2012-03-30video: tegra: host: do not assume 3d channel opened by user spaceMayuresh Kulkarni
- if user space does not open 3d channel, 3d scaling algorithm is not initialized. so return safely when 3d scaling is disabled - also do not call nvhost_module_suspend() explicitly for host1x client modules. nvhost_channel_suspend() takes care to suspend the module if ref count = 0 - call nvhost_module_suspend() only for host1x device as it does not use actual hardware channel Bug 953451 Change-Id: Iba2b771b71d9b41c8ed978112566181872c56259 Signed-off-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> Reviewed-on: http://git-master/r/92506 Reviewed-by: Automatic_Commit_Validation_User Tested-by: Peer Chen <pchen@nvidia.com> Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: Emily Jiang <ejiang@nvidia.com>

This change adds a flag to flip windows in cursor mode. Cursor mode will cause flips to be skipped over if there are newer flip requests waiting in the workqueue.

2012-03-21video: tegra: dc: disable disp.emc clock when 0 new rate is requestedNitin Kumbhar
Not disabling emc clock when it's being set to zero results in incorrect reference count when a call is made to clear bandwidth. This happens when two worker threads try to handle dc emc rate. A deep-sleep/wake-up cycle easily shows this scenario. With this fix, disp.emc's ref count is properly managed even after multiple deep-sleep/wake-up cycles.
