Thanks for confirming this,I will add this to the commit message and
fallback to sa8775 then.
I am curious, do the PHY QUIRKs in dsi_phy_7nm.c reflect PHY revision?
I notice
REG_DSI_7nm_PHY_CMN_REVISION_ID0 QUIRK
SM8250: 0x00000014 4.1
SM8650: 0x00000025 5.2
SC8280XP: 0x00000024 4.2
SM8750: 0x00000027 7.0(*)
(*) SM8750 is 7.2 in the downstream.
Best wishes,
Pengyu
