Convert the legacy TXT binding for the OMAP TWL4030 sound card to the modern YAML DT schema format. This adds formal validation and improves documentation. Acked-by: Mark Brown <broonie@kernel.org> Signed-off-by: Jihed Chaibi <redacted> --- Changes in v3: - No change to binding content, only updating commit message format. Changes in v2: - Fixed comment formatting (added spaces for better alignment). - Updated commit subject to align with subsystem style. - Retained Acked-by from v1 as changes are cosmetic. --- .../bindings/sound/omap-twl4030.txt | 62 ----------- .../bindings/sound/ti,omap-twl4030.yaml | 102 ++++++++++++++++++ 2 files changed, 102 insertions(+), 62 deletions(-) delete mode 100644 Documentation/devicetree/bindings/sound/omap-twl4030.txt create mode 100644 Documentation/devicetree/bindings/sound/ti,omap-twl4030.yaml
