Hello Dan, > +Required properties: [...] > + - device-wake-gpios: Wake up GPIO to wake up the TCAN device. > + - device-state-gpios: Input GPIO that indicates if the device is in > + a sleep state or if the device is active. If I understand the driver code correctly, device-wake-gpios and device-state-gpios are optional properties, not required? I'm currently designing a 4xTCAN4550 raspi hat, would be good to know whether a wake circuit is a must or not, and how the device-state-gpios should be fed, if really needed. Cheers, Hubert
