[PATCH v2 0/4] Add WCN3988 Bluetooth support for Fairphone 4

[Luca Weiss]

Add support in the btqca/hci_qca driver for the WCN3988 and add it to
the sm7225 Fairphone 4 devicetree.

Devicetree patches go via Qualcomm tree, the rest via their respective
trees.

Previously with the RFC version I've had problems before with Bluetooth
scanning failing like the following:

  [bluetooth]# scan on
  Failed to start discovery: org.bluez.Error.InProgress

  [  202.371374] Bluetooth: hci0: Opcode 0x200b failed: -16

This appears to only happen with driver built-in (=y) when the supported
local commands list doesn't get updated in the Bluetooth core and
use_ext_scan() returning false. I'll try to submit this separately since
this now works well enough with =m. But in both cases (=y, =m) it's
behaving a bit weirdly before (re-)setting the MAC address with "sudo
btmgmt public-addr fo:oo:ba:ar"
