Subject: [PATCH 120/224] soc: mediatek: pwrap: add MediaTek MT6380 as one
|
|
slave of pwrap
|
|
|
|
Add MediaTek MT6380 regulator becoming one of PMIC wrapper slave
|
|
and also add extra new regmap_config of 32-bit mode for MT6380
|
|
since old regmap_config of 16-bit mode can't be fit into the need.
