bapm is a pm feature for sharing the power budget between
the GPU and the CPU on APUs. It needs to be enabled or
disabled in certain circumstances. For now, disable it
when on battery and enable it when on AC power.

The hwmon sysfs interface allows exposing temperature limits. The "max"
and "min" thresholds will be exposed as a critical high limit and its
hysteresis value, respectively. This gives the user a better idea of how
well cooling is doing and whether it is sufficient.

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 6f8bbaf568
(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.

Some older 6xx-7xx boards didn't always fill in the
UVD clocks properly in the UVD power states. This
leads to the driver trying to set a 0 clock which
results in slow or broken UVD playback.

Certain r6xx boards use the same power state for both UVD
and other things. Since we don't support UVD on r6xx boards
at the moment, there was no callback installed for setting
the UVD clocks, however, on systems that use the same power
state, this leads to a NULL pointer dereference. Fill
in a stubbed out implementation for now to avoid the crash.

The problem here is that "unsigned i" is always greater than or equal to
zero. These loops mostly have a second check for "(i == 0)" so only the
last two are actually buggy. The rest is just cleanup.
Bug 1: kv_force_dpm_highest() doesn't have an "(i == 0)" check so it's
a potential forever loop.
Bug 2: In kv_get_sleep_divider_id_from_clock() there is a typo and the
test is reversed "<=" vs ">" so we never enter the loop. That means
normally we return KV_MAX_DEEPSLEEP_DIVIDER_ID (5). The return value
from here is saved in ->DeepSleepDivId and I wasn't able to determine
how that is used. This is a static checker fix and I have not tested
it.

- Early stolen mem reservation from Jesse in x86 boot code. Acked by Ingo
and hpa. This was ready much earlier but somehow I've thought it'd go
in through x86 trees, hence why this is late. Avoids the pci resource
code to plant mmiobars in the middle of stolen mem and other ugliness.
- vgaarb improvements from Alex Williamson plus the fix from Ville for the
vgacon->fbcon smooth transition "feature".
- Render pageflips on ivb/hsw to avoid stalls due to the ring switching
when only flipping on the blitter (Chris).
- Deadlock fixes around our flush_workqueue which crept back in - lockdep
isn't clever enough :(
- Shrinker recursion fix from Chris - this is the thing that blew the vma
patches from Ben I've taken out of 3.12.
- Fixup for the relocation refactoring. Also an igt testcase to make sure
we don't break this again.
- Pile of smaller fixups all over, shortlog has full details.

When transitioning away from vgacon the system tries to save the
current contents of the VGA memory, so that it can be cleanly handed
off to fbcon (or whatever comes afterwards).

Author: Alex Williamson <alex.williamson@redhat.com>

i915: Update VGA arbiter support for newer devices
caused i915 to disable VGA memory decode for the IGD when i915 is
initializing. Unfortunately that happens before the vgacon->fbcon
handoff so vgacon_save_screen() will read out all ones from the
VGA memory.
After the handoff fbcon will inherit the bogus state from vgacon,
and pre-fills the fb with matching contents. The end result is
a white rectangle in the top left corner of the screen, the size
of which matches the now inactive VGA console.
To remedy the situation delay the disabling of VGA memory until
the vgacon->fbcon handoff has happened.
Also rename i915_enable_vga to i915_enable_vga_mem to make
the relationship between these functions clearer.

ACPI has _BCM and _BQC methods to set and query the backlight
brightness, respectively. The ACPI opregion has variables BCLP and CBLV
to hold the requested and current backlight brightness, respectively.
The BCLP variable has range 0..255 while the others have range
0..100. This means the _BCM method has to scale the brightness for BCLP,
and the gfx driver has to scale the requested value back for CBLV. If
the _BQC method uses the CBLV variable (apparently some implementations
do, some don't) for current backlight level reporting, there's room for
rounding errors.
Use DIV_ROUND_UP for scaling back to CBLV to get back to the same values
that were passed to _BCM, presuming the _BCM simply uses bclp = (in *
255) / 100 for scaling to BCLP.

This blew up while running kms_flip/flip-vs-panning-vs-hang-interruptible
on one of my older machines.
Unfortunately (despite the proper lockdep annotations for
flush_workqueue) lockdep still doesn't detect this correctly, so we
need to rely on chance to discover these bugs.
Apply the usual bugfix and schedule the reset work on the system
workqueue to keep our own driver workqueue free of any modeset lock
grabbing.
Note that this is not a terribly serious regression since before the
offending commit we'd simply have stalled userspace forever due to
failing to abort all outstanding pageflips.

Whilst running the shrinker, we need to hold a reference as we unbind
the objects, or else we may end up waiting for and retiring requests,
which in turn may result in this object being freed.
This is very similar to the eviction code which also has to be very
careful to keep a reference to its objects as it retires and unbinds
them.
Another similarity, that Ben pointed out, is that as we may call
retire-requests, the unbound_list is outside of our control. We must
only process a single element of that list at a time, that is we can not
rely on the "safe" next pointer being valid after a call to
i915_vma_unbind().

exynos_drm_connector.c now uses videomode helper API. Hence select
VIDEOMODE_HELPERS at DRM_EXYNOS level itself instead of at
DRM_EXYNOS_FIMD to avoid the following compilation error when FIMD
is not selected (introduced by commit cf796235a6 "drm/exynos: fimd:
replace struct fb_videomode with videomode"):
drivers/built-in.o: In function `exynos_drm_connector_get_modes':
drivers/gpu/drm/exynos/exynos_drm_connector.c:86:
undefined reference to `drm_display_mode_from_videomode'

Since commit 383ffda2fa ("ARM: EXYNOS: no more support non-DT
for EXYNOS SoCs"), Exynos platform is DT only. Hence remove
all the conditional macros and make the driver DT only.

To address the case where physically contiguous memory
MAY NOT be a mandatory requirement for framebuffer for
the application calling exynos_drm_gem_dumb_create,
the patch adds a feature to get non physically contiguous
memory for framebuffer, if physically contiguous memory
allocation fails and if IOMMU is supported.

The patch replaces all occurrences of struct fb_videomode by
more accurate struct videomode. The change allows to remove
mode conversion function and simplifies clock divider calculation.
Clock configuration is moved to separate function.

This patch checks if a requested window supports alpha channel or not.
In case of s3c64xx, window 0 doesn't support alpha channel so if
the request pixel format is ARGB8888 then change it to XRGB8888.

This patch fixes wrong pixel format setting.
A pixel format is decided according to bpp and depth, or user-requested
format but fimd driver considered only bpp value to decide a proper pixel
format. So this patch makes a proper pixel format to be set according
to drm_framebuffer's pixel_format which is set by addfb with bpp and
depth, or addfb2 with user-requested format.

The exynos4 platform is only dt-based since 3.10, we should convert driver data
and ids to dt-based parsing methods. The rotator driver has a limit table to get
size limit of input picture. Each SoCs has slightly different limit value
compared with any others.
For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have
8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size
for its X/Y axis. Thus, we should keep different tables for each of them.
This patch also includes desciptions of each nodes for the rotator and specifies
a example how to bind it.
