This patch adds a driver for NXP bluetooth chipsets.

The driver is based on H4 protocol, and uses serdev APIs. It supports host
to chip power save feature, which is signalled by the host by asserting
break over UART TX lines, to put the chip into sleep state.

To support this feature, break_ctl has also been added to serdev-tty along
with a new serdev API serdev_device_break_ctl().

This driver is capable of downloading firmware into the chip over UART.

The document specifying device tree bindings for this driver is also
included in this patch series.

Neeraj Sanjay Kale (4):
  serdev: Replace all instances of ENOTSUPP with EOPNOTSUPP
  serdev: Add method to assert break signal over tty UART port
  dt-bindings: net: bluetooth: Add NXP bluetooth support
  Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets

If there are no new comments to be addressed by the end of the day I'm
planning to merge this into bluetooth-next.

FWIIW, as someone involved in the review of this series, I am fine with that.
Even though I have only supplied tags for some of the patches;
those for which I feel that it is appropriate.
