Alex Deucher 9f998ad7e9 drm/radeon/kms: minor fixes for eDP with LCD* device tags (v2)
Some systems have LCD* rather than DFP* device tags in the bios
for eDP connectors; notably the new apple iMac. This fixes
things up so eDP connectors with either tag will work.

v2: fix typo

Alex Deucher 5f77df368c drm/radeon/r6xx/r7xx: CS parser fixes
- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs.  This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.

When there is allocation failure in radeon_cs_parser_relocs parser->nrelocs
is not cleaned. This causes NULL pointer defeference in radeon_cs_parser_fini
when clean up code is trying to loop over the relocation array and free the
objects.

Fix adds a check for a possible NULL pointer in clean up code.

Alex Deucher 65388342d6 drm/radeon/r600: add missing license and comments to r600_blit_shaders.c
R6xx+ cards need to use the 3D engine to blit data which requires
quite a bit of hw state setup.  Rather than pull the whole 3D driver
(which normally generates the 3D state) into the DRM, we opt to use
statically generated state tables.  The regsiter state and shaders
were hand generated to support blitting functionality.  See the 3D
driver or documentation for descriptions of the registers and
shader instructions.

Rafał Miłecki 5715f67cec drm/radeon/kms: add HDMI code for pre-DCE3 R6xx GPUs
Older GPUs are little different, HDMI blocks are not hard-wired, but routable.
We should just find some free HDMI block and route it to choosen encoder. In
case of RS6x0 there is only one HDMI block, we don't enable HDMI on RS6x00 yet
however.

Rafał Miłecki 2cd6218cb8 drm/radeon/kms: clean assigning HDMI blocks to encoders
We almost always used first HDMI block for first encoder and second for sencod.
Exception was KLDSCP_LVTMA. Analyzing code picking DIG encoder shows the same
behaviour. It shows HDMI block are related to DIGs, which relation we now use.

Rafał Miłecki 808032ee29 drm/radeon/kms: clean HDMI definitions
We already know same offsets are used for different encoders/transmitters, so
just numeric them instead naming incorrectly. Additionaly we found additional
registers needed for RV770+
