Convert NVIDIA Tegra30 I2S binding to DT schema and add "clock-names" property used by multiple tegra i2s blocks in arch/arm64/boot/dts/nvidia/tegra132.dtsi. This is not a required property by the binding. Signed-off-by: Mohammad Shehar Yaar Tausif <sheharyaar48@xxxxxxxxx> --- Changes v3->v4: - removed redundant example - defined clock-names property v3: https://lore.kernel.org/all/20240425090716.176818-1-sheharyaar48@xxxxxxxxx/ --- .../bindings/sound/nvidia,tegra30-i2s.txt | 27 ------ .../bindings/sound/nvidia,tegra30-i2s.yaml | 83 +++++++++++++++++++ 2 files changed, 83 insertions(+), 27 deletions(-) delete mode 100644 Documentation/devicetree/bindings/sound/nvidia,tegra30-i2s.txt create mode 100644 Documentation/devicetree/bindings/sound/nvidia,tegra30-i2s.yaml diff --git a/Documentation/devicetree/bindings/sound/nvidia,tegra30-i2s.txt b/Documentation/devicetree/bindings/sound/nvidia,tegra30-i2s.txt deleted file mode 100644 index 38caa936f6f8..000000000000 --- a/Documentation/devicetree/bindings/sound/nvidia,tegra30-i2s.txt +++ /dev/null @@ -1,27 +0,0 @@ -NVIDIA Tegra30 I2S controller - -Required properties: -- compatible : For Tegra30, must contain "nvidia,tegra30-i2s".
