Subject: [PATCH 3/6] soc: mediatek: pwrap: Add support for MT6735 and MT6328 SoC/PMIC pair
From: Yassine Oudjana <y.oudjana@...tonmail.com>
Add register definitions and configuration for the MT6735 SoC and the
MT6328 PMIC which are commonly paired and communicate through the PMIC
wrapper.
Note that the PMIC wrapper on MT6735M has a slightly different register
map and is therefore NOT compatible with MT6735.
