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.

drm/tinydrm: Use damage helper for dirtyfb

2019-01-17T09:57:15Z

This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty handler. All flushing will now happen in the pipe functions. Also enable the damage plane property for all except repaper which can only do full updates. ili9225: This change made ili9225_init() equal to mipi_dbi_init() so use it. v3: Include vblank header (Sam) ili9225 and st7586 can't use mipi_dbi_enable_flush() (David) v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL (kbuild test robot) Cc: David Lechner Cc: Eric Anholt Signed-off-by: Noralf Trønnes Acked-by: Daniel Vetter Reviewed-by: Sam Ravnborg Tested-by: David Lechner Reviewed-by: David Lechner Link: https://patchwork.freedesktop.org/patch/msgid/20190115043643.2364-5-noralf@tronnes.org

drm/tinydrm: Use struct drm_rect

2019-01-17T09:57:03Z

This prepares for the switch to drm_atomic_helper_dirtyfb() in the next patch. The damage helper returns a drm_rect so switch to that everywhere including using a pointer in the dirty functions. This is a non-functional change except for the debug print which looks a bit different.

drm/tinydrm: do not reply on drmP.h from drm_gem_cma_helper.h

2019-01-09T21:48:56Z

drmP.h was the only header file in the past and a lot of files rely on that drmP.h defines everything. The goal is to one day to delete drmP.h and as a step towards this it will no longer be included in the headers files in include/drm/ To prepare tinydrm/ for this add dependencies that othwewise was pulled in by drmP.h from drm_gem_cma_helper.h To avoid that tinydrm.h became "include everything", push include files to the individual drivers.

drm/tinydrm: Use DRM_GEM_CMA_VMAP_DRIVER_OPS

2018-11-20T13:58:19Z

The CMA helper now has the functionality to ensure a virtual address on imported buffer so use that. While touching all tinydrm drivers, remove the unnecessary inclusion of drm_fb_helper.h in some drivers.

drm: Add an hx8367d tinydrm driver.

2018-10-30T23:23:38Z

I want to sort out support for tinydrm in vc4, so I needed to get a tinydrm-appropriate panel working and this is what I had on hand. This is derived from a combination of ili9341.c from tinydrm and fb_hx8357d.c from staging's fbtft. v2: Write my own register defs from the spec to not need the header from fbtft. Fix spi device string to enable module autoloading.

Without this, the xserver relies on what the 3D driver exposes and assumes that the display can handle it, and then the DRM driver happily tries to scan out a tiled format.
