drm/aperture: Remove primary argument

2023-04-16T12:17:41+00:00

Only really pci devices have a business setting this - it's for
figuring out whether the legacy vga stuff should be nuked too. And
with the preceding two patches those are all using the pci version of
this.

Which means for all other callers primary == false and we can remove
it now.

v2:
- Reorder to avoid compile fail (Thomas)
- Include gma500, which retained it's called to the non-pci version.

v4:
- fix Daniel's S-o-b address

v5:
- add back an S-o-b tag with Daniel's Intel address

drm/arm/hdlcd: Use devm_platform_ioremap_resource()

2023-03-17T14:57:17+00:00

According to commit 7945f929f1a7 ("drivers: provide
devm_platform_ioremap_resource()"), convert platform_get_resource(),
devm_ioremap_resource() to a single call to Use
devm_platform_ioremap_resource(), as this is exactly what this function
does.

Since 'struct platform_device *pdev = to_platform_device(drm->dev)',
'drm->dev' is equivalent to 'pdev->deva'.

arm/malidp: Use GEM DMA fbdev emulation

2023-03-14T16:07:47+00:00

Use the fbdev emulation that is optimized for DMA helpers. Avoids

drm/arm/malidp: use sysfs_emit in show function callback

2023-02-03T13:05:33+00:00

According to Documentation/filesystems/sysfs.rst, the show() callback
function of kobject attributes should strictly use sysfs_emit() instead
of sprintf() family functions.

drm/arm/komeda: Remove unnecessary include statements for drm_crtc_helper.h

2023-01-18T08:25:30+00:00

Several source files include drm_crtc_helper.h without needing it or
only to get its transitive include statements; leading to unnecessary
compile-time dependencies.

Drop drm_crtc_helper.h where possible.

drm: Include where needed

2023-01-13T12:18:35+00:00

Include  in source files that need it. Some of DRM's
source code gets OF header via drm_crtc_helper.h and ,
which can leed to unnecessary recompilation.

In drm_modes.c, add a comment on the reason for still including
. The header file is required to get KHZ2PICOS(). The
macro is part of the UAPI headers, so it cannot be moved to a less
prominent location.

v2:

drm/arm/hdlcd: use new debugfs device-centered functions

Replace the use of drm_debugfs_create_files() with the new
drm_debugfs_add_files() function, which center the debugfs files
management on the drm_device instead of drm_minor. Moreover, remove the
debugfs_init hook and add the debugfs files directly on hdlcd_drm_bind(),
before drm_dev_register().

drm/arm/malidp: remove calls to drm_mode_config_cleanup()

2022-11-16T10:33:45+00:00

drm_mode_config_init() simply calls drmm_mode_config_init(), hence
cleanup is automatically handled through registering
drm_mode_config_cleanup() with drmm_add_action_or_reset().

While at it, get rid of the deprecated drm_mode_config_init() and
replace it with drmm_mode_config_init() directly.
