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).
