Alex Deucher bcc1c2a1d2 drm/radeon/kms: add initial Evergreen support (Radeon HD 5xxx)
This adds initial Evergreen KMS support, it doesn't include
any acceleration features or interrupt handling yet.

Major changes are DCE4 handling for PLLs for the > 2 crtcs.

Alex Deucher 6d7f2d8da1 drm/radeon/kms: dynclks fixes
- only r4xx/r5xx/rs6xx/rs740 have clock gating atom table,
so disable it on r6xx.  it's already disabled on r7xx
- check to make sure the clock_gating hook exists before
calling it.  This avoids a segfault on asics without
that function.
- remove unused static power management function.

Alex Deucher 2a008d0ccd drm/radeon/kms: more r4xx lvds fixes
Grab pll ref div from regs at driver init.  r4xx seems very
picky about the dividers for the pll driving lvds.

Jerome Glisse 3ce0a23d2d drm/radeon/kms: add r600 KMS support
This adds the r600 KMS + CS support to the Linux kernel.

The r600 TTM support is quite basic and still needs more
work esp around using interrupts, but the polled fencing
should work okay for now.

Also currently TTM is using memcpy to do VRAM moves,
the code is here to use a 3D blit to do this, but
isn't fully debugged yet.

Jerome Glisse 771fe6b912 drm/radeon: introduce kernel modesetting for radeon hardware
Add kernel modesetting support to radeon driver, use the ttm memory
manager to manage memory and DRM/GEM to provide userspace API.
In order to avoid backward compatibility issue and to allow clean
design and code the radeon kernel modesetting use different code path
than old radeon/drm driver.

When kernel modesetting is enabled the IOCTL of radeon/drm
driver are considered as invalid and an error message is printed
in the log and they return failure.

KMS enabled userspace will use new API to talk with the radeon/drm
driver. The new API provide functions to create/destroy/share/mmap
buffer object which are then managed by the kernel memory manager
(here TTM). In order to submit command to the GPU the userspace
provide a buffer holding the command stream, along this buffer
userspace have to provide a list of buffer object used by the
command stream. The kernel radeon driver will then place buffer
in GPU accessible memory and will update command stream to reflect
the position of the different buffers.

The kernel will also perform security check on command stream
provided by the user, we want to catch and forbid any illegal use
of the GPU such as DMA into random system memory or into memory
not owned by the process supplying the command stream. This part
of the code is still incomplete and this why we propose that patch
as a staging driver addition, future security might forbid current
experimental userspace to run.

This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX
(radeon up to X1950). Works is underway to provide support for R6XX,
R7XX and newer hardware (radeon from HD2XXX to HD4XXX).
