commit 6802d4bad83f50081b2788698570218aaff8d10e upstream.
The BlankCrtc table in some DCE8 boards has some
logic shortcuts for the vbios when this bit is set.
Clear it for driver use.

commit 3e71985f2439d8c4090dc2820e497e6f3d72dcff upstream.
The values were taken from the HDMI spec, but they assumed
exact x/1.001 clocks. Since we round the clocks, we also need
to calculate different N and CTS values.
Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of
spec. Hopefully this mode is rarely used and/or HDMI sinks
tolerate overly large values of N.

This reverts commit b2a9484006875ecd7d94582e7bcb72a02682be92.

b2a9484006875ecd7d94582e7bcb72a02682be92) was supposed to fix rv6xx_asic
struct.
In kernel 3.10 we didn't have that struct yet, so the original patch
should never be backported to the 3.10. Accidentally it has applied and
modified different struct (r520_asic) that shouldn't have any HDMI
callbacks at all.

commit 91f3a6aaf280294b07c05dfe606e6c27b7ba3c72 upstream.
The OUTPUT_ENABLE action jumps past the point in the coder where
the data_offset is set on certain rs780 cards. This worked
previously because the OUTPUT_ENABLE action is always called
immediately after the ENABLE action so the data_offset remained
set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57
(drm/radeon/atom: initialize more atom interpretor elements to 0),
we explictly reset data_offset to 0 between atom calls which then
caused this to fail. The fix is to just skip calling the
OUTPUT_ENABLE action on the problematic chipsets. The ENABLE
action does the same thing and more. Ultimately, we could
probably drop the OUTPUT_ENABLE action all together on DCE3
asics.

commit e5b9e7503eb1f4884efa3b321d3cc47806779202 upstream.
Also add a new RADEON_INFO query to check that CP DMA packets are
supported on the compute ring.
CP DMA has been supported since the 3.8 kernel, but due to an oversight
we forgot to teach the CS checker that the CP DMA packet was legal for
the compute ring on Southern Islands GPUs.
This patch fixes a bug where the radeon driver will incorrectly reject a legal
CP DMA packet from user space. I would like to have the patch
backported to stable so that we don't have to require Mesa users to use a
bleeding edge kernel in order to take advantage of this feature which
is already present in the stable kernels (3.8 and newer).
