From 9dc23cba0927d09cb481da064c8413eb9df42e2b Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Thu, 28 Mar 2024 09:02:45 +0100 Subject: drm/msm/adreno: Set highest_bank_bit for A619 The default highest_bank_bit of 15 didn't seem to cause issues so far but downstream defines it to be 14. But similar to [0] leaving it on 14 (or 15 for that matter) causes some corruption issues with some resolutions with DisplayPort, like 1920x1200. So set it to 13 for now so that there's no screen corruption.
