drm/docs: Add todo entry for drm_fb_helper_fbdev_setup()

drm/doc: Move legacy kms helpers to the very end

2017-12-15T10:26:54+00:00

We don't want people to accidentally stumble over there.

Also rename the plane helpers to legacy plane helpers. After Ville's
patch to make the clipping helper atomic and move it to
drm_atomic_helper.c there's nothing left in there that should be
useful for modern drivers.

v2: Laurent had a few questions around how state is added to
drm_atomic_state, tried to clarify that. And spotted another sentence
where the docs suggested subclassing.

v3: Small polish (Alex).

drm/atomic: document how to handle driver private objects

2017-12-15T10:26:54+00:00

DK put some nice docs into the commit introducing driver private
state, but in the git history alone it'll be lost.

Also, since Ville remove the void* usage it's a good opportunity to
give the driver private stuff some tlc on the doc front.

Finally try to explain why the "let's just subclass drm_atomic_state"
approach wasn't the greatest, and annotate all those functions as
deprecated in favour of more standardized driver private states. Also
note where we could/should extend driver private states going forward
(atm neither locking nor synchronization is handled in core/helpers,
which isn't really all that great).

v2: Spelling and phrasing improvements (Alex, DK).

docs: fix, intel_guc_loader.c has been moved to intel_guc_fw.c

2017-12-12T15:24:05+00:00

With commit d9e2e0143c the 'GuC-specific firmware loader' doc
section was removed from intel_guc_loader.c without a
replacement.  So lets remove it from the Kernel-doc::

  .. kernel-doc:: drivers/gpu/drm/i915/intel_guc_loader.c
     :doc: GuC-specific firmware loader

With commit e8668bbcb0 intel_guc_loader.c was renamed to to
intel_guc_fw.c and to name just one, intel_guc_init_hw() was
renamed to intel_guc_fw_upload(). Since we get errors in the
Sphinx build like:

- Error: Cannot open file ./drivers/gpu/drm/i915/intel_guc_loader.c

Change the kernel-doc directive from intel_guc_loader.c to
intel_guc_fw.c

drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini()

2017-12-10T14:37:07+00:00

Use drm_fb_cma_fbdev_init_with_funcs() 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.
Remove todo entry.

drm: Add panel orientation quirks, v6.

2017-12-04T22:03:21+00:00

Some x86 clamshell design devices use portrait tablet screens and a display
engine which cannot rotate in hardware, so the firmware just leaves things
as is and we cannot figure out that the display is oriented non upright
from the hardware.

So at least on x86, we need a quirk table for this. This commit adds a DMI
based quirk table which is initially populated with 5 such devices: Asus
T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17.

This quirk table will be used by the drm code to let userspace know that
the display is not mounted upright inside the devices case through a new
panel orientation drm-connector property, as well as to tell fbcon to
rotate the console so that it shows the right way up.

Changes in v5:
-Add a kernel-doc comment documenting drm_get_panel_orientation_quirk()
-Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop,
 keeping only the (identical) sys_vendor and product_name matches.
 This is necessary because an older version of the bios has
 board_vendor set to VOIS instead of VIOS

Changes in v6:
-Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst

Merge arlied/drm-next into drm-misc-next

2017-12-04T18:04:45+00:00

We need to pull 66660d4cf21b (drm: add connector info/property for
non-desktop displays [v2]) into drm-misc-next to continue the development
of the display rotation series.

Effectively this also pulls 4.15-r2 into drm-misc-next.
