[PATCH v6 00/33] staging: mt7621-pci: Parse ports info from DT and other minor cleanups

[Sergio Paracuellos <sergio.paracuellos@gmail.com>]

This patch series parse remaining port info from device tree storing
it in mt7621_pcie_port struct created for this. It also performs a lot
of cleanups to get the driver in a good shape to give it a try to get
mainlined. All of this changes are only compile-tested.

Cleanups performed here:
    - Style cleanups.
    - Use PERST_N instead of GPIO control.
    - Remove not used macros.
    - Use kernel reset_control functions.
    - Remove unused code.

Changes in v6:
    - PATCHES 18-33 added:
        * Review defines and macros and create some news to get code more
          readable.
        * Avoid globals.
        * Factor out new 'mt7621_pcie_enable_port' and 'mt7621_pcie_enable_ports'
          functions.
        * Use PERST_N instead of GPIO control.
        * Use msleep instead of mdelay.
    - Rebased onto staging-next

Changes in v5:
    - Patch 18 removed from the series. Already submited by Mamta Shukla (also applied)
    - Rebased onto staging-next

Changes in v4:
    - Some patches of this series was previously added to staging.
    - Rebased onto staging-next.

Changes in v3:
    - 'mt7621_pcie_enable_port' now returns an error instead of void
      to avoid a layering violation.
    - Delete 'mt7621_pcie_port_free' function and just delete
      port from the list in probe function.
    - Use parent node to get base address registers for each port.

Changes in v2:
    - Rewrite phy part of the driver
    - fix some checkpatch complains
    - make use of sysctl from DT

Hope this helps.

Best regards,
    Sergio Paracuellos
