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. 16 17maintainers: 18 - Neeraj Sanjay Kale <neeraj.sanjaykale@nxp.com> 19 20properties: 21 compatible: 22 enum: 23 - nxp,88w8987-bt 24 - nxp,88w8997-bt 25 26 fw-init-baudrate: 27 description: 28 Chip baudrate after FW is downloaded and initialized. 29 This property depends on the module vendor's 30 configuration.
