From: Thierry Reding <treding@xxxxxxxxxx> Convert the NVIDIA embedded controller bindings from the free-form text format to json-schema. Acked-by: Marc Dietrich <marvin24@xxxxxx> Signed-off-by: Thierry Reding <treding@xxxxxxxxxx> --- Changes in v3: - rename node to i2c to clarify that it's a repurposed I2C controller - drop unused #address-cells and #size-cells Changes in v2: - drop $ref for standard clock-frequency property - use 4 spaces for indentation in example - move to soc/tegra directory --- .../bindings/arm/tegra/nvidia,nvec.txt | 21 ----- .../bindings/soc/tegra/nvidia,nvec.yaml | 84 +++++++++++++++++++ 2 files changed, 84 insertions(+), 21 deletions(-) delete mode 100644 Documentation/devicetree/bindings/arm/tegra/nvidia,nvec.txt create mode 100644 Documentation/devicetree/bindings/soc/tegra/nvidia,nvec.yaml diff --git a/Documentation/devicetree/bindings/arm/tegra/nvidia,nvec.txt b/Documentation/devicetree/bindings/arm/tegra/nvidia,nvec.txt deleted file mode 100644 index 5ae601e7f51f..000000000000 --- a/Documentation/devicetree/bindings/arm/tegra/nvidia,nvec.txt +++ /dev/null @@ -1,21 +0,0 @@ -NVIDIA compliant embedded controller - -Required properties: -- compatible : should be "nvidia,nvec". -- reg : the iomem of the i2c slave controller -- interrupts : the interrupt line of the i2c slave controller -- clock-frequency : the frequency of the i2c bus -- gpios : the gpio used for ec request -- slave-addr: the i2c address of the slave controller -- clocks : Must contain an entry for each entry in clock-names. - See ../clocks/clock-bindings.txt for details. -- clock-names : Must include the following entries: - Tegra20/Tegra30: - - div-clk - - fast-clk - Tegra114: - - div-clk -- resets : Must contain an entry for each entry in reset-names. - See ../reset/reset.txt for details. -- reset-names : Must include the following entries: - - i2c diff --git a/Documentation/devicetree/bindings/soc/tegra/nvidia,nvec.yaml b/Documentation/devicetree/bindings/soc/tegra/nvidia,nvec.yaml new file mode 100644 index 000000000000..d5261ce3a619 --- /dev/null +++ b/Documentation/devicetree/bindings/soc/tegra/nvidia,nvec.yaml @@ -0,0 +1,84 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/soc/tegra/nvidia,nvec.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: NVIDIA compliant embedded controller + +maintainers: + - Thierry Reding <thierry.reding@xxxxxxxxx> + - Jon Hunter <jonathanh@xxxxxxxxxx> + +properties: + compatible: + const: nvidia,nvec + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + clocks: + minItems: 1 + items: + - description: divider clock + - description: fast clock + + clock-names: + minItems: 1 + items: + - const: div-clk + - const: fast-clk + + resets: + items: + - description: module reset + + reset-names: + items: + - const: i2c + + clock-frequency: true + + request-gpios: + description: phandle to the GPIO used for EC request + + slave-addr: + $ref: /schemas/types.yaml#/definitions/uint32 + description: I2C address of the slave controller + +additionalProperties: false + +required: + - compatible + - reg + - interrupts + - clocks + - clock-names + - resets + - reset-names + - clock-frequency + - request-gpios + - slave-addr + +examples: + - | + #include <dt-bindings/clock/tegra20-car.h> + #include <dt-bindings/gpio/tegra-gpio.h> + #include <dt-bindings/interrupt-controller/arm-gic.h> + + i2c@7000c500 { + compatible = "nvidia,nvec"; + reg = <0x7000c500 0x100>; + interrupts = <GIC_SPI 92 IRQ_TYPE_LEVEL_HIGH>; + clock-frequency = <80000>; + request-gpios = <&gpio TEGRA_GPIO(V, 2) GPIO_ACTIVE_HIGH>; + slave-addr = <138>; + clocks = <&tegra_car TEGRA20_CLK_I2C3>, + <&tegra_car TEGRA20_CLK_PLL_P_OUT3>; + clock-names = "div-clk", "fast-clk"; + resets = <&tegra_car 67>; + reset-names = "i2c"; + }; -- 2.41.0
