2012-04-26video: tegra: host: Reset 3D after power onTerje Bergstrom
Sometimes 3D unit comes up with incorrect scissor configuration. Earlier patch added the scissor registers to the context save list, but that did not solve the problem. Remove the extra registers, and reset 3D after powering it up.

2012-03-15video: tegra: host: Refactor context handling logicTerje Bergstrom
Currently nvhost hard codes usage of context handler and sync point id. Split the context handler and context structures into generic and host1x specific parts, and move the allocation to happen via a function pointer in nvhost_device. Also updates gr3d and mpe to use sync point id and waitbase from nvhost_device.

2012-03-15video: tegra: nvmap: Fix issue in handle_page_allocKrishna Reddy
Fix race condition in handle_page_alloc. Page allocations should not try allocate from pool, once it fails for a request. If it tries and allocation passes during subsequent attempts, the page_index is not valid for CPA and cache won't be flushed for all the necessary pages.

2012-03-15video: tegra: hdmi: validate clocks per frame of HDMI modeYoungjin Kim
There are HDMI modes which have different margin/sync values although resolution and pixel clock are the same. One example is 1080p/24Hz and 1080p/30Hz case. Those modes are not distinguished when we check if given two modes are equal. So clocks per frame also should be validated to decide sameness of the modes.

2012-03-15video: tegra: dc: Add rated refresh rate for one-shot mode.Kevin Huang
We add this variable for two purposes. First, it would remind developer to make sure actual refresh rate is larger than rated refresh rate. Second, gralloc would read rated refresh rate for one-shot mode since actual refresh rates of most devices are expected running at rated refresh rate.
