Signed-off-by: Min Guo Reviewed-by: Rob Herring --- changes in v8: 1. Add reviewed by Rob changes in v7: 1. Modify compatible as - compatible : should be one of: "mediatek,mt2701-musb" ... followed by "mediatek,mtk-musb" 2. Change usb connector child node compatible as "gpio-usb-b-connector" changes in v6: 1. Modify usb connector child node changes in v5: suggested by Rob: 1. Modify compatible as - compatible : should be one of: "mediatek,mt-2701" ... followed by "mediatek,mtk-musb" 2. Add usb connector child node changes in v4: suggested by Sergei: 1. String alignment changes in v3: 1. no changes changes in v2: suggested by Bin: 1. Modify DRC to DRD suggested by Rob: 2. Drop the "-musb" in compatible 3. Remove phy-names 4.
