Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of  by the more specific
 where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Merge v7.1-rc5 into drm-next

2026-05-28T07:58:36+00:00

Boris Brezillion needs the gem lru fixes 379e8f1ca5e9 ("drm/gem: Make
the GEM LRU lock part of drm_device") backmerged for drm-misc-next.
That also means we need to sort out the rename conflict in panthor with
the fixup patch from Boris from drm-tip.

drm/mediatek: dsi: Add compatible for mt8167-dsi

2026-05-18T13:44:33+00:00

The mt8167 DSI controller is fully compatible with the one found in
mt2701. Unfortunately the device tree has a dedicated compatible for
mt8167 since 2022 and it cannot be changed with a fallback nor removed at
this point. The only way to get the device to work is to add the
compatible to the driver.

drm/mediatek: Convert legacy DRM logging to drm_* helpers in mtk_dsi.c

2026-05-18T13:35:40+00:00

Replace DRM_INFO(), DRM_WARN() and DRM_ERROR() calls in
drivers/gpu/drm/mediatek/mtk_dsi.c with the corresponding
drm_info(), drm_warn() and drm_err() helpers.

The drm_*() logging helpers take a struct drm_device * argument,
allowing the DRM core to prefix log messages with the correct device
name and instance. This is required to correctly distinguish log
messages on systems with multiple GPUs.

This change aligns the radeon driver with the DRM TODO item:
"Convert logging to drm_* functions with drm_device parameter".

drm/mediatek: mtk_dpi: Open-code drm_simple_encoder_init()

2026-05-13T14:55:46+00:00

The helper drm_simple_encoder_init() is a trivial wrapper around
drm_encoder_init() that only provides a static drm_encoder_funcs with
.destroy set to drm_encoder_cleanup(). Open-code the initialization
with a driver-specific instance of drm_encoder_funcs and remove the
dependency on drm_simple_kms_helper.
