Pull media updates from Mauro Carvalho Chehab: "This series contains: - Exynos s5p-mfc driver got support for VP8 encoder - Some SoC drivers gained support for asynchronous registration (needed for DT) - The RC subsystem gained support for RC activity LED; - New drivers added: a video decoder(adv7842), a video encoder (adv7511), a new GSPCA driver (stk1135) and support for Renesas R-Car (vsp1) - the first SDR kernel driver: mirics msi3101. Due to some troubles with the driver, and because the API is still under discussion, it will be merged at staging for 3.12. Need to rework on it - usual new boards additions, fixes, cleanups and driver improvements" * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (242 commits) [media] cx88: Fix regression: CX88_AUDIO_WM8775 can't be 0 [media] exynos4-is: Fix entity unregistration on error path [media] exynos-gsc: Register v4l2 device [media] exynos4-is: Fix fimc-lite bayer formats [media] em28xx: fix assignment of the eeprom data [media] hdpvr: fix iteration over uninitialized lists in hdpvr_probe() [media] usbtv: Throw corrupted frames away [media] usbtv: Fix deinterlacing [media] v4l2: added missing mutex.h include to v4l2-ctrls.h [media] DocBook: upgrade media_api DocBook version to 4.2 [media] ml86v7667: fix compile warning: 'ret' set but not used [media] s5p-g2d: Fix registration failure [media] media: coda: Fix DT driver data pointer for i.MX27 [media] s5p-mfc: Fix input/output format reporting [media] v4l: vsp1: Fix mutex double lock at streamon time [media] v4l: vsp1: Add support for RT clock [media] v4l: vsp1: Initialize media device bus_info field [media] davinci: vpif_capture: fix error return code in vpif_probe() [media] davinci: vpif_display: fix error return code in vpif_probe() [media] MAINTAINERS: add entries for adv7511 and adv7842 ...

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. Signed-off-by:

Pull Xen updates from Konrad Rzeszutek Wilk: "A couple of features and a ton of bug-fixes. There is also some maintership changes. Jeremy is enjoying the full-time work at the startup and as much as he would love to help - he can't find the time. I have a bunch of other things that I promised to work on - paravirt diet, get SWIOTLB working everywhere, etc, but haven't been able to find the time. As such both David Vrabel and Boris Ostrovsky have graciously volunteered to help with the maintership role. They will keep the lid on regressions, bug-fixes, etc. I will be in the background to help - but eventually there will be less of me doing the Xen GIT pulls and more of them.

Features: - Xen Trusted Platform Module (TPM) frontend driver - with the backend in MiniOS. - Scalability improvements in event channel. - Two extra Xen co-maintainers (David, Boris) and one going away (Jeremy) Bug-fixes: - Make the 1:1 mapping work during early bootup on selective regions. - Add scratch page to balloon driver to deal with unexpected code still holding on stale pages. - Allow NMIs on PV guests (64-bit only) - Remove unnecessary TLB flush in M2P code. - Fixes duplicate callbacks in Xen granttable code. - Fixes in PRIVCMD_MMAPBATCH ioctls to allow retries - Fix for events being lost due to rescheduling on different VCPUs. - More documentation" * tag 'stable/for-linus-3.12-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: (23 commits) hvc_xen: Remove unnecessary __GFP_ZERO from kzalloc drivers/xen-tpmfront: Fix compile issue with missing option. xen/balloon: don't set P2M entry for auto translated guest xen/evtchn: double free on error Xen: Fix retry calls into PRIVCMD_MMAPBATCH*. xen/pvhvm: Initialize xen panic handler for PVHVM guests xen/m2p: use GNTTABOP_unmap_and_replace to reinstate the original mapping xen: fix ARM build after 6efa20e4 MAINTAINERS: Remove Jeremy from the Xen subsystem. xen/events: document behaviour when scanning the start word for events x86/xen: during early setup, only 1:1 map the ISA region x86/xen: disable premption when enabling local irqs swiotlb-xen: replace dma_length with sg_dma_len() macro swiotlb: replace dma_length with sg_dma_len() macro xen/balloon: set a mapping for ballooned out pages xen/evtchn: improve scalability by using per-user locks xen/p2m: avoid unneccesary TLB flush in m2p_remove_override() MAINTAINERS: Add in two extra co-maintainers of the Xen tree.

Pull PTR_RET() removal patches from Rusty Russell: "PTR_RET() is a weird name, and led to some confusing usage. We ended up with PTR_ERR_OR_ZERO(), and replacing or fixing all the usages. This has been sitting in linux-next for a whole cycle" [ There are still some PTR_RET users scattered about, with some of them possibly being new, but most of them existing in Rusty's tree too.

Pull ext4 updates from Ted Ts'o: "New features for 3.12: - Added aggressive extent caching using the extent status tree. This can actually decrease memory usage in read-mostly workloads since the information is much more compactly stored in the extent status tree than if we had to keep the extent tree metadata blocks in the buffer cache. This also improves Asynchronous I/O since it is it makes much less likely that we need to do metadata I/O to lookup the extent tree information. - Improve the recovery after corrupted allocation bitmaps are found when running in errors=ignore mode. Also fixed some writeback vs truncate races when using a blocksize less than the page size" * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (25 commits) ext4: allow specifying external journal by pathname mount option ext4: mark group corrupt on group descriptor checksum ext4: mark block group as corrupt on inode bitmap error ext4: mark block group as corrupt on block bitmap error ext4: fix type declaration of ext4_validate_block_bitmap ext4: error out if verifying the block bitmap fails jbd2: Fix endian mixing problems in the checksumming code ext4: isolate ext4_extents.h file ext4: Fix misspellings using 'codespell' tool ext4: convert write_begin methods to stable_page_writes semantics ext4: fix use of potentially uninitialized variables in debugging code ext4: fix lost truncate due to race with writeback ext4: simplify truncation code in ext4_setattr() ext4: fix ext4_writepages() in presence of truncate ext4: move test whether extent to map can be extended to one place ext4: fix warning in ext4_da_update_reserve_space() quota: provide interface for readding allocated space into reserved space ext4: avoid reusing recently deleted inodes in no journal mode ext4: allocate delayed allocation blocks before rename ext4: start handle at least possible moment when renaming files ...
