video: tegra: host: register nvhost master device in board-xxx-panel.c
- the suspend order of devices is governed by the order in which devices are registered - this commit ensures that nvhost master is registered before any of the graphics devices - previously this was done in rootfs_init call which is later than arch_init calls of board-xxx-panel.c - this caused tegra-dc device to be registered *before* nvhost master device. as a result it was suspended *later* than nvhost master device. this is a clear violation of dependency rule for nvhost. this caused suspend-resume to fail for L4T - this worked on android as it has CONFIG early suspend enabled while it failed for L4T which doesn't have CONFIG early suspend enabled Bug 947617 Change-Id: I6cd405f3ba23d004e7659140019f5130e6c25159 Signed-off-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> Reviewed-on: http://git-master/r/87756 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
