Just for clarification GPIO 23 is connected to a pin named CAN_STBY.
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 = {
»       .flags = CAN_TRANSCEIVER_SILENT_PRESENT | CAN_TRANSCEIVER_EN_PRESENT,
};

So TJA1051 is not advertised as having a stdby flag.
