Signed-off-by: Loys Ollivier --- v3: Removed the I2C and SPI interfaces references. Removed the "mediatek,mt3339" compatible line. Added the optional propertied (reset, fix) Added the pin names for the optional properties. v2: Renamed bindings from Globaltop/gtop to Mediatek/mtk. Moved current-speed as an optional propertie. Removed the status line in the example.
