Subject: [PATCH v2] drm/msm/dsi: use the correct VREG_CTRL_1 value for 4nm cphy
Date: Thu, 9 Nov 2023 19:02:14 -0500 [thread overview]
Message-ID: <20231110000216.29979-1-jonathan@marek.ca> (raw)
Use the same value as the downstream driver. This change is needed for CPHY
mode to work correctly.
Fixes: 8b034e6771113 ("drm/msm/dsi: add support for DSI-PHY on SM8550")
