2022-07-29drm/mgag200: Remove type field from struct mga_deviceThomas Zimmermann1-3/+2
Each model's specific code is located in a separate file. The type field in struct mga_device is no unused. Remove it.

2022-07-29drm/mgag200: Move mode-config to model-specific codeThomas Zimmermann1-1/+110
Move the mode-config code into model-specific code and call the plane/CRTC helpers as needed. This will help with providing per- model implementations of individual helpers. Duplication of the pipeline init function is accepted. Some macros simplify this for shared helpers. v3: * clean up style Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220728124103.30159-13-tzimmermann@suse.de
2022-07-29drm/mgag200: Provide per-device callbacks for PIXPLLCThomas Zimmermann1-0/+59
Move the PIXPLLC code into per-model source files and wire it up with per-model callbacks. No functional changes. The PIXPLLC pixel-clock is part of the CRTC, but really separate hardware that varies with each model of the G200. Move the PIXPLLC code for each model into the per-model source file and call it from CRTC helpers via device functions. This allows to remove struct mgag200_pll and the related code. The new callbacks behave like the CRTC's atomic_check and atomic_enable functions. v3: * clean up style Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220728124103.30159-12-tzimmermann@suse.de

2022-07-29drm/mgag200: Move DAC-register setup into model-specific codeThomas Zimmermann1-0/+2
Provide an init function for each model's DAC registers. Remove the shared helper. The code for initializing the DAC registers consisted of a large table of default value, plus many exceptions for the various G200 models. Providing a per-model implementation makes if more readable. At some point, some of the initialization should probably move into the modesetting code. v2: * don't duplicate DAC values unnecessarily (Sam, Jocelyn) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220728124103.30159-3-tzimmermann@suse.de

2022-06-07drm/mgag200: Implement new init logicThomas Zimmermann1-5/+2
Rework mgag200_regs_init() and mgag200_mm_init() into device preinit and init functions. The preinit function, mgag200_device_preinit(), requests and maps a device's I/O and video memory. The init function, mgag200_device_init() initializes the state of struct mga_device. Splitting the initialization between the two functions is necessary to perform per-model operations between the two calls, such as reading the unique revision ID on G200SEs.
