While adding support for the PCIe EP mode support to the QMP driver I
couldn't help but notice that the QMP PHY driver has slowly become the a
beast with tons of conditions and corner cases being inserted here and
there.r
This an RFC for an attempt to to cleanup the QMP driver by splitting the
QMP PHY driver into five smaller drivers, each targeting a particular
family of PHY backends (DP/combo, PCIe, UFS, USB and a separate driver
for the MSM8996 PCIe PHY). Yes, this results in some code duplication,
but I hope that the end result is still better than the current
situation.
Changes since RFC v2:
- After dicussion with Vinod, revert back to the approach from RFC v1:
copy the source and clean it up rather than creating new drivers from
the blank space. This lowers the risc of breaking any of the platforms.
- Drop common phy-qcom-qmp-lib.c for now. The goal of this patchseries
is to be merged early during the development cycle to unblock further
QMP driver development. Additional cleanups and code unification can
come up later.
Changes since RFC v1:
- Split the patchset to be able to get through the email size
limitations
- Minor correcions to the split drivers
