drm/radeon/kms: add dynamic engine reclocking (V9)
V2: reorganize functions, fix modesetting calls V3: rebase patch, use radeon's workqueue V4: enable on tested chipsets only, request VBLANK IRQs V5: enable PM on older hardware (IRQs, mode_fixup, dpms) V6: use separate dynpm module parameter V7: drop RADEON_ prefix, set minimum mode for dpms off V8: update legacy encoder call, fix order in rs600 IRQ V9: update compute_clocks call in legacy, not only DPMS_OFF Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
