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.
