So I wonder if it isn't better to use standby-gpios instead of silent-gpios? I am looking at FRDM-IMX91 schematic file SPF-94610_A1.pdf. But on the other hand we have static const struct can_transceiver_data tja1051_drvdata =3D { =C2=BB .flags =3D CAN_TRANSCEIVER_SILENT_PRESENT | CAN_TRANSCEIVER_EN= _PRESENT, }; So TJA1051 is not advertised as having a stdby flag.
