7title: NXP Bluetooth chips
8
9description:
10  This binding describes UART-attached NXP bluetooth chips. These chips
11  are dual-radio chips supporting WiFi and Bluetooth. The bluetooth
12  works on standard H4 protocol over 4-wire UART. The RTS and CTS lines
13  are used during FW download. To enable power save mode, the host
14  asserts break signal over UART-TX line to put the chip into power save
15  state. De-asserting break wakes up the BT chip.
