drm/ast: Remove generic device initialization

2025-09-29T11:28:16+00:00

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 Gen5 device initialization into separate helper

2025-09-29T11:28:14+00:00

Split off device initialization for Gen5 hardware into the helpers ast_2400_device_create() and ast_2400_detect_wide_screen(). The new functions are duplicates of their counterparts in ast_main.c, but stripped from most non-Gen5 support. Simplifies maintenance as the driver's number of supported hardware generations grows. v2: - simplify widescreen-detection logic Signed-off-by: Thomas Zimmermann Reviewed-by: Jocelyn Falempe Link: https://lore.kernel.org/r/20250922083708.45564-10-tzimmermann@suse.de

drm/ast: Move Gen2+ and Gen1 POST code to separate source files

2025-07-09T12:36:18+00:00

Move POST code for Gen2+ and Gen1 to separate source files and hide it in ast_2100_post() ans ast_2000_post(). With P2A configuration, the POST logic for these chip generations has been mingled in ast_init_dram_reg(). Hence, handle all generations in a single change. The split simplifies both cases. Also move the DRAM init tables for each Gen into the respective source file. No changes to the overall logic.

drm/ast: Move Gen4+ POST code to separate source file

2025-07-09T12:36:17+00:00

Move POST code for Gen4+ to separate source file and hide it in ast_2300_post(). With P2A configuration, it performs a full board POST and enables the transmitter chip; otherwise it only enables the transmitter chip. Also fix coding style in several places. No changes to the overall logic. Signed-off-by: Thomas Zimmermann Reviewed-by: Jocelyn Falempe Link: https://lore.kernel.org/r/20250706162816.211552-5-tzimmermann@suse.de

drm/ast: Add helpers for VBIOS mode lookup

2025-02-03T13:01:12+00:00

Mode lines are independent from hardware Gen or TX chip, so hide all VBIOS mode tables in ast_vbios.c. Move the look-up code for VBIOS modes from ast_vbios_get_mode_info() to ast_vbios_find_mode(). The new look-up function respects the supported-mode flags in struct ast_device. For example, if a device does not have struct ast_device.support_fullhd set, the helper does not return a valid mode for 1920x1080. Taking the supported-mode flags into account allows for making the VBIOS tables the single reference for validating and setting display modes against hardware capabilities. v2: - replace mode switch with look-up table (Jocelyn) Signed-off-by: Thomas Zimmermann Reviewed-by: Jocelyn Falempe Link: https://patchwork.freedesktop.org/patch/msgid/20250131092257.115596-11-tzimmermann@suse.de
