This allows us to remove the internal bit algo bus used by
the radeon i2c algo. We now register a radeon algo adapter
if the gpio line is hw capable and the hw inplementation is
available, otherwise we register a bit algo adapter.

We already know same offsets are used for different encoders/transmitters, so
just numeric them instead naming incorrectly. Additionaly we found additional

- add support for pre-avivo chips
- add support for fixed post/ref dividers
- add support for non-fractional fb dividers
By default avivo chips use the new algo and
pre-avivo chips use the old algo. Use the "new_pll"
module option to toggle between them.

Rework the pll algo selection so that the pll algo
in use can be selected more easily. This allows
us to select different pll divider selection algos
for specific monitors that work better with one algo
or the other. This is needed for the next patch which
adds an LVDS pll quirk for a specific notebook.

Some servers hardcode an edid in rom so that they will
work properly with KVMs. This is a port of the relevant

[airlied: reworked to validate edid at boot stage - and

booting a Lenovo W500 with LVDS + DP outputs showed up a TODO we had
on our list, to pick a correct digital encoder block. The LVTMA
encoder requires the second digital encoder, all others can use any
encoder at all.
This fixes the digital encoder selection logic to enable LVDS/DP combos
to work okay.
V2: fix silly addition of connector dig_block and cleanup the other
places in the code that pick the encoder.
V3: rename to dig_encoder and clean up further - also fix
the picking algorithm.
tested on Lenovo W500 + desktop 3650 cards.

R4xx mobility chips use atombios, which does not store
the LVDS_GEN_CNTL parameter setup like combios. Rather,
it's configured in LVDSEncoderControl. As such,
LVDS_GEN_CNTL is set wrong when on resume. Call
LVDSEncoderControl to set it properly.

Keep requested scaler type in radeon_encoder
and the actual scaler type used in radeon_crtc.
This prevents us from enabling the scaler when it's
not required (i.e., the requested mode is the native
mode). Also, always set the adjusted mode equal
to the native mode for lvds.
Should fix:

This enables initialization of external tmds chips on pre-atom

The previous patches had some unwanted side effects, I've fixed
the lack of 32bpp working, and fixed up 16bpp so it should also work.
this also adds the interface to allow the driver to set a preferred
console depth so for example low memory rn50 can set it to 8bpp.
It also catches 24bpp on cards that can't do it and forces 32bpp.
Tested on r100/r600/i945.

Initially I always meant this code to be shared, but things
ran away from me before I got to it.
This refactors the i915 and radeon kms fbdev interaction layers
out into generic helpers + driver specific pieces.
It moves all the panic/sysrq enhancements to the core file,
and stores a linked list of kernel fbs. This could possibly be
improved to only store the fb which has fbcon on it for panics
etc.
radeon retains some specific codes used for a big endian
workaround.

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).
