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

[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"

[PATCH v2 2/4] Bluetooth: btqca: Add WCN3988 support

[Luca Weiss]

Add support for the Bluetooth chip codenamed APACHE which is part of
WCN3988.

The firmware for this chip has a slightly different naming scheme
compared to most others. For ROM Version 0x0200 we need to use
apbtfw10.tlv + apnv10.bin and for ROM version 0x201 apbtfw11.tlv +
apnv11.bin

The device has a WCN3988 chip for WiFi and Bluetooth. Configure the
Bluetooth node and enable the UART it is connected to, plus the
necessary pinctrl that has been borrowed with comments from
sc7280-idp.dtsi.

Just to be sure, patches 1-2 shall be applied to bluetooth-next the
