Hi Sudip, why do we carry if (pcidev->vendor != PCI_VENDOR_ID_EXAR) return -ENODEV; in gpio_exar_probe? This effectively prevents that EXAR_DEVICE(COMMTECH, COMMTECH_4222PCIE, pbn_exar_XR17V35x), EXAR_DEVICE(COMMTECH, COMMTECH_4224PCIE, pbn_exar_XR17V35x), EXAR_DEVICE(COMMTECH, COMMTECH_4228PCIE, pbn_exar_XR17V35x), gain GPIO support. Do those devices lack access to the pins? Or can we drop the filter. I don't have access to those devices, just wondering because the code is not explaining the reason.
Same here. I do not have these devices and have no idea if they support the gpio pins or not.
