Subject: [PATCH v4 00/16] phy: qcom-qmp-pcie: add support for sc8280xp

This series adds support for the PCIe PHYs on SC8280XP including its
four-lane PHYs.

The first half of the series clean up the driver in preparation for
supporting SC8280XP and its new devicetree bindings that drops the
legacy child node and the (incomplete) description of register
subregions.

The other QMP bindings suffer from similar problems and follow-on series
will do corresponding changes to the UFS, USB and combo QMP bindings and
drivers.

Note that these patches depend on the linux-phy next branch of today.

Johan


Changes in v4
 - break out switch to shorter tables identifier in a preparatory patch
   (Vinod)

Changes in v3
 - use bulk clk API for pipe clocks (Dmitry)

Changes in v2
 - rename current DT schema after first SoC added to the original
   bindings (IPQ8074) and add a reference to the new SC8280XP bindings
   instead of marking the current bindings as "legacy" (Krzysztof)

 - add "sc8280xp" infix to the new DT schema filename (Krzysztof)

 - tighten description of the 'qcom,4ln-config-sel' phandle array
   (Krzysztof)
