drm/nv04/crtc: Bail out if FB is not bound to crtc
drm/nouveau: fix nv04_sgdma_bind on non-"4kB pages" archs
drm/nouveau: properly handle allocation failure in nouveau_sgdma_populate
drm/nouveau: fix oops on pre-semaphore hardware
drm/nv50/crtc: Bail out if FB is not bound to crtc
nv04_sgdma_bind binds the same page multiple times on
architectures where PAGE_SIZE != 4096.
Let's fix it.

Not cleaning after alloc failure would result in crash on destroy,
because nouveau_sgdma_clear assumes "ttm_alloced" to be not null when
"pages" is not null.

Sink type is always DP for DP bridges and EDID fetch on
DP bridges is always i2c over aux rather than plain i2c.

On some Power rv100 cards, we have no ATY OF table, but we have
no combios table either, and hence we refuse all modes on VGA-0
since we end up with a 0 max pixel clock.

For some reason SPI block is in broken state after module
unloading. This lead to broken rendering after reloading
module. Fix this by reseting SPI block in CP resume function

drm/i915: Fix wrong initializer for "locked" variable in assert_panel_unlocked
i915: do not setup intel_backlight twice
Toshiba Satellite L300D with ATI Mobility Radeon X1100 sends data
to i2c bus for a HDMI connector that is not implemented/existent
on the notebook's board.
Fix by applying extented DDC probing for this connector.
Requires [PATCH] drm/radeon: Extended DDC Probing for Connectors
with Improperly Wired DDC Lines
Tested for kernel 2.6.38 on Toshiba Satellite L300D notebook

This was true for new TTM_PL_SYSTEM and new TTM_PL_TT cases, but wasn't
the case on TTM_PL_SYSTEM<->TTM_PL_TT moves, which causes trouble on some
paths as nouveau's move_notify() hook requires that the dma addresses be
valid at this point.

Nouveau makes the assumption that if a TTM is bound there will be a mm_node

The commit "Not all systems expose a firmware or platform mechanism for
changing the backlight intensity on i915, so add native driver support"
adds calls to intel_panel_setup_backlight() from intel_{lvds,dp}_init
so do not call it again from intel_setup_outputs().

Alpha needs to have available the system bus address for the Radeon's
local memory, so that it can be used in ttm_bo_vm_fault(), when building
the PTEs for accessing that VRAM. So, we make bus.addr hold the ioremap()
return, and then we can modify bus.base appropriately for use during page
fault processing.
