Subject: [PATCH v3 1/2] dt-bindings: leds: Add bindings for Intel LGM SoC
Date: Thu, 10 Dec 2020 17:12:11 +0800 [thread overview]
Message-ID: <49ebc8e27958cb77cde36e5f95ad530803259907.1607591119.git.mallikarjunax.reddy@linux.intel.com> (raw)
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.
v3:
- Included full names(maintainers).
- changed compatible SoC specific.
- Remove redundant properties.
- Updated vendor prefix and unit suffix to properties.
