From e160f7d430f163bc42757aff3bf2bcac0a459f02 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 17 Jan 2017 16:52:55 -0700 Subject: dm: core: Replace of_offset with accessor At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.
