Pull documentation updates from Jonathan Corbet:
"This was a not-too-busy cycle for documentation; highlights include:
- The beginnings of a set of translations into Spanish, headed up by
Carlos Bilbao
- More Chinese translations
- A change to the Sphinx "alabaster" theme by default for HTML
generation.
Unlike the previous default (Read the Docs), alabaster is shipped
with Sphinx by default, reducing the number of other dependencies
that need to be installed. It also (IMO) produces a cleaner and
more readable result.
- The ability to render the documentation into the texinfo format
(something Sphinx could always do, we just never wired it up until
now)
Plus the usual collection of typo fixes, build-warning fixes, and
minor updates"

Extend the DVB frontend parameter enums with additional values specified
by the DVB-C2 (ETSI EN 302 769) and DVB-S2X (ETSI EN 302 307-2)
standards to be ready for frontend drivers for such receivers.
While most parameters will be "read-only" due to being autodetected by
the receiver and only being reported back for informational purposes,
the addition of SYS_DVBC2 to the delivery systems enum is required,
because there are DVB-C2 capable receivers which are not capable of
DVB-C/C2 autodetection and thus need this enum value to be explicitly
instructed to search for a DVB-C2 signal.
As for DVB-S2X, as that is an extension to DVB-S2, the same delivery
system enum as for DVB-S2 can be used.
Add the additional enum values and comments to the documentation.

The V4L2 API historically allowed buffers to be queued with bytesused
set to 0 on output devices, in which case the driver would use the
buffer length. This behaviour is deprecated, and videobuf2 prints a
warning message in the kernel log. Drop it from the documentation.

This introduces support for the Aspeed JPEG format, where the new frame
can refer to previous frame to reduce the amount of compressed data.
The concept is similar to I/P frame of video compression. It will
compare the new frame with previous one to decide which macroblock's
data is changed, and only the changed macroblocks will be compressed.
This Aspeed JPEG format is used by the video engine on Aspeed platforms,
which is generally adapted for remote KVM.

The V4L2_CAP_ASYNCIO capability was never implemented (and in fact
it isn't clear what it was supposed to do in the first place).
Drop it from the capabilities list. Keep it in videodev2.h with the
other defines under ifndef __KERNEL__ for backwards compatibility.
This will free up a capability bit for other future uses. And having
an unused and undefined I/O method is just plain confusing.

array
Make explicit that V4L2_CID_STATELESS_HEVC_SLICE_PARAMS control is
a dynamic array control type.
Some drivers may be able to receive multiple slices in one control
to improve decoding performance.

The HEVC specification describes the following:
"PicOrderCntVal is derived as follows:
PicOrderCntVal = PicOrderCntMsb + slice_pic_order_cnt_lsb
The value of PicOrderCntVal shall be in the range of
−2^31 to 2^31 − 1, inclusive."
To match with these definitions change __u16 pic_order_cnt[2]
into __s32 pic_order_cnt_val.
Change v4l2_ctrl_hevc_slice_params->slice_pic_order_cnt to __s32 too.

Add a new flag that indicates that this control is a dynamically sized
array. Also document this flag.
Currently dynamically sized arrays are limited to one dimensional arrays,
but that might change in the future if there is a need for it.
The initial use-case of dynamic arrays are stateless codecs. A frame
can be divided in many slices, so you want to provide an array containing
slice information for each slice. Typically the number of slices is small,
but the standard allow for hundreds or thousands of slices. Dynamic arrays
are a good solution since sizing the array for the worst case would waste
substantial amounts of memory.

corresponding \begingroup command preceding it.

Some platforms with an Intel IPU3 have an IR sensor producing 10 bit
greyscale format data that is transmitted over a CSI-2 bus to a CIO2
device - this packs the data into 32 bytes per 25 pixels. Add an entry
to the uAPI header defining that format.

These two fields need documentation as they have dual meaning. It is also
confusing since pic_num is a derived value from frame_num, so this should
help application developers. If we ever need to make a V2 of this API, I
would suggest to remove pic_num entirely.
