f9df34f8cd [media] v4l: vsp1: Simplify frame end processing
The DRM pipeline, as it runs in automatic restart mode, never sees the
pipeline state set to VSP1_PIPELINE_STOPPING or VSP1_PIPELINE_STOPPED
when running the frame end interrupt handler. We can thus skip the
checks various checks in the handler and return immediately.

Similarly the DRM frame end handler calls vsp1_pipeline_run()
unnecessarily, as the state there is never VSP1_PIPELINE_STOPPED. Remove
the function call and the frame end handler is it's now empty.

45b46879a7 [media] media: Rename is_media_entity_v4l2_io to is_media_entity_v4l2_video_device
All users of is_media_entity_v4l2_io() (the exynos4-is, omap3isp,
davince_vpfe and omap4iss drivers and the v4l2-mc power management code)
use the function to check whether entities are video_device instances,
either to ensure they can cast the entity to a struct video_device, or
to count the number of video nodes users.

The purpose of the function is thus to identify whether the media entity
instance is an instance of the video_device object, not to check whether
it can perform I/O. Rename it accordingly, we will introduce a more
specific is_media_entity_v4l2_io() check when needed.

b76a2a8cb6 [media] media: Add obj_type field to struct media_entity
Code that processes media entities can require knowledge of the
structure type that embeds a particular media entity instance in order
to cast the entity to the proper object type. This needs is shown by the
presence of the is_media_entity_v4l2_io and is_media_entity_v4l2_subdev
functions.

The implementation of those two functions relies on the entity function
field, which is both a wrong and an inefficient design, without even
mentioning the maintenance issue involved in updating the functions
every time a new entity function is added. Fix this by adding add an
obj_type field to the media entity structure to carry the information.

1d260123cb [media] soc_camera: rcar_vin: add device tree support for r8a7792
Simply document new compatibility string.
As a previous patch adds a generic R-Car Gen2 compatibility string
there appears to be no need for a driver updates.

By documenting this compat string it may be used in DTSs shipped, for
example as part of ROMs. It must be used in conjunction with the Gen2
fallback compat string. At this time there are no known differences between
the r8a7792 IP block and that implemented by the driver for the Gen2
fallback compat string. Thus there is no need to update the driver as the
use of the Gen2 fallback compat string will activate the correct code in
the current driver while leaving the option for r8a7792-specific driver
code to be activated in an updated driver should the need arise.

bd546882ff [media] soc_camera: rcar_vin: add R-Car Gen 2 and 3 fallback compatibility strings
Add fallback compatibility string for R-Car Gen 1 and 2.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and 3. But beyond that it's unclear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

345900be58 [media] sh_mobile_ceu_camera: Remove dependency on SUPERH
A dependency on ARCH_SHMOBILE seems to be the best option for
sh_mobile_ceu_camera:

* For Super H based SoCs: sh_mobile_ceu is used on SH_AP325RXA, SH_ECOVEC,
  SH_KFR2R09, SH_MIGOR, and SH_7724_SOLUTION_ENGINE which depend on
  CPU_SUBTYPE_SH7722, CPU_SUBTYPE_SH7723, or CPU_SUBTYPE_SH7724 which all
  select ARCH_SHMOBILE.

* For ARM Based SoCs: Since the removal of legacy (non-multiplatform)
  support this driver has not been used by any Renesas ARM based SoCs.
  The Renesas ARM based SoCs currently select ARCH_SHMOBILE, however,
  it is planned that this will no longer be the case.

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

Thanks to Geert Uytterhoeven for analysis and portions of the
change log text.

166c5a6ef7 gma500: remove annoying deprecation warning
In commit e45708976a ("drm/dp-helper: Move the legacy helpers to
gma500") the legacy i2c helpers were moved to the only remaining user of
them, the gma500 driver.  Together with that move, i2c_dp_aux_add_bus()
was marked deprecated and started warning about its remaining use.

It's now been a year and a half of annoying warning, and apparently
nobody cares enough about gma500 to try to move it along to the more
modern models.

Get rid of the warning - if even the gma500 people don't care enough,
then they should certainly not spam other innocent developers with a
warning that might hide other, much more real issues.

4a2d057e4f Merge branch 'PAGE_CACHE_SIZE-removal'
Merge PAGE_CACHE_SIZE removal patches from Kirill Shutemov:
 "PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
  ago with promise that one day it will be possible to implement page
  cache with bigger chunks than PAGE_SIZE.

  This promise never materialized.  And unlikely will.

  Let's stop pretending that pages in page cache are special.  They are
  not.

  The first patch with most changes has been done with coccinelle.  The
  second is manual fixups on top.

  The third patch removes macros definition"

[ I was planning to apply this just before rc2, but then I spaced out,
  so here it is right _after_ rc2 instead.

  As Kirill suggested as a possibility, I could have decided to only
  merge the first two patches, and leave the old interfaces for
  compatibility, but I'd rather get it all done and any out-of-tree
  modules and patches can trivially do the converstion while still also
  working with older kernels, so there is little reason to try to
  maintain the redundant legacy model.    - Linus ]

* PAGE_CACHE_SIZE-removal:
  mm: drop PAGE_CACHE_* and page_cache_{get,release} definition
  mm, fs: remove remaining PAGE_CACHE_* and page_cache_{get,release} usage
  mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros
