   1 * Marvell Armada 7K/8K PCIe interface
   2
   3 This PCIe host controller is based on the Synopsis Designware PCIe IP
   4 and thus inherits all the common properties defined in designware-pcie.txt.
   5
   6 Required properties:
   7 - compatible: "marvell,armada8k-pcie"
   8 - reg: must contain two register regions
   9    - the control register region
  10    - the config space region
  11 - reg-names:
  12    - "ctrl" for the control register region
  13    - "config" for the config space region
  14 - interrupts: Interrupt specifier for the PCIe controler
  15 - clocks: reference to the PCIe controller clock
