[PATCH v3 2/4] phy: qualcomm: qmp-combo: Update DP PHY common init tables
From: Nabige Aala
Date: Fri Aug 28 2026 - 05:48:14 EST
From: Ritesh Kumar <ritesh.kumar@xxxxxxxxxxxxxxxx>
Update common DP PHY serdes and TX initialization tables with
corrected PLL control values (MODE0 instead of MODE1), updated
SSC step size, reset control, and various TX lane configuration
parameters including emphasis levels and driver enable settings.
