| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add driver for the TCON (timing controller) module. The TCON module is a separate module attached after the DCU (display controller unit). Each DCU instance has its own, directly connected TCON instance. The DCU's RGB and timing signals are passing through the TCON module. TCON can provide timing signals for raw TFT panels or operate in a bypass mode which leaves all signals unaltered. The driver currently only supports the bypass mode.

| | | | | | | | | | | | | | | | | | | | | | Use the common clock framework to calculate the pixel clock dividier. The previous implementation rounded down the calculated factor. Thanks to the CLK_DIVIDER_ROUND_CLOSEST flag using the common clock framework divider implementation improves the pixel clock accuracy in some cases.

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.

* | drm: rcar-du: Clarify vsp dependencyArnd Bergmann2016-04-241-1/+1
|/ | | | | | | | | | | | | | | | | | The VSP1 compositor code in DRM links against the respective V4L driver, but the dependency is not expressed correctly in Kconfig, which leads to a build error when the DRM driver is built-in and the V4L driver is a module: drivers/gpu/built-in.o: In function `rcar_du_vsp_plane_atomic_update': rcar-du/rcar_du_vsp.c:183: undefined reference to `vsp1_du_atomic_update' This patch avoids the problem by ensuring that the DRM VSP code can only be enabled if the V4L driver is linked into the kernel, or both are loadable modules.

* drm/modes: reduce fb_lock to just protecting listsDave Airlie2016-04-221-8/+1
| | | | | | | | | | | | | This reduces the fb_lock to just protecting the num_fb/fb_list. "Previously fb refcounting, and especially the weak reference (kref_get_unless_zero) used in fb lookups have been protected by fb_lock. But with the refactoring to share refcounting in the drm_mode_object base class that switched to being protected by idr_mutex, which means fb_lock critical sections can be reduced."
