[PATCH v4 0/3] Add i2c dt-binding and compatible for Mediatek MT7622 SoC

[Jun Gao]

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

[PATCH v4 2/3] dt-bindings: i2c: Add MediaTek MT7622 i2c binding

[Jun Gao]

From: Jun Gao <jun.gao@mediatek.com>

Add MT7622 i2c binding to binding file. Compare to MT8173 i2c
controller, MT7622 limits message numbers to 255, and does not
support 4GB DMA mode.
