From 43c4d44e3330fd21679c0790fa2176075d0e69bf Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 6 Apr 2016 12:49:19 -0600 Subject: fdt: implement dev_get_addr_name() This function parses the reg property based on an index found in the reg-names property. This is required for bindings that are written using reg-names rather than hard-coding indices in reg.
