drm/ast: Support device quirks

2025-10-15T07:59:41Z

Define struct ast_device_quirks and add an instance for each hardware generation. The type will provide information about per-gen constants and oddities. Signed-off-by: Thomas Zimmermann Reviewed-by: Jocelyn Falempe > Link: https://lore.kernel.org/r/20251007150343.273718-3-tzimmermann@suse.de

drm/ast: Remove generic device initialization

2025-09-29T11:28:16Z

The code in ast_main.c has been split into several helpers in other source files. Delete the source file. With the generic device init gone, fail probing on unknown hardware generations.

drm/ast: Move Gen7 device initialization into separate helper

2025-09-29T11:28:16Z

Split off device initialization for Gen7 hardware into the helpers ast_2600_device_create() and ast_2600_detect_wide_screen(). The new functions are duplicates of their counterparts in ast_main.c, but stripped from most non-Gen7 support. Simplifies maintenance as the driver's number of supported hardware generations grows.

drm/ast: Prepare per-Gen device initialization

2025-09-29T11:28:10Z

Switch device creation by hardware Gen. Return the value from the call to ast_detect_chip(). All generations are still initialized by ast_device_create(). Also add ast_device_init() for setting some common fields in struct ast_device.
