From 3ade5bc4dc24edf5e1f13f3c43a9e8b7f8c2d853 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 18 Jan 2016 19:52:25 -0700 Subject: [PATCH] dm: video: sandbox: Convert sandbox to use driver model for video Now that driver model support is available, convert sandbox over to use it. We can remove a few of the special hooks that sandbox currently has.
