    Subject[PATCH v2 1/2] dt-bindings: leds: Add bindings for Intel LGM SoC
    Date
    Add DT bindings YAML schema for SSO controller driver
    of Lightning Mountain (LGM) SoC.

    Signed-off-by: Amireddy Mallikarjuna reddy <mallikarjunax.reddy@linux.intel.com>
    ---
    v1:
    - Initial version

    v2:
    - Fix bot errors (wrong indentation).
    - Spell out LGM and SSO.
    - Remove vendor specific name for LED properites.
    - removed deprecating property "label"
    - Include 'reg', 'function' & 'color' properties.
