From bc0500c1e43d95cca5352d2345fb0769f314ba22 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Thu, 3 Oct 2019 15:32:12 +0300 Subject: device property: Add fwnode_get_name for returning the name of a node The fwnode framework did not have means to obtain the name of a node. Add that now, in form of the fwnode_get_name() function and a corresponding get_name fwnode op. OF and ACPI support is included.
