From a264d10ff45c688293d9112fddd8d29c819e0853 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 9 Jan 2017 16:02:28 +0200 Subject: gpiolib: Convert fwnode_get_named_gpiod() to configure GPIO Make fwnode_get_named_gpiod() consistent with the rest of gpiod_get() like API, i.e. configure GPIO pin immediately after request. Besides obvious clean up it will help to configure pins based on firmware provided resources.
