* drm: Stop including drm_bridge.h from drm_crtc.hBoris Brezillon2019-08-281-0/+1
| | | | | | | | | | | | | | We are about to add a drm_bridge_state that inherits from drm_private_state which is defined in drm_atomic.h. Problem is, drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h, leading to "drm_private_state has incomplete type" error. Let's force all users of the drm_bridge API to explicitly include drm_bridge.h.

* drm/imx: fix opencoded use of drm_panel_*Sam Ravnborg2019-08-101-7/+4
| | | | | | | | | | | | | | | | | | | | | | | Use the drm_panel_get_modes() function to get the modes. This patch leave one test for the function pointer: panel->funcs->get_modes This is used to check if the panel may have any modes. There is no direct replacement. We may be able to just check that drm_panel_get_modes() return > 0, but as this is not the same functionality it is left for later.

* drm: Split out drm_probe_helper.hDaniel Vetter2019-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

* drm: Do not set connector->encoder in driversThierry Reding2016-01-131-2/+0
| | | | | | | | | | | | | | | | | | | | | | An encoder is associated with a connector by the DRM core as a result of setting up a configuration. Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.

We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

* drm: imx: Move imx-drm driver out of stagingPhilipp Zabel2014-11-261-0/+296
The imx-drm driver was put into staging mostly for the following reasons, all of which have been addressed or superseded: - convert the irq driver to use linear irq domains - work out the device tree bindings, this lead to the common of_graph bindings being used - factor out common helper functions, this mostly resulted in the component framework and drm of_graph helpers. Before adding new fixes, and certainly before adding new features, move it into its proper place below drivers/gpu/drm.
