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 Tegra114 SPI controller.
|
|
|
|
Required properties:
|
|
- compatible : For Tegra114, must contain "nvidia,tegra114-spi".
|
|
Otherwise, must contain '"nvidia,<chip>-spi", "nvidia,tegra114-spi"' where
|
|
<chip> is tegra124, tegra132, or tegra210.
|
|
- reg: Should contain SPI registers location and length.
|
|
- interrupts: Should contain SPI interrupts.
|
|
- clock-names : Must include the following entries:
|
|
- spi
|
|
- resets : Must contain an entry for each entry in reset-names.
|
|
See ../reset/reset.txt for details.
|
|
- reset-names : Must include the following entries:
|
|
- spi
|
|
- dmas : Must contain an entry for each entry in clock-names.
|
|
See ../dma/dma.txt for details.
|
|
- dma-names : Must include the following entries:
|
|
- rx
|
|
- tx
|
|
- clocks : Must contain an entry for each entry in clock-names.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
|
|
Recommended properties:
|
|
- spi-max-frequency: Definition as per
|
|
Documentation/devicetree/bindings/spi/spi-bus.txt
|
|
Example:
|
|
|
|
spi@7000d600 {
|
|
compatible = "nvidia,tegra114-spi";
|
|
reg = <0x7000d600 0x200>;
|
|
interrupts = <0 82 0x04>;
|
|
spi-max-frequency = <25000000>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
clocks = <&tegra_car 44>;
|
|
clock-names = "spi";
|
|
resets = <&tegra_car 44>;
|
|
reset-names = "spi";
|
|
dmas = <&apbdma 16>, <&apbdma 16>;
|
|
dma-names = "rx", "tx";
|
|
status = "disabled";
