drm: Include iff CONFIG_AGP is set

2021-05-11T12:13:33+00:00

Platforms without AGP don't provide the AGP header. Only include it
if CONFIG_AGP is set.

drm: Mark AGP implementation and ioctls as legacy

2021-05-10T13:46:58+00:00

Only UMs drivers use DRM's core AGP code and ioctls. Mark the icotls
as legacy. Add the _legacy_ infix to all AGP functions. Move the
declarations to the public and internal legacy header files. The agp
field in struct drm_device is now located in the structure's legacy
section. Adapt drivers to the changes.

AGP code now depends on CONFIG_DRM_LEGACY.

drm: Upcast struct drm_device.dev to struct pci_device; replace pdev

2021-01-19T08:06:38+00:00

We have DRM drivers based on USB, SPI and platform devices. All of them
are fine with storing their device reference in struct drm_device.dev.
PCI devices should be no exception. Therefore struct drm_device.pdev is
deprecated.

Instead upcast from struct drm_device.dev with to_pci_dev(). PCI-specific
code can use dev_is_pci() to test for a PCI device. This patch changes
the DRM core code and documentation accordingly.

	* split-off pdev deprecation into separate patch

drm: Inline AGP wrappers into their only callers

2021-01-13T13:21:53+00:00

The AGP wrapper functions serve no purpose. They used to handle
builds that have CONFIG_AGP unset. But their callers are all in
drm_agpsupport.c, which only gets build with CONFIG_AGP.

The opening comment mark "/**" is reserved for kernel-doc comments, so

Most of these are just cases where code comments used contractions
