Update extcon for 4.17
Detailed description for this pull request:
1. Add exported extcon function in order to support OF graph binding
- The extcon consumer driver used the "extcon = <&extcon's phandle"
property in device-tree in order to bind between extcon provider
and consumer driver. But, OF graph method is better than 'extcon' property.
So, extcon subsystem adds the following function to support OF graph binding.
: extcon_find_edev_by_node(struct device_node *node)
- Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
and device-tree subsystem. This immutable branch contains the use-case of
OF graph binding for EXTCON_HDMI connector between MHL device driver
and extcon provider driver.
2. Fix minor issues of extcon device drivers
- Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
- Remove workaround code for id pin direction from extcon-inte-int3496.c
because GPIO ACPI library does support it with generic way.
- Set direction and drv flags for V5 boost GPIO because of fixing
the firmware bug.
When validating legacy surfaces, the backup bo might be destroyed at
surface validate time. However, the kms resource validation code may have
the bo reserved, so we will destroy a locked mutex. While there shouldn't
be any other users of that mutex when it is destroyed, it causes a lock
leak and thus throws a lockdep error.
Fix this by having the kms resource validation code hold a reference to
the bo while we have it reserved. We do this by introducing a validation
context which might come in handy when the kms code is extended to validate
multiple resources or buffers.

When we are running without fbdev, transitioning from the login screen to
X or gnome-shell/wayland will cause a vt switch and the driver will disable
svga mode, losing all modesetting resources. However, the kms atomic state
does not reflect that and may think that a crtc is still turned on, which
will cause device errors when we try to bind an fb to the crtc, and the
screen will remain black.
Fix this by turning off all kms resources before disabling svga mode.

This patch adds support to detect ICL, slice, subslice and EU fuse
settings.
Add addresses for ICL 11 slice, subslice and EU fuses registers.
These register addresses are the same as previous platforms but the
format and / or the meaning of the information is different. Therefore
Gen11 defines for these registers are added.
Bspec: 9731
Bspec: 20643
Bspec: 20673
v2: Update fusing information storage after introducing the new query
uAPI (Lionel)
v3 (Oscar):
- The maximum number of slices in ICL 11 is 1
- The subslice disable fuse can potentially store information in
all bits
- GEN_MAX_SUBSLICES has to be increased to 8
- Don't trust the slice enabled fuse outside the max number of
expected slices
- Indentation fix and some reordering and renaming of local
variables
v4: Use single space after Cc tag

Replace drm_gem_object_reference/unreference function with *_get/put()

The truncation isn't being programmed if the truncation
depth is set to 2, it causes an issue with dce11.2 asic
using 6bit eDP panel. It required to truncate 12:10 in order to
perform spatial dither 10:6.
This change will allow 12:10 truncation to be enabled.

Updates for 4.17. Sorry, running a bit late on this, didn't have a
chance to send pull-req before heading to linaro. But it has all been
in linux-next for a while. Main updates:
+ DSI updates from 10nm / SDM845
+ fix for race condition with a3xx/a4xx fence completion irq
+ some refactoring/prep work for eventual a6xx support (ie. when we have
a userspace)
+ a5xx debugfs enhancements
+ some mdp5 fixes/cleanups to prepare for eventually merging writeback
support (ie. when we have a userspace)

drm/tegra: Changes for v4.17-rc1
This fixes mmap() for fbdev devices by providing a custom implementation
based on the KMS variant. This is a fairly exotic case these days, hence
why it is not flagged for stable.
There is also support for dedicating one of the overlay planes to serve
as a hardware cursor on older Tegra that did support hardware cursors
but not RGBA formats for it.
Planes will now also export the IN_FORMATS property by supporting the
various block-linear tiling modifiers for RGBA pixel formats.
Other than that, there's a bit of cleanup of DMA API abuse, use of the
private object infrastructure for global state (rather than subclassing
atomic state objects) and an implementation of ->{begin,end}_cpu_access
callbacks for PRIME exported buffers, which allow users to perform cache
maintenance on these buffers.

drm/tegra: Fixes for v4.16-rc7
This contains two small fixes for the alpha blending support that was
merged into v4.16-rc1 and a fix for connector reference leaks caused by
the fact that display pipelines are no longer automatically disabled if
the framebuffer is removed.
Furthermore this contains a fix for a crash on IOMMU detach at driver
unbind time and a regulator enable/disable unbalance fix.

Not all callers want the GPU error to handled in the same way, so expose
a control parameter. In the first instance, some callers do not want the
heavyweight error capture so add a bit to request the state to be
captured and saved.
v2: Pass msg down to i915_reset/i915_reset_engine so that we include the
reason for the reset in the dev_notice(), superseding the earlier option
to not print that notice.
v3: Stash the reason inside the i915->gpu_error to handover to the direct
reset from the blocking waiter.
