2016-09-22drm: Conslidate blending properties in drm_blend.[hc]Daniel Vetter
Imo zpos, rotatation, blending eq (once we have it) and all that should be in drm_blend.c, since those are all about how exactly the pixels are rendered onto the CRTC's visible area. Also noticed that one exported function accidentally ended up in drm_crtc_internal.h, move it to the right place too.

2016-09-22drm/doc: Polish for drm_plane.[hc]Daniel Vetter
Big thing is untangling and carefully documenting the different uapi types of planes. I also sprinkled a few more cross references around to make this easier to discover. As usual, remove the kerneldoc for internal functions which are not exported. Aside: We should probably go OCD on all the ioctl handlers and consistenly give them an _ioctl postfix.

2016-09-22drm: Extract drm_plane.[hc]Daniel Vetter
Just pure code movement, cleanup and polish will happen in later patches. v2: Don't forget all the ioctl! To extract those cleanly I decided to put check_src_coords into drm_framebuffer.c (and give it a drm_framebuffer_ prefix), since that just checks framebuffer constraints. v3: rebase over PAGE_FLIP_TARGET.

2016-09-20dma-buf/sync_file: Increment refcount of fence when all are signaled.Rafael Antognolli
When we merge several fences, if all of them are signaled already, we still keep one of them. So instead of using add_fence(), which will not increase the refcount of signaled fences, we should explicitly call fence_get() for the fence we are keeping. This patch fixes a kernel panic that can be triggered by creating a fence that is expired (or increasing the timeline until it expires), then creating a merged fence out of it, and deleting the merged fence. This will make the original expired fence's refcount go to zero.

2016-09-19drm: cleanup drm_core_{init,exit}()David Herrmann
Various cleanups to the DRM core initialization and exit handlers: - Register chrdev last: Once register_chrdev() returns, open() will succeed on the given chrdevs. This is usually not an issue, as no chardevs are registered, yet. However, nodes can be created by user-space via mknod(2), even though such major/minor combinations are unknown to the kernel. Avoid calling into drm_stub_open() in those cases. Again, drm_stub_open() would just bail out as the inode is unknown, but it's really non-obvious if you hack on drm_stub_open(). - Unify error-paths into just one label. All the error-path helpers can be called even though the constructors were not called yet, or failed. Hence, just call all cleanups unconditionally. - Call into drm_global_release(). This is a no-op, but provides debugging helpers in case there're GLOBALS left on module unload. This function was unused until now. - Use DRM_ERROR() instead of printk(), and also print the error-code on failure (even if it is static!). - Don't throw away error-codes of register_chrdev()! - Don't hardcode -1 as errno. This is just plain wrong. - Order exit-handlers in the exact reverse order of initialization (except if the order actually matters for syncing-reasons, which is not the case here, though). v2: - Call drm_core_exit() directly from the init-error-handler. Requires to drop __exit annotation, though.

2016-09-19drm: drop obsolete drm_core.hDavid Herrmann
The drm_core.h header contains a set of constants meant to be used throughout DRM. However, as it turns out, they're each used just once and don't bring any benefit. They're also grossly mis-named and lack name-spacing. This patch inlines them, or moves them into drm_internal.h as appropriate: - CORE_AUTHOR and CORE_DESC are inlined into corresponding MODULE_*() macros. It's just confusing having to follow 2 pointers when trying to find the definition of these fields. Grep'ping for MODULE_AUTHOR() should reveal the full information, if there's no strong reason not to. - CORE_NAME, CORE_DATE, CORE_MAJOR, CORE_MINOR, and CORE_PATCHLEVEL are inlined into the sysfs 'version' attribute. They're stripped everywhere else (which is just some printk() statements). CORE_NAME just doesn't make *any* sense, as we hard-code it in many places, anyway. The other constants are outdated and just serve binary-compatibility purposes. Hence, inline them in 'version' sysfs attribute (we might even try dropping it..). - DRM_IF_MAJOR and DRM_IF_MINOR are moved into drm_internal.h as they're only used by the global ioctl handlers. Furthermore, versioning interfaces breaks backports and as such is deprecated, anyway. We just keep them for historic reasons. I doubt anyone will ever modify them again.

2016-09-19drm: remove redundant drm_file->uidDavid Herrmann
Each DRM file-context caches the EUID of the process that opened the file. It is used exclusively for debugging purposes in /proc/dri/ and friends. Note, however, that we can already fetch the EUID from priv->pid->task->creds. The pointer-chasing will not hurt us, since it is only about debugging, anyway. Since we already are in an rcu-read-side, we can use __task_cred() rather than task_cred_xxx().

2016-09-15drm: Only use compat ioctl for addfb2 on X86/IA64Kristian H. Kristensen
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw.

2016-09-12drm: Move property validation to a helper, v2.Maarten Lankhorst
Property lifetimes are equal to the device lifetime, so the separate drm_property_find is not needed. The pointer can be retrieved from the properties member, which saves us some locking and a extra lookup. The lifetime for properties is until the device is destroyed, which happens late in the device unload path. kms_atomic is also testing for invalid properties which returns -ENOENT, to be consistent return -ENOENT for valid properties that don't appear on the object property list. Changes since v1: - Return -ENOENT for invalid properties to make kms_atomic pass. - Change commit message slightly to take this into account.

2016-09-08drm/sun4i: Add a DRC driverMaxime Ripard
The A33 pipeline also has a component called DRC. Even though its exact features and programming model is not known (or documented), it needs to be clocked for the pipeline to carry the video signal all the way. Add a minimal driver for it that just claim the needed resources for the pipeline to operate properly.

2016-09-08drm/sun4i: backend: Handle the SATMaxime Ripard

2016-09-07drm/i2c: tda998x: Register ASoC hdmi-codec and add audio DT bindingJyri Sarha
Register ASoC HDMI codec for audio functionality and adds device tree binding for audio configuration. With the registered HDMI codec the tda998x node can be used like a regular codec node in ASoC card configurations. HDMI audio info-frame and audio stream header is generated by the ASoC HDMI codec. The codec also applies constraints for available sample-rates based on Edid Like Data from the display. The device tree binding document has been updated [1]. Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x: Add support of a DT graph of ports"-patch [2]. There may still be some identical lines left from the original patch and some of the ideas have come from there.
