m=142255654213019&w=2 The primary objective here is to avoid checkpatch warnings, per: http://marc.info/?l=linux-tegra&m=142201349727836&w=2 DT binding text files have been updated for the following IP blocks: - PCIe - SOR - SoC timers - AHB "gizmo" - APB_MISC - pinmux control - UART - PWM - I2C - SPI - RTC - PMC - eFuse - AHCI - HDA - XUSB_PADCTRL - SDHCI - SOC_THERM - AHUB - I2S - EHCI - USB PHY N.B. The nvidia,tegra20-timer compatible string is removed from the nvidia,tegra30-timer.txt documentation file because it's already mentioned in the nvidia,tegra20-timer.txt documentation file. This second version takes into account the following requests from Rob Herring <robherring2@gmail.com>: - Per-IP block patches have been combined into a single patch - Explicit documentation about which compatible strings are actually matched by the driver has been removed. In its place is implicit documentation that loosely follows Rob's prescribed format: "Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where <chip> is tegra30, tegra132, ..."

* 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 : For Tegra20, must contain "nvidia,tegra20-sdhci".
|
|
For Tegra30, must contain "nvidia,tegra30-sdhci". For Tegra114,
|
|
must contain "nvidia,tegra114-sdhci". For Tegra124, must contain
|
|
"nvidia,tegra124-sdhci". Otherwise, must contain "nvidia,<chip>-sdhci",
|
|
plus one of the above, where <chip> is tegra132 or tegra210.
|
|
- 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>;
|
|
};
