[PATCH v2 0/3] Bluetooth: hci_qca: add support for QCA9377

[Christian Hewitt]

From: Christian Hewittt <christianshewitt@gmail.com>

This series adds a new compatible for the QCA9377 BT device that is found
in many Android TV box devices, makes minor changes to allow max-speed
values for the device to be read from device-tree, and updates bindings
to reflect those changes.

v2 changes: rebase against bluetooth-next

[PATCH v2 2/3] Bluetooth: hci_qca: add compatible for QCA9377

[Christian Hewitt]

Add a compatible so QCA9377 devices can be defined in device-tree.

[PATCH v2 3/3] Bluetooth: hci_qca: allow max-speed to be set for QCA9377 devices

[Christian Hewitt]

Move the read of max-speed from device-tree out of the qca_is_wcn399x
if block so oper_speed can be set for QCA9377 devices as well.
