drm/armada: move armada_drm_mode_config_funcs to armada_drv.c

2018-07-30T10:52:34+00:00

Move the armada_drm_mode_config_funcs to armada_drv.c, since this now
has less to do with FBs than it does with general mode configuration.
In doing so, we need to make armada_fb_create() visible to armada_drv.c,
which reveals a function name clash with armada_fbdev.c.  Rename the
version in armada_fbdev.c.

drm/armada: Use drm_fb_helper_lastclose() and _poll_changed()

2017-12-08T12:03:52+00:00

This driver can use drm_fb_helper_lastclose() as its .lastclose callback.
It can also use drm_fb_helper_output_poll_changed() as its
.output_poll_changed callback.

drm/armada: Replace drm_gem_object_reference/unreference() with _get/put()

2017-10-16T19:01:51+00:00

This patch replace instances of drm_gem_object_reference/unreference with
*_get/put() suffixes, because get/put is shorter and consistent with the
kernel use of *_get/put() suffixes.
This was done with the following Coccinelle script:

@r1@
expression e;
@@

(
-drm_gem_object_reference(e);
+drm_gem_object_get(e);
|
-drm_gem_object_unreference(e);

drm/: Drop fbdev info flags

2017-07-26T11:22:40+00:00

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
  the entire panic handling code in our fbdev emulation. We might
  restore kms panic output, but not through the bazillion of legacy
  code layers called fbdev/fbcon, there's just no way to make that
  work safely.

- With the module check change FBINFO_DEFAULT is always 0, so can be
  removed too.

That removes another change to cargo-cult stuff in kms drivers, yay!

drm/fb-helper: Automatically clean up fb_info

2017-02-07T20:36:28+00:00

Noticed that everyone duplicates the same logic here and we could safe
a few lines per driver. Yay for lots of drivers to make such tiny
refactors worth-while!

v2: Forgot to git add everything :(

v3: Actually remove release_fbi (Sean, Emil, Chris) ...

drm: Rely on mode_config data for fb_helper initialization

2017-02-02T18:12:00+00:00

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure.  I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.

I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates.  The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.
