Subject: [PATCH v2 0/5] Add support for Qualcomm QCA639x chips family

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 share common power sources wich should be turned on
before either of devices can be probed. Declare common 'qca639x' driver
providing a power domain to be used by both BT and WiFi parts.

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.
