From 46c4b64516d54d149a3050c29e3ca06842f609b3 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 19 Mar 2013 13:46:40 +0200 Subject: [PATCH] OMAPDSS: SDI: fix regulators for DT SDI requires a regulator to operate. This regulator is, for some reason, currently attached to the virtual omapdss device, instead of the SDI device. This does not work for DT, as the regulator mappings need to be described in the DT data, and the virtual omapdss device is not present there. Fix the issue by acquiring the regulator in the SDI device. To retain compatibility with the current board files, the old method of getting the regulator is kept. The old method can be removed when the board files have been changed to pass the regulator to SDI.
