| H A D | at803x.c | 9eb13f65 Wed Mar 23 05:49:09 CDT 2016 Sebastian Frias <sf84@laposte.net> 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")
