QCA WLAN Driver
---------------

This driver adds support for the WLAN subsystem for supporting
integrated WLAN module

  - reg = <baseaddr length>
  - interrupts = <list of msi and legacy interrupts>
  - interrupt-names = <list of interrupt's string name defined in the interrupts field. Please
    ensure the order of the interrupts and the interrupts name matches with each other.
  - wlan-en-gpio: WLAN_EN GPIO signal specified by the chip specifications
  - pinctrl-names: Names corresponding to the numbered pinctrl states
  - pinctrl-<n>: Pinctrl states as described in
                 bindings/pinctrl/pinctrl-bindings.txt
  - qcom,bdf-addr: BDF address corresponding to the memory profile
  - qcom,caldb-addr: caldb address corresponding to the memory profile
  - qcom,caldb-size: caldb size
  - qcom,userpd-subsys-name: userpd name in case multi-pd arch is enabled
  - status = ok or disabled.
