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.
