This patch series based on v4.13-rc1, include i2c binding file information
formats modification, MT7622 i2c dt-binding and compatible.
changes since v3:
- Split the formats modification into another patch
changes since v2:
- Remove all the length settings from mt7622_i2c_quirks
changes since v1:
- Modify commit message
- Revise dt-binding documentation
Jun Gao (3):
dt-bindings: i2c: modify information formats
dt-bindings: i2c: Add MediaTek MT7622 i2c binding
i2c: mediatek: Add i2c compatible for MediaTek MT7622
