+title: NXP Bluetooth chips
+
+description:
+ This binding describes UART-attached NXP bluetooth chips.
+ These chips are dual-radio chips supporting WiFi and Bluetooth.
+ The bluetooth works on standard H4 protocol over 4-wire UART.
+ The RTS and CTS lines are used during FW download.
+ To enable power save mode, the host asserts break signal
+ over UART-TX line to put the chip into power save state.
+ De-asserting break wakes-up the BT chip.
The verb is spelled with a space: wakes up the BT chip.
You seem to break the line whenever a sentence ends. Is that intentional?
