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 Tegra30 HDA controller
|
|
|
|
Required properties:
|
|
- compatible : For Tegra30, must contain "nvidia,tegra30-hda". Otherwise,
|
|
must contain '"nvidia,<chip>-hda", "nvidia,tegra30-hda"', where <chip> is
|
|
tegra114, tegra124, or tegra132.
|
|
- reg : Should contain the HDA registers location and length.
|
|
- interrupts : The interrupt from the HDA controller.
|
|
- clocks : Must contain an entry for each required entry in clock-names.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- clock-names : Must include the following entries: hda, hdacodec_2x, hda2hdmi
|
|
- resets : Must contain an entry for each entry in reset-names.
|
|
See ../reset/reset.txt for details.
|
|
- reset-names : Must include the following entries: hda, hdacodec_2x, hda2hdmi
|
|
|
|
Example:
|
|
|
|
hda@0,70030000 {
|
|
compatible = "nvidia,tegra124-hda", "nvidia,tegra30-hda";
|
|
reg = <0x0 0x70030000 0x0 0x10000>;
|
|
interrupts = <GIC_SPI 81 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&tegra_car TEGRA124_CLK_HDA>,
|
|
<&tegra_car TEGRA124_CLK_HDA2HDMI>,
|
|
<&tegra_car TEGRA124_CLK_HDA2CODEC_2X>;
|
|
clock-names = "hda", "hda2hdmi", "hda2codec_2x";
|
|
resets = <&tegra_car 125>, /* hda */
|
|
<&tegra_car 128>; /* hda2hdmi */
|
|
<&tegra_car 111>, /* hda2codec_2x */
|
|
reset-names = "hda", "hda2hdmi", "hda2codec_2x";

};
