2015-06-24mmc: tegra: reverify tuning best tapBibek Basu
tuning best_tap_value at times throws wrong value leading to data crc error. To make the SW robust, reverify tuning best_tap_value with previously calculated and then only proceed.

2015-06-19media: tegra_camera: add start streaming callBryan Wu
Queueing buffer might happen before starting streaming. So any queueing buffer operation before starting streaming shouldn't trigger real capture but just queue the buffer. After starting streaming, it will wake up kernel workqueue to start real capture.

2015-06-19media: tegra_camera: optimize single shot modeBryan Wu
Current single shot mode, pixel parser is disabled after capture one frame and software waits for memory write ack done syncpoint, which only gives us half the frame rate. Optimized single shot mode: - during capture setup, set single shot mode - for each frame, wait for FRAME_START syncpoint - arm single shot bit to start capture - for the last frame, wait for MWA_DONE syncpoint to make sure capture finished. With optimized single shot mode, frame rate is about 4208x3120 @ 24fps for IMX135 and 1920x1080 @ 30fps for AR0261.

The HDMI state machine registers an IRQ handler before all the resources it needs are available. Ideally the IRQ handler should be registered later, however it would mean a quite large change. Instead we just add some check to avoid running the state machine as long as the framebuffer hasn't been registered. While at it also prevent scheduling the state machine if it hasn't been initialized yet.

lockdep complains about the alloc_page call under the pool lock in nvmap_page_pool_init because the pool lock is also taken during reclaim in nvmap_page_pool_shrink. Rewrite nvmap_page_pool_init to perform the allocation in PENDING_PAGES_SIZE chunks outside the lock. Also move the global pending_pages to a static copy in nvmap_pp_do_background_zero_pages and a kcalloc'd array during init to avoid conflicts when two threads try to use the same array.

2015-05-12nvmap: page pools: replace background allocator with background zeroerColin Cross
The background allocator rapidly becomes useless once the system has filled memory with cached pages. It refuses to allocate when free memory < 128MB (which it always is, the kernel is aiming to keep very little free), and freed pages are not returned to the page pool when zero_memory=1. Remove the background allocator completely, and instead return freed memory to the page pool in a separate list to be zeroed in the background. This results in a self-balancing pool of memory available to graphics, and reduces presure on the kernel's page allocator. If the pool grows too big it will get reduced by the shrinker. If it gets too small, the next allocation will fall back to the page allocator, and then later return those pages to the pool. Before this change incremental page pool hit rate reported by /d/nvmap/pagepool/page_pool_hits vs. /d/nvmap/pagepool/page_pool_misses goes to 0% after boot. After this change it is near 100% for small app launches and 75% for larger app launches.

Use a waitqueue instead.
