These chips 1162306a36Sopenharmony_ci are dual-radio chips supporting WiFi and Bluetooth. The bluetooth 1262306a36Sopenharmony_ci works on standard H4 protocol over 4-wire UART. The RTS and CTS lines 1362306a36Sopenharmony_ci are used during FW download. To enable power save mode, the host 1462306a36Sopenharmony_ci asserts break signal over UART-TX line to put the chip into power save 1562306a36Sopenharmony_ci state. De-asserting break wakes up the BT chip. 1662306a36Sopenharmony_ci 1762306a36Sopenharmony_cimaintainers: 1862306a36Sopenharmony_ci - Neeraj Sanjay Kale <neeraj.sanjaykale@nxp.com> 1962306a36Sopenharmony_ci 2062306a36Sopenharmony_ciproperties: 2162306a36Sopenharmony_ci compatible: 2262306a36Sopenharmony_ci enum: 2362306a36Sopenharmony_ci - nxp,88w8987-bt 2462306a36Sopenharmony_ci - nxp,88w8997-bt 2562306a36Sopenharmony_ci 2662306a36Sopenharmony_ci fw-init-baudrate: 2762306a36Sopenharmony_ci $ref: /schemas/types.yaml#/definitions/uint32 2862306a36Sopenharmony_ci default: 115200 2962306a36Sopenharmony_ci description: 3062306a36Sopenharmony_ci Chip baudrate after FW is downloaded and initialized. 3162306a36Sopenharmony_ci This property depends on the module vendor's 3262306a36Sopenharmony_ci configuration. 3362306a36Sopenharmony_ci 3462306a36Sopenharmony_cirequired: 3562306a36Sopenharmony_ci - compatible 3662306a36Sopenharmony_ci 3762306a36Sopenharmony_ciadditionalProperties: false 3862306a36Sopenharmony_ci 3962306a36Sopenharmony_ciexamples: 4062306a36Sopenharmony_ci - | 4162306a36Sopenharmony_ci serial { 4262306a36Sopenharmony_ci bluetooth { 4362306a36Sopenharmony_ci compatible = "nxp,88w8987-bt"; 4462306a36Sopenharmony_ci fw-init-baudrate = <3000000>; 4562306a36Sopenharmony_ci }; 4662306a36Sopenharmony_ci }; 47
