    Subject[PATCH v2 09/15] dt-bindings: phy: qcom,qmp-pcie: rename current bindings
    Date
    The current QMP PCIe PHY bindings are based on the original MSM8996
    binding which provided multiple PHYs per IP block and these in turn were
    described by child nodes.

    Later QMP PCIe PHY blocks only provide a single PHY and the remnant
    child node does not really reflect the hardware.

    The original MSM8996 binding also ended up describing the individual
    register blocks as belonging to either the wrapper node or the PHY child
    nodes.

    This is an unnecessary level of detail which has lead to problems when
    later IP blocks using different register layouts have been forced to fit
    the original mould rather than updating the binding. The bindings are
    arguable also incomplete as they only the describe register blocks used
    by the current Linux drivers (e.g. does not include the per lane PCS
    registers).

    In preparation for adding new bindings for SC8280XP which further
    bindings can be based on, rename the current schema file after IPQ8074,
    which was the first SoC added to the bindings after MSM8996 (which has
    already been split out), and add a reference to the SC8280XP bindings.
