Qualcomm QCA639x is a family of WiFi + Bluetooth chips, with BT part
being controlled through the UART and WiFi being present on PCIe
bus. Both blocks use common power management unit wich should be turned
on before either of devices can be probed. Add common 'qcom-qca6390'
driver providing regulator to be used by both BT and PCIe parts.

Changes since v2:
 - Rebase on top of linux-next to get wcn6750 changes.
 - Switch from misc device providing power domains into regulator code.
 - Use vddpe-3v3-supply as expected by pcie-qcom driver.
 - Use enable_gpio functionality in hci_qca driver.

Changes since v1:
 - Stopped using wildcard in the dts binding, stick to qcom,qca6390.
 - Stopped using pcie0_phy for qca639x power domain.
 - Describe root PCIe bridge in the dts and bind power domain to the
   bridge.
 - Add pci quirk to power up power domains connected to this bridge.

Dmitry Baryshkov (7):
      dt-bindings: regulator: qcom,qca6390: add binding for QCA6390 device
      regulator: qca6390: add support for QCA639x powerup sequence
      Bluetooth: hci_qca: provide default device data
      Bluetooth: hci_qca: merge qca_power into qca_serdev
      Bluetooth: hci_qca: merge wcn & non-wcn code paths
      Bluetooth: hci_qca: add power sequencer support to qca6390
      arm64: dts: qcom: qrb5165-rb5: add QCA6391 WiFi+BT SoC
