+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.
