charset="utf-8" Convert the Texas Instruments TWL6040 audio codecs family bindings to DT schema. During the conversion, the following updates were made: - Changed 'twl6040,audpwron-gpio' to 'ti,audpwron-gpio', which was misnamed in the old txt binding. - Made 'gpio-controller', '#gpio-cells', and 'ti,audpwron-gpio' optional because modern platforms do not require them. - Renamed the vibra 'vddvibl_uV'/'vddvibr_uV' properties to 'ti,vddvibl-uV'/'ti,vddvibr-uV', the names actually read by the twl6040-vibra driver. - Required 'vddvibl-supply' and 'vddvibr-supply' when the 'vibra' child node is present, since the twl6040-vibra driver unconditionally requests both. Signed-off-by: Eduard Bostina Reviewed-by: Rob Herring (Arm) --- Changes in v4: - Add blank lines between the vibra child node's properties for readability, as requested in review. No functional change.
