| Series | [v2,1/2] bluetooth: btnxpuart: Support for controller wakeup gpio config | expand |
Hi Loic, I am okay with this DT patch for adding nxp,wakein-pin and nxp,wakeout-pin.

NXP bluetooth controller may have GPIO pins used and routed for `WAKE_IN` and `WAKE_OUT`, such pin info must be known so that the driver is can configure the controller's firmware accordingly.
