drm/exynos: gem: Drop NONCONTIG flag for buffers allocated without IOMMU

2017-12-16T09:33:49+00:00

commit 120a264f9c2782682027d931d83dcbd22e01da80 upstream.

When no IOMMU is available, all GEM buffers allocated by Exynos DRM driver
are contiguous, because of the underlying dma_alloc_attrs() function
provides only such buffers. In such case it makes no sense to keep
BO_NONCONTIG flag for the allocated GEM buffers. This allows to avoid
failures for buffer contiguity checks in the subsequent operations on GEM
objects.

drm/exynos/decon5433: set STANDALONE_UPDATE_F on output enablement

[ Upstream commit 11d8bcef7a0399e1d2519f207fd575fc404306b4 ]

DECON_TV requires STANDALONE_UPDATE after output enabling, otherwise it does
not start. This change is neutral for DECON.

drm/i915: Prevent zero length "index" write

2017-12-05T10:22:52+00:00

commit 56350fb8978bbf4aafe08f21234e161dd128b417 upstream.

The hardware always writes one or two bytes in the index portion of
an indexed transfer. Make sure the message we send as the index
doesn't have a zero length.

drm/i915: Don't try indexed reads to alternate slave addresses

2017-12-05T10:22:51+00:00

commit ae5c631e605a452a5a0e73205a92810c01ed954b upstream.

We can only specify the one slave address to indexed reads/writes.
Make sure the messages we check are destined to the same slave
address before deciding to do an indexed transfer.

drm/panel: simple: Add missing panel_simple_unprepare() calls

2017-12-05T10:22:51+00:00

commit f3621a8eb59a913612c8e6e37d81f16b649f8b6c upstream.

During panel removal or system shutdown panel_simple_disable() is called
which disables the panel backlight but the panel is still powered due to
missing calls to panel_simple_unprepare().

drm/radeon: fix atombios on big endian

2017-12-05T10:22:51+00:00

commit 4f626a4ac8f57ddabf06d03870adab91e463217f upstream.

The function for byteswapping the data send to/from atombios was buggy for
num_bytes not divisible by four. The function must be aware of the fact
that after byte-swapping the u32 units, valid bytes might end up after the
num_bytes boundary.

This patch was tested on kernel 3.12 and allowed us to sucesfully use
DisplayPort on and Radeon SI card. Namely it fixed the link training and
EDID readout.

The function is patched both in radeon and amd drivers, since the functions
and the fixes are identical.

drm: Apply range restriction after color adjustment when allocation

2017-11-30T08:37:27+00:00

[ Upstream commit 3db93756b501e5f0a3951c79cfa9ed43c26d3455 ]

mm->color_adjust() compares the hole with its neighbouring nodes. They
only abutt before we restrict the hole, so we have to apply color_adjust
before we apply the range restriction.
