[PATCH 3/6] phy: qcom-qmp-usbc: Use register definitions in qserdes-txrx-v3
From: Shawn Guo
Date: Sat Mar 14 2026 - 01:15:00 EST
The register definitions in header qserdes-txrx-v2 and qserdes-txrx-v3
are actually identical. Considering that QSERDES TX/RX v2 is already
defined by header qserdes-txrx, qserdes-txrx-v2 is really just
a duplication of qserdes-txrx-v3 for QSERDES TX/RX v3. Switch
qcom-qmp-usbc driver to use v3 registers.
