2020-08-03drm/mgag200: Clear <page> field during MM initThomas Zimmermann
The modesetting code initialized the memory-related register CRTCEXT4. Move this code to MM initialization.

2020-08-03drm/mgag200: Set MISC memory flags in mm init codeThomas Zimmermann
The modesetting code initialized several memory-related flags in the MISC register. Move this code to MM initialization.

2020-06-11drm/mgag200: Embed instance of struct drm_device in struct mga_deviceThomas Zimmermann
Following current best practice, the instance of struct drm_device is now embedded in struct mga_device. The respective field has been renamed from 'dev' to 'base' to reflect the relationship. Conversion from DRM device is done via upcast. Using dev_private is no longer possible. The patch also open-codes drm_dev_alloc() and DRM device initialization is now performed by a call to drm_device_init().

2020-06-11drm/mgag200: Switch to managed MMThomas Zimmermann
The memory-management code now cleans up automatically as part of device destruction. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200605135803.19811-8-tzimmermann@suse.de
2020-06-11drm/mgag200: Merge VRAM setup into MM initializationThomas Zimmermann
The VRAM setup in mgag200_drv.c is part of memory management and should be done in the same place. Merge the code into the memory management's init function.

2020-06-11drm/mgag200: Lookup VRAM PCI BAR start and length only onceThomas Zimmermann
The MM setup code on mgag200 reads PCI BAR 0's start and length several times. Reusing these values makes the code more readable.

2020-06-11drm/mgag200: Rename mgag200_ttm.c to mgag200_mm.cThomas Zimmermann
The mgag200 driver does not use TTM any longer. Rename the related file to mgag200_mm.c (as in 'memory management').
