drm-next This adds very rudimentary TCON (timing controller for raw LCD displays) support to enable the bypass mode in order to use the DCU controller on Freescale/NXP Vybrid SoC's. Additionally the register clock and pixel clock has been separated, but are currently still enabled and disabled pairwise. Other than that, fixes and cleanups accross the driver. * 'for-next' of http://git.agner.ch/git/linux-drm-fsl-dcu: drm/fsl-dcu: increment version and date drm/fsl-dcu: implement lastclose callback drm/fsl-dcu: disable output polling on driver unload drm/fsl-dcu: deallocate fbdev CMA on unload drm/fsl-dcu: use variable name dev for struct drm_device drm/fsl-dcu: handle missing panel gracefully drm/fsl-dcu: detach panel on destroy drm/layerscape: reduce excessive stack usage drm/fsl-dcu: add TCON driver drm/fsl-dcu: use common clock framework for pixel clock divider drm/fsl-dcu: add extra clock for pixel clock drm/fsl-dcu: disable clock on initialization failure and remove

https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into drm-next Allwinner DRM driver for 4.7 This pull request introduces the sun4i driver, meant to be used on the older Allwinner SoCs (A10, A13, A20, A23, A31 and A33). It currently supports only the A13, which has one of the simplest video pipeline. Support for other video components and SoCs will be added eventually. It supports only a RGB or composite output. It doesn't do HDMI, VGA, LVDS or power management yet, but that will come in time as well. * tag 'sun4i-drm-for-4.7' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux: MAINTAINERS: Add a maintainer for the Allwinner DRM driver drm: sun4i: tv: Add NTSC output standard drm: sun4i: tv: Add PAL output standard drm: sun4i: Add composite output drm: sun4i: Add RGB output drm: Add Allwinner A10 Display Engine support drm: sun4i: Add DT bindings documentation drm: fb: Add seq_file definition

2016-04-27drm: Switch blobs to the new generic modeset obj refcountingDaniel Vetter2-120/+45
Need to move the free function around a bit, but otherwise mostly just removing code. Specifically we can nuke all the _locked variants since the weak idr reference is now protected by the idr_mutex, which we never hold anywhere expect in the lookup/reg/unreg functions. And those never call anything else. Another benefit of this is that this patch switches the weak reference logic from kref_put_mutex to kref_get_unless_zero. And the later is in general more flexible wrt accomodating multiple weak references protected by different locks, which might or might not come handy eventually. But one consequence of that switch is that we need to acquire the blob_lock from the free function for the list_del calls. That's a bit tricky to pull off, but works well if we pick the exact same scheme as is already used for framebuffers. Most important changes: - filp list is maintainer by create/destroy_blob ioctls directly (already the case, so we can just remove the redundant list_del from the free function). - filp close handler walks the filp-private list lockless - works because we know no one else can access it. I copied the same comment from the fb code over to explain this. - Otherwise we need to sufficiently restrict blob_lock critical sections to avoid all the unreference calls. Easy to do once the blob_lock only protects the list, and no longer the weak reference.
