drm/ipv3: add CONFIG_OF dependency for DRM_OF_DISPLAY_MODE_BRIDGE

2026-05-04T10:03:59+00:00

Without this, not all dependencies are met here.

  Depends on [n]: HAS_IOMEM [=y] && DRM [=y] && DRM_BRIDGE [=y] && OF [=n]
  Selected by [y]:

drm/bridge: Move legacy bridge driver out of imx directory for multi-platform use

2026-04-09T12:10:21+00:00

As suggested by Dmitry, the DRM legacy bridge driver can be pulled
out of imx/ subdir for multi-platform use. The driver is also renamed
to make it more generic and suitable for platforms other than i.MX.

drm/imx: parallel-display: add DRM_DISPLAY_HELPER for DRM_IMX_PARALLEL_DISPLAY

2026-03-13T15:26:32+00:00

When I build for an old imx53 platform I see the same as the test robot
saw before:

arm-buildroot-linux-gnueabihf-ld: drivers/gpu/drm/imx/ipuv3/parallel-display.o: in function `imx_pd_bind':
parallel-display.c:(.text+0xb8): undefined reference to `drm_bridge_connector_init'

Selecting DRM_DISPLAY_HELPER for DRM_IMX_PARALLEL_DISPLAY fixes the build.

drm/imx: parallel-display: add legacy bridge Kconfig dependency

2024-10-22T13:37:19+00:00

The driver now uses the legacy bridge helper code but can be configured
to get built without it:

ERROR: modpost: "devm_imx_drm_legacy_bridge" [drivers/gpu/drm/imx/ipuv3/parallel-display.ko] undefined!

Add the required dependency, same as in the ldb driver.

drm/imx/ipuv3: Run DRM default client setup

2024-09-26T06:28:02+00:00

Call drm_client_setup_with_color_mode() to run the kernel's default
client setup for DRM. Set fbdev_probe in struct drm_driver, so that
the client setup can start the common fbdev client.

v5:
- select DRM_CLIENT_SELECTION

When drm/bridge-connector was moved to DRM_DISPLAY_HELPER not all
users were updated. Add missing Kconfig selections.

drm/imx: ldb: switch to imx_legacy_bridge / drm_bridge_connector

2024-09-02T23:35:35+00:00

Use the imx_legacy bridge driver instead of handlign display modes via
the connector node.

All existing usecases already support attaching using
the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag, while the imx_legacy bridge
doesn't support creating connector at all. Switch to
drm_bridge_connector at the same time.

drm: Drop ARCH_MULTIPLATFORM from dependencies

2023-03-14T11:57:22+00:00

Some of these dependencies used to be sensible when only a small part of
the platforms supported by ARCH=arm could be compiled together in a
single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard
for kernel options incompatible with a multiplatform image. See commit
84fc86360623 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more
details.
