drm/ast: make ast_modeset static

2022-09-26T07:11:47Z

The symbol is not used outside of the file, so mark it static. Fixes the following warning: drivers/gpu/drm/ast/ast_drv.c:42:5: warning: symbol 'ast_modeset' was not declared. Should it be static?

drm/atomic-helper: Remove _HELPER_ infix from DRM_PLANE_HELPER_NO_SCALING

2022-07-26T16:42:00Z

Rename DRM_PLANE_HELPER_NO_SCALING to DRM_PLANE_NO_SCALING. The constant is not really a helper, but rather a characteristic of the plane itself.

drm/atomic-helper: Move DRM_PLANE_HELPER_NO_SCALING to atomic helpers

2022-07-26T16:41:56Z

The macro DRM_PLANE_HELPER_NO_SCALING is only useful with the interfaces in drm_atomic_helper.h, but defined in drm_plane_helper.h. So half of DRM includes the latter header file for using this macro. Move the macro and remove the include statements.

drm/ast: Enable primary plane with CRTC

2022-06-27T09:10:43Z

As the CRTC requires a primary plane for display, ensure that the primary plane is enabled with the CRTC. Use drm_atomic_helper_check_crtc_state(). Add all affected planes to the atomic state so that their state will be checked as well.

drm/ast: Fix black screen when getting out of suspend

2022-06-27T08:15:02Z

With an AST2600, the screen is garbage when going out of suspend. This is because color settings are lost, and not restored on resume. Force the color settings on DPMS_ON, to make sure the settings are correct.

drm: Drop drm_edid.h from drm_crtc.h

2022-06-20T20:53:55Z

drm_crtc.h has no need for drm_edid.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_edid.h. Quite a few placs do currently depend on drm_edid.h without actually including it directly.

drm/ast: Support multiple outputs

2022-06-08T11:16:15Z

Systems with AST graphics can have multiple output; typically VGA plus some other port. Record detected output chips in a bitmask and initialize each output on its own. Assume a VGA output by default and use SIL164 and DP501 if available. For ASTDP assume that it can run in parallel with VGA. Tested on AST2100. v3: * define a macro for each BIT(ast_tx_chip) (Patrik) v2: * make VGA/SIL164/DP501 mutually exclusive Signed-off-by: Thomas Zimmermann Reviewed-by: Patrik Jakobsson Fixes: a59b026419f3 ("drm/ast: Initialize encoder and connector for VGA in helper function") Cc: Thomas Zimmermann Cc: Javier Martinez Canillas Cc: Dave Airlie Cc: dri-devel@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20220607092008.22123-2-tzimmermann@suse.de
