FWIW:

Tested-by: Tyler Baker <tyler.baker@...aro.org>

This whole series on top of v4.11-rc7, with the addition of the iMX7
GPCv2 and reset driver. Tested on a imx7d-cl-som with a CUK Killer
Doubleshot Wireless-AC 1535 wlan/bt radio using a mini pcie to m2
adapter. Confirmed that the radio was able to associate with an AP
using WPA2, and connected to multiple devices using 6lowpan over BLE.
