This patch fixes wrong pixel format setting. A pixel format is decided according to bpp and depth, or user-requested format but fimd driver considered only bpp value to decide a proper pixel format.

The exynos4 platform is only dt-based since 3.10, we should convert driver data and ids to dt-based parsing methods. The rotator driver has a limit table to get size limit of input picture. Each SoCs has slightly different limit value compared with any others. For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have 8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size for its X/Y axis. Thus, we should keep different tables for each of them. This patch also includes desciptions of each nodes for the rotator and specifies a example how to bind it.

This is the 2nd attempt, I've always been a bit dissatisified with the tricky nature of the first one: http://lists.freedesktop.org/archives/dri-devel/2012-July/025451.html The issue is that the flink ioctl can race with calling gem_close on the last gem handle. In that case we'll end up with a zero handle count, but an flink name (and it's corresponding reference). Which results in a neat space leak. In my first attempt I've solved this by rechecking the handle count. But fundamentally the issue is that ->handle_count isn't your usual refcount - it can be resurrected from 0 among other things. For those special beasts atomic_t often suggest way more ordering that it actually guarantees. To prevent being tricked by those hairy semantics take the easy way out and simply protect the handle with the existing dev->object_name_lock. With that change implemented it's dead easy to fix the flink vs. gem close reace: When we try to create the name we simply have to check whether there's still officially a gem handle around and if not refuse to create the flink name. Since the handle count decrement and flink name destruction is now also protected by that lock the reace is gone and we can't ever leak the flink reference again. Outside of the drm core only the exynos driver looks at the handle count, and tbh I have no idea why (it's just for debug dmesg output luckily). I've considered inlining the drm_gem_object_handle_free, but I plan to add more name-like things (like the exported dma_buf) to this scheme, so it's clearer to leave the handle freeing in its own function. This is exercised by the new gem_flink_race i-g-t testcase, which on my snb leaks gem objects at a rate of roughly 1k objects/s. v2: Fix up the error path handling in handle_create and make it more robust by simply calling object_handle_unreference. v3: Fix up the handle_unreference logic bug - atomic_dec_and_test retursn 1 for 0. Oops. v4: Squash in inlining of drm_gem_object_handle_reference as suggested by Dave Airlie and add a note that we now have a testcase.

Note that this is slightly tricky since both drivers store their native objects in dma_buf->priv. But both also embed the base drm_gem_object at the first position, so the implicit cast is ok.

All the gem based kms drivers really want the same function to destroy a dumb framebuffer backing storage object. So give it to them and roll it out in all drivers. This still leaves the option open for kms drivers which don't use GEM for backing storage, but it does decently simplify matters for gem drivers.
