    PCI: designware: Split Exynos and i.MX bindings · 1db823ee
    Lucas Stach authored
    The glue around the core designware IP is significantly different between
    the Exynos and i.MX implementation, which is reflected in the DT bindings.
    
    This changes the i.MX6 binding to reuse as much as possible from the common
    designware binding and removes old cruft.
    
    I removed the optional GPIOs with the following reasoning:
    - disable-gpio: endpoint specific GPIO, not currently wired up in any code.
      Should be handled by the PCI device driver, not the host controller
      driver.
    - wake-up-gpio: same as above.
    - power-on-gpio: No user in any upstream DT.  This should be handled by a
      regulator which shouldn't be controlled by the host driver, but rather by
      the PCI device driver.
