- Subject: [PATCH 15/16] i2c: mediatek: add support for MT7981 SoC
- Add support for the I2C units found in the MediaTek MT7981 and MT7988
- SoCs. Just like other recent MediaTek I2C units that also uses v3
- register offsets (which differ from v2 only by OFFSET_SLAVE_ADDR being
- 0x94 instead of 0x4).
