drm/radeon/atom: initialize more atom interpretor elements to 0

2013-09-10T00:57:18+00:00

commit 42a21826dc54583cdb79cc8477732e911ac9c376 upstream.

The ProcessAuxChannel table on some rv635 boards assumes
the divmul members are initialized to 0 otherwise we get
an invalid fb offset since it has a bad mask set when
setting the fb base.  While here initialize all the
atom interpretor elements to 0.

commit 402976fe51b2d1a58a29ba06fa1ca5ace3a4cdcd upstream.

On pre-R600 asics, the SpeedFanControl table is not
executed as part of ASIC_Init as it is on newer asics.

drm/radeon/kms/atom: fix handling of FB scratch indices

2011-10-19T08:47:47+00:00

FB scratch indices are dword indices, but we were treating
them as byte indices.  As such, we were getting the wrong
FB scratch data for non-0 indices.  Fix the indices and
guard the indexing against indices larger than the scratch
allocation.

Fixes memory corruption on some boards if data was written
past the end of the FB scratch array.

drivers/gpu/drm/radeon/atom.c: fix warning

2011-05-23T23:00:37+00:00

udelay() doesn't like 8-bit arguments:

drivers/gpu/drm/radeon/atom.c: In function 'atom_op_delay':
drivers/gpu/drm/radeon/atom.c:653: warning: comparison is always false due to limited range of data type

while we're there, use msleep() rather than open-coding it.
