drm/ast: astdp: Fix timeout for enabling video signal

2025-01-28T13:31:50+00:00

The ASTDP transmitter sometimes takes up to 1 second for enabling the
video signal, while the timeout is only 200 msec. This results in a
kernel error message. Increase the timeout to 1 second. An example
of the error message is shown below.

This is a cosmetical problem. Enabling the video signal still works
even with the error message. The problem has always been present, but
only recent versions of the ast driver warn about missing the timeout.

drm: remove driver date from struct drm_driver and all drivers

2024-12-05T10:35:42+00:00

We stopped using the driver initialized date in commit 7fb8af6798e8
("drm: deprecate driver date") and (eventually) started returning "0"
for drm_version ioctl instead.

Finish the job, and remove the unused date member from struct
drm_driver, its initialization from drivers, along with the common
DRIVER_DATE macros.

v2: Also update drivers/accel (kernel test robot)

drm/ast: Use video aperture helpers

2024-10-14T13:28:47+00:00

DRM's aperture functions have long been implemented as helpers
under drivers/video/ for use with fbdev. Avoid the DRM wrappers by
calling the video functions directly.

drm/ast: Run DRM default client setup

2024-09-26T07:31:27+00:00

Call drm_client_setup() 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.

The ast driver specifies a preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

v5:
- select DRM_CLIENT_SELECTION
