[PATCH v2 2/2] soc: mediatek: pm-domains: Add support for MT6735
From: Yassine Oudjana
Date: Thu Mar 02 2023 - 07:27:49 EST
From: Yassine Oudjana <y.oudjana@xxxxxxxxxxxxxx>
Add support for SCPSYS power domains of MT6735. All non-CPU power domains
are added except for MD2 (C2K modem), which is left out due to issues
with powering it on.
Signed-off-by: Yassine Oudjana <y.oudjana@xxxxxxxxxxxxxx>
