DT properties dual-lvds-even-pixels and dual-lvds-odd-pixels
can be used to work out if the driver needs to swap even
and odd pixels around.

This patch makes use of the return value from function
drm_of_lvds_get_dual_link_pixel_order to determine if we
need to swap odd and even pixels around for things to work
properly.

The dual_link boolean field from struct rcar_lvds is not
sufficient to describe the type of LVDS link anymore, since
we now have information related to pixel order, therefore
rename it to link_type and repurpose its usage to fit the
new requirements.

An LVDS dual-link connection is made of two links, with even
pixels transitting on one link, and odd pixels on the other
link. The device tree can be used to fully describe dual-link
LVDS connections between encoders and bridges/panels.
The sink of an LVDS dual-link connection is made of two ports,
the corresponding OF graph port nodes can be marked
with either dual-lvds-even-pixels or dual-lvds-odd-pixels,
and that fully describes an LVDS dual-link connection,
including pixel order.

drm_of_lvds_get_dual_link_pixel_order is a new helper
added by this patch, given the source port nodes it
returns DRM_LVDS_DUAL_LINK_EVEN_ODD_PIXELS if the source
port nodes belong to an LVDS dual-link connection, with even
pixels expected to be generated from the first port, and odd
pixels expected to be generated from the second port.
If the new helper returns DRM_LVDS_DUAL_LINK_ODD_EVEN_PIXELS,
odd pixels are expected to be generated from the first port,
and even pixels from the other port.

The R-Car LVDS encoder driver implements the bridge .mode_set()
operation for the sole purpose of storing the mode in the LVDS private
data, to be used later when enabling the encoder.

Switch to the bridge .atomic_enable() and .atomic_disable() operations
in order to access the global atomic state, and get the mode from the
state instead. Remove both the unneeded .mode_set() operation and the
display_mode and mode fields storing state data from the rcar_lvds
private structure.

As a side effect we get the CRTC from the state, replace the CRTC
pointer retrieved through the bridge's encoder that shouldn't be used by
atomic drivers.

While at it, clarify a few error messages in rcar_lvds_get_lvds_mode()
and turn them into warnings as they are not fatal.

  parameters (char *dir_name, unsigned long flags) are passed by
  ksys_mount() to do_mount() unchanged, and therefore do not require
  particular care.

  Moreover, instead of pretending to be userspace, the opening of
  /dev/console as stdin/stdout/stderr can be implemented using in-kernel
  functions as well. Thereby, ksys_dup() can be removed for good"

[ This doesn't get rid of the special "kernel init runs with KERNEL_DS"

Pull char/misc driver fixes from Greg KH:
 "Here are six small fixes for some reported char/misc driver issues:

   - fix build warnings with new 'awk' with the raid6 code

   - four interconnect driver bugfixes

   - binder fix for reported problem

  All of these except the binder fix have been in linux-next with no
  reported issues. The binder fix is "new" but Todd says it is good as
  he has tested it :)"

Pull driver core fixes from Greg KH:
 "Here are two small driver core fixes to resolve some reported issues

  The first is to handle the much-reported (by the build systems)
  problem that superH does not boot anymore.

  The second handles an issue in the new platform logic that a number of
  people ran into with the automated tests in kbuild

  Both of these have been in linux-next with no reported issues"

Pull staging/IIO fixes from Greg KH:
 "Here are a number of small staging and IIO driver fixes for reported
  issues for 5.5-rc2

  Nothing major, a bunch of tiny IIO driver issues resolved, and some
  staging driver fixes for things that people ran into with 5.5-rc1.
  Full details are in the shortlog.

  All of these have been in linux-next with no reported issues"
