From 40ba6a12a5488e0fbcfae2f21a4f62bdb02d44d3 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 13 Sep 2019 15:55:47 -0700 Subject: net: mdio: switch to using gpiod_get_optional() The MDIO device reset line is optional and now that gpiod_get_optional() returns proper value when GPIO support is compiled out, there is no reason to use fwnode_get_named_gpiod() that I plan to hide away. Let's switch to using more standard gpiod_get_optional() and gpiod_set_consumer_name() to keep the nice "PHY reset" label. Also there is no reason to only try to fetch the reset GPIO when we have OF node, gpiolib can fetch GPIO data from firmwares as well.
