7eb8f069be drm/exynos: add DSIM driver
The patch adds driver for Exynos DSI master (DSIM). It is a platform driver
which is registered as exynos_drm_display sub-driver of exynos_drm framework
and implements DRM encoder/connector pair.
It is also MIPI-DSI host driver and provides DSI bus for panels.
It interacts with its panel(s) using drm_panel framework.

1d96d4a677 drm/mipi_dsi: add flags to DSI messages
This patch adds flags field to mipi_dsi_msg structure and two flags:
- MIPI_DSI_MSG_REQ_ACK - request ACK from peripheral for given message,
- MIPI_DSI_MSG_USE_LPM - use Low Power Mode to transmit message.
The first flag is usually helpful during DSI diagnostic, the second
flag is required by some peripherals during configuration phase.

76c4b25008 drm/i915: move power domain init earlier during system resume
During resume the intel hda audio driver depends on the i915 driver
reinitializing the audio power domain. Since the order of calling the
i915 resume handler wrt. that of the audio driver is not guaranteed,
move the power domain reinitialization step to the resume_early
handler. This is guaranteed to run before the resume handler of any
other driver.

The power domain initialization in turn requires us to enable the i915
pci device first, so move that part earlier too.

Accordingly disabling of the i915 pci device should happen after the
audio suspend handler ran. So move the disabling later from the i915
resume handler to the resume_late handler.

v2:
- move intel_uncore_sanitize/early_sanitize earlier too, so they don't
  get reordered wrt. intel_power_domains_init_hw()

b65e64f7cc drm/cma: Use dma_mmap_writecombine() to mmap buffer
The GEM CMA helpers uses a custom mmap implementation based on
remap_pfn_range(). While this works when the buffer DMA and physical
addresses are identical, it fails to take IOMMU into account and tries
to mmap the buffer to userspace using the DMA virtual address instead of
the physical address. This results in mapping random physical pages when
the device is behind an IOMMU.

Use the DMA mapping dma_mmap_writecombine() function instead.

c683f427bd drm: Prefer noninterlace cmdline mode unless explicitly specified
Currently drm_pick_cmdline_mode() doesn't care about the interlace
when the given mode line has no "i" suffix.  That is, when there are
multiple entries for the same resolution, an interlace mode might be
picked up just depending on the assigned order, and there is no way to
exclude it.

This patch changes the logic for the mode selection, to prefer the
noninterlace mode unless the interlace mode is explicitly given.
When no matching mode is found, it still tries the interlace mode as
fallback.

In some cases, even the VRAM-fitting cases improved slightly (openarena, urban terror).

62347f9e0f drm: Add support for two-ended allocation, v3
Clients like i915 need to segregate cache domains within the GTT which
can lead to small amounts of fragmentation. By allocating the uncached
buffers from the bottom and the cacheable buffers from the top, we can
reduce the amount of wasted space and also optimize allocation of the
mappable portion of the GTT to only those buffers that require CPU
access through the GTT.

For other drivers, allocating small bos from one end and large ones
from the other helps improve the quality of fragmentation.

Based on drm_mm work by Chris Wilson.

v3: Changed to use a TTM placement flag
v2: Updated kerneldoc

057f6a8ad7 drm/i915: Invariably invalidate before ctx switch
We have been setting the bit which was originally BIOS dependent since:
commit f05bb0c7b6

    drm/i915: GFX_MODE Flush TLB Invalidate Mode must be '1' for scanline waits

Therefore, we do not need to try to figure it out dynamically and we can
just always invalidate the TLBs.

It's a partial revert of:
commit 12b0286f49

    drm/i915: possibly invalidate TLB before context switch

The original commit attempted to only invalidate when necessary
(very much a relic from the old days). Now, we can just always invalidate.

I guess the old TODO still exists. Since we seem to have abandoned ILK
contexts however, there isn't much point in even remembering.

0d95e11b7e drm/i915: Warn when DPIO read returns 0xffffffff
DPIO reads from groups/broadcast register offsets for PCS and
TX return all 1's. If that result gets used for something
we'll probably end up doing something wrong. So warn when that
happens.

FIXME there might be some registers where all 1's is a valid value,
so ideally we should check the register offset instead...

2070f00c79 drm/i915: Move DP M/N setup from update_pll to mode_set for gmch platforms
There's no point in hiding the DP M/N setup in the update_pll functions.
Just move it to the mode_set function.
