[PATCH v2 2/2] phy: qcom-qmp-usb: split PCS_USB init table for sc8280xp and sa8775p

Mon Aug 28 08:23:51 PDT 2023


For sc8280xp and sa8775p, PCS and PCS_USB initialization data is
described in the same table, thus the pcs_usb offset is not being
applied during initialization of PCS_USB registers. Fix this by adding
the appropriate pcs_usb_tbl tables.

Fixes: 8bd2d6e11c99 ("phy: qcom-qmp: Add SA8775P USB3 UNI phy")
Fixes: c0c7769cdae2 ("phy: qcom-qmp: Add SC8280XP USB3 UNI phy")
