Series usb: typec: qcom-pmic-typec: enable support for PMI632 PMIC | expand

Commit Message

Dmitry Baryshkov Jan. 13, 2024, 5:42 a.m. UTC 
Rework Qualcomm PMIC TCPM driver to allow different platform-specific
implementations of the PD PHY interface. While majority of platforms
has the same of register for the PD PHY, some obscure ones (PMI632) do
not have real PD PHY support. Add proper interface between the main
module and the PD PHY backend to allow switching the PD PHY
implementation.
