-Subject: [PATCH] net: phy: at803x: Request 'reset' GPIO only for AT8030 PHY
-
-This removes the dependency on GPIOLIB for non faulty PHYs.
-
-Indeed, without this patch, if GPIOLIB is not selected
-devm_gpiod_get_optional() will return -ENOSYS and the driver probe
-call will fail, regardless of the actual PHY hardware.
-
-Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
-only AT8030 presents the issues that commit 13a56b449325 ("net: phy:
-at803x: Add support for hardware reset") attempts to work-around by
-using a 'reset' GPIO line.
-
-Hence, only AT8030 should depend on GPIOLIB operating properly.
-
-Fixes: 13a56b449325 ("net: phy: at803x: Add support for hardware reset")
