drm/mgag200: Embed connector instance in struct mga_device

2020-05-11T14:40:44+00:00

Storing the connector instance in struct mga_device avoids some dynamic memory allocation. On errors, the connector's initializer function now destroys the i2c structure. Done in preparation of converting mgag200 to simple-KMS helpers. v2: * improved commit message (Michael) * fixed error message for mgag200_vga_connector_init() (Sam) Signed-off-by: Thomas Zimmermann Reviewed-by: Michael J.

drm/mgag200: Remove unused fields from struct mga_device

The fields mode_info, num_crtcs and mode in struct mga_device serve no purpose. Remove them. Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Tested-by: John Donnelly Link: https://patchwork.freedesktop.org/patch/msgid/20200507090315.21274-6-tzimmermann@suse.de

drm/mgag200: Use managed mode-config initialization

drm/mgag200: Convert struct drm_device to struct mga_device with helper

2020-05-11T14:39:45+00:00

Mgag200 uses dev_private to look up struct mga_device for instances of struct drm_device. Use of dev_private is deprecated, so hide it in the helper function to_mga_device(). v2: * make to_mga_device() a function (Sam) Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20200507090315.21274-2-tzimmermann@suse.de

drm/mgag200: Set up fbdev after registering device; remove error checks

2020-04-08T14:24:52+00:00

Generic fbdev support is a DRM client. Set it up after registering the new DRM device. Remove the error checks as the driver's probe function should not depend on a DRM client's state.

drm/mgag200: Use simple encoder

drm/vram-helper: Remove BO device from public interface

2020-01-07T10:53:19+00:00

TTM is an implementation detail of the VRAM helpers and therefore shouldn't be exposed to the callers. There's only one correct value for the BO device anyway, which is the one stored in the DRM device. So remove struct ttm_bo_device from the VRAM-helper interface and use the device's VRAM manager unconditionally. The GEM initializer function fails if the VRAM manager has not been initialized.
