[media] media: Support Intersil/Techwell TW686x-based video capture cards
This commit introduces the support for the Techwell TW686x video
capture IC. This hardware supports a few DMA modes, including
scatter-gather and frame (contiguous).
This commit makes little use of the DMA engine and instead has
a memcpy based implementation. DMA frame and scatter-gather modes
support may be added in the future.
Currently supported chips:
- TW6864 (4 video channels),
- TW6865 (4 video channels, not tested, second generation chip),
- TW6868 (8 video channels but only 4 first channels using
built-in video decoder are supported, not tested),
- TW6869 (8 video channels, second generation chip).

since sometimes, it is protected via a spin lock, while, for
media graph traversal, it is protected by a mutex.

[media] v4l: vsp1: Document calling context of vsp1_pipeline_propagate_alpha()
The function can only be called from a s_stream handler as it requires a
valid display list context (due to calling vsp1_uds_set_alpha() which
writes to module registers). Document the requirement.
The RPF source memory pointers need to be offset to take the crop
rectangle into account. Offsets are computed in the RPF stream start,
which can happen (when using the DRM pipeline) after calling the RPF
.set_memory() operation that programs the buffer addresses.
The .set_memory() operation tries to guard against the problem by
skipping programming of the registers when the module isn't streaming.
This will however only protect the first use of an RPF in a DRM
pipeline, as in all subsequent uses the module streaming flag will be
set and the .set_memory() operation will use potentially incorrect
offsets.
Fix this by allowing the caller to decide whether to program the
hardware immediately or just cache the addresses. While at it refactor
the memory set code and create a new vsp1_rwpf_set_memory() that cache
addresses and calls the .set_memory() operation to apply them to the
hardware.
As a side effect the driver now writes all three DMA address registers
regardless of the number of planes, and initializes unused addresses to
zero.

In commit e45708976aea ("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.

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 ]
