[PATCH 0/4] Add support for Qualcomm QCA639x chips family

[Dmitry Baryshkov]

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.
