drm/tinydrm: Fix fbdev pixel format

2019-04-11T14:16:06+00:00

Due to copy/paste error, the fbdev format was changed to 32bpp = XRGB8888
which is an emulated format for the RGB565 drivers. Revert to to using the
fallback which is dev->mode_config.preferred_depth for the drivers that
set it or 32bpp for those that don't (repaper, st7586).

drm: move tinydrm format conversion helpers to new drm_format_helper.c

Also rename them from tinydrm_* to drm_fb_*

drm/tinydrm: Use drm_dev_enter/exit()

2019-03-04T14:32:21+00:00

This protects device resources from use after device removal.

There are 3 ways for driver-device unbinding to happen:
- The driver module is unloaded causing the driver to be unregistered.
  This can't happen as long as there are open file handles because a
  reference is taken on the module.
- The device is removed (Device Tree overlay unloading).
  This can happen at any time.
- The driver sysfs unbind file can be used to unbind the driver from the
  device. This can happen any time.

v2: Since drm_atomic_helper_shutdown() has to be called after
    drm_dev_unplug() we don't want do block ->disable after unplug.

drm/tinydrm/repaper: Drop using tinydrm_device

2019-03-04T14:30:16+00:00

Use devm_drm_dev_init() and drop using tinydrm_device.

v2: devm_drm_dev_register() was dropped so add a driver release callback.

drm/tinydrm: Remove tinydrm_shutdown()

2019-02-21T11:21:44+00:00

It's just a wrapper around drm_atomic_helper_shutdown() now.
Also store drm_device in the drvdata field, since that's what's used.

drm/tinydrm: tinydrm_display_pipe_init() don't use tinydrm_device

2019-02-21T11:20:54+00:00

Rework function signature so tinydrm_device can be avoided.

Move definition to tinydrm-helpers.h so tinydrm.h can be deleted in a
later patch.

drm/tinydrm: Use damage helper for dirtyfb

2019-01-17T09:57:15+00:00

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

drm/tinydrm: Use struct drm_rect

2019-01-17T09:57:03+00:00

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

2019-01-09T21:48:56+00:00

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.
