drm/irq: Don't check for DRIVER_HAVE_IRQ in drm_irq_(un)install

2019-01-29T14:45:06Z

If a non-legacy driver calls these it's valid to assume there is interrupt support. The flag is really only needed for legacy drivers, which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL legacy IOCTL. Also remove all the flag usage from non-legacy drivers. v2: Review from Emil: - improve commit message - I forgot hibmc, fix that Cc: linux-arm-kernel@lists.infradead.org Cc: intel-gfx@lists.freedesktop.org Cc: linux-amlogic@lists.infradead.org Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Cc: virtualization@lists.linux-foundation.org Cc: spice-devel@lists.freedesktop.org Cc: amd-gfx@lists.freedesktop.org Cc: linux-renesas-soc@vger.kernel.org Reviewed-by: Emil Velikov Reviewed-by: Sam Ravnborg Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190129104248.26607-1-daniel.vetter@ffwll.ch

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42Z

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.

Register cpufreq notifier after we have initialized the crtc and unregister it before we remove the ctrc. Receiving a cpufreq notify without crtc causes a crash. Reported-by: Peter Ujfalusi Signed-off-by: Jyri Sarha

drm/tilcdc: Use drm_fbdev_generic_setup()

2018-11-01T14:25:41Z

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/tilcdc: Defer probe if there are no connectors

2018-07-05T11:06:22Z

During probe there may not be any connectors yet if e.g. the panel failed or hasn't been probed yet. I hitting this in practice the panels probing was being delayed due to using a gpio backlight. Fix this by returning -EPROBE_DEFER so the probing will be retried. Signed-off-by: Sjoerd Simons Signed-off-by: Jyri Sarha

drm/tilcdc: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:42Z

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly.
