2017-06-26drm/hibmc: Drop drm_vblank_cleanupDaniel Vetter
So this seems to be the first driver that does it the right way round, so fix it up by calling drm_atomic_helper_shutdown instead. We need to do that before the last kms user is gone (fbdev emulation), but before we start shutting down hw stuff like interrupts.

2017-06-06drm: kirin: Fix drm_of_find_panel_or_bridge conversionJohn Stultz
This fixes a regression introduced by ebc944613567 ("drm: convert drivers to use drm_of_find_panel_or_bridge") that was recently merged, causing HDMI output to not work. For the kirin driver, the port value should be 1 instead of 0, so this oneline patch fixes it and gets graphics working again.

2017-04-06drm: convert drivers to use drm_of_find_panel_or_bridgeRob Herring
Similar to the previous commit, convert drivers open coding OF graph parsing to use drm_of_find_panel_or_bridge instead. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages. Plus the kernel is not a DT validator.

2017-04-06drm: convert drivers to use of_graph_get_remote_nodeRob Herring
Convert drivers to use the new of_graph_get_remote_node() helper instead of parsing the endpoint node and then getting the remote device node. Now drivers can just specify the device node and which port/endpoint and get back the connected remote device node. The details of the graph binding are nicely abstracted into the core OF graph code. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages.

2017-03-14drm: Create DEFINE_DRM_GEM_CMA_FOPS and roll it out to driversDaniel Vetter
Less code ftw. This converts all drivers except the tinydrm helper module. That one needs more work, since it gets the THIS_MODULE reference from tinydrm.ko instead of the actual driver module like it should. Probably needs a similar trick like I used here with generating the entire struct with a macro.

2017-02-07drm: remove drm_vblank_no_hw_counter assignment from driver codeShawn Guo
Core code already makes drm_driver.get_vblank_counter hook optional by letting drm_vblank_no_hw_counter be the default implementation for the function hook. So the drm_vblank_no_hw_counter assignment in the driver code becomes redundant and can be removed now.

Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates.

2016-12-13drm/hisilicon: Don't set drm_device->platformdevDaniel Vetter
It's deprecated and only should be used by drivers which still use drm_platform_init, not by anyone else. And indeed it's entirely unused and can be nuked. This required a bit more fudging, but I guess kirin_dc_ops really wants to operate on the platform_device, not something else. Also bonus points for implementing abstraction, and then storing the vfunc in a global variable. v2: Don't break the build soooo badly :( Note that the cleanup function is a bit confused: ade_data was never set as drvdata, and calling drm_crtc_cleanup directly is a bug - this is called indirectly through drm_mode_config_cleanup, which calls into crtc->destroy, which already has the call to drm_crtc_cleanup. Which means we can just nuke it.

2016-12-01drm: Make the connector .detect() callback optionalLaurent Pinchart
Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.

2016-11-12drm: move allocation out of drm_get_format_name()Eric Engestrom
The function's behaviour was changed in 90844f00049e, without changing its signature, causing people to keep using it the old way without realising they were now leaking memory. Rob Clark also noticed it was also allocating GFP_KERNEL memory in atomic contexts, breaking them. Instead of having to allocate GFP_ATOMIC memory and fixing the callers to make them cleanup the memory afterwards, let's change the function's signature by having the caller take care of the memory and passing it to the function. The new parameter is a single-field struct in order to enforce the size of its buffer and help callers to correctly manage their memory.

Since commit 4984979b9b90 ("drm/irq: simplify irq checks in drm_wait_vblank"), the drm driver feature flag DRIVER_HAVE_IRQ is only required for drivers that have an IRQ handler managed by the DRM core. Some drivers, armada, etnaviv, kirin and sti, set this flag without .irq_handler setup in drm_driver. These drivers manage IRQ handler by themselves and the flag DRIVER_HAVE_IRQ makes no sense there. Drop the flag for these drivers to avoid confusion.

2016-06-21drm: Lobotomize set_busid nonsense for !pci driversDaniel Vetter
We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.
