2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
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.

2019-01-14drm: rcar-du: Remove inclusion of drmP.hLaurent Pinchart
The DRM kernel API used to be defined in a handful of headers, pulled in through drmP.h. It has since been split in multiple headers for the different DRM components, and drmP.h turned into a legacy header that just pulls in most of the DRM kernel API (and a large number of other miscellaneous kernel headers). In order to speed up compilation, replace inclusion of drmP.h with only the required headers. It turns out that the rcar-du-drm driver already includes most of the necessary headers, so the change is simple. While at it, remove unneeded inclusion of other headers, and unneeded forward declarations of structures.

2018-11-29drm/rcar-du: Use drm_fbdev_generic_setup()Noralf Trønnes
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

2018-09-25drm: rcar-du: Don't use TV sync mode when not supported by the hardwareLaurent Pinchart
The official way to stop the display is to clear the display enable (DEN) bit in the DSYSR register, but that operates at a group level and affects the two channels in the group. To disable channels selectively, the driver uses TV sync mode that stops display operation on the channel and turns output signals into inputs. While TV sync mode is available in all DU models currently supported, the D3 and E3 DUs don't support it. We will thus need to find an alternative way to turn channels off. In the meantime, condition the switch to TV sync mode to the availability of the feature, to avoid writing an invalid value to the DSYSR register. When the feature is unavailable the display output will turn blank as all planes are disabled when stopping the CRTC.

2018-05-05drm: rcar-du: Split CRTC handling to support hardware indexingKieran Bingham
The DU CRTC driver does not support distinguishing between a hardware index, and a software (CRTC) index in the event that a DU channel might not be populated by the hardware. Support this by adapting the rcar_du_device_info structure to store a bitmask of available channels rather than a count of CRTCs. The count can then be obtained by determining the hamming weight of the bitmask. This allows the rcar_du_crtc_create() function to distinguish between both index types, and non-populated DU channels will be skipped without leaving a gap in the software CRTC indexes.

2017-02-09drm: rcar-du: use vblank hooks in struct drm_crtc_funcsShawn Guo
The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead.

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.

2016-11-15drm: rcar-du: Simplify and fix probe error handlingLaurent Pinchart
It isn't safe to call drm_dev_unregister() without first initializing mode setting with drm_mode_config_init(). This leads to a crash if either IO memory can't be remapped or vblank initialization fails. Fix this by reordering the initialization sequence. Move vblank initialization after the drm_mode_config_init() call, and move IO remapping before drm_dev_alloc() to avoid the need to perform clean up in case of failure. While at it remove the explicit drm_vblank_cleanup() call from rcar_du_remove() as the drm_dev_unregister() function already cleans up vblank.

2016-11-14drm: rcar-du: Remove test for impossible error conditionLaurent Pinchart
The driver has lost platform data support a long time ago. R-Car DU devices can only be instantiated through DT now, making it impossible to have a NULL DT node pointer. Remove the error check.

2016-06-21drm/rcar-du: Remove redundant calls to drm_connector_register_all()Chris Wilson
Up to now, the recommendation was for drivers to call drm_dev_register() followed by drm_connector_register_all(). Now that drm_connector_register() is safe against multiple invocations, we can move drm_connector_register_all() to drm_dev_register() and not suffer from any backwards compatibility issues with drivers not following the more rigorous init ordering.
