address it is still allowed to send a message from 0xf (Unregistered)

The xvYCC601/709 encodings were mapped by default to full range quantization.
This is actually wrong since these encodings use limited range quantization,
but accept values outside of the limited range.
This makes sense since for values within the limited range it behaves exactly
the same as BT.601 or Rec. 709. The only difference is that with the xvYCC
encodings the values outside of the limited range also produce value colors.
Talking to people who know a lot more about this than I do made me realize
that mapping xvYCC to full range quantization was wrong, so this patch corrects
this and also improves the documentation.
These formats are very rare, and since the formula for decoding these Y'CbCr
encodings is actually fixed and independent of the quantization field value
it is safe to make this change.
The main advantage is that keeps the V4L2 specification in sync with the
corresponding colorspace, HDMI and CEA861 standards when it comes to these
xvYCC formats.

The DT bindings assumed that this IP block was coming from
Cortina Systems, which turns out not to be true. It is a
standard IP block from Faraday Technology and also used in the
Moxa moxart SoC.
We augment the bindings to cover all existing parts and rename
it after the IP block. This involves deleting the old Moxa
bindings that now are contained in this binding.

This patch adds support for ECMP hash policy choice via a new sysctl
called fib_multipath_hash_policy and also adds support for L4 hashes.
The current values for fib_multipath_hash_policy are:
0 - layer 3 (default)
1 - layer 4
If there's an skb hash already set and it matches the chosen policy then it
will be used instead of being calculated (currently only for L4).
In L3 mode we always calculate the hash due to the ICMP error special
case, the flow dissector's field consistentification should handle the
address order thus we can remove the address reversals.
If the skb is provided we always use it for the hash calculation,
otherwise we fallback to fl4, that is if skb is NULL fl4 has to be set.

7) Remove unnecessary rcu read lock side in bridge netfilter, from
Florian Westphal.
8) Remove unused variable in nf_reject_ipv4, from Tahee Yoo.
9) Pass nft_ctx struct to object initialization indirections, from
Florian Westphal.
10) Add code to integrate conntrack helper into nf_tables, also from

11) Allow to check if interface index or name exists via
NFTA_FIB_F_PRESENT, from Phil Sutter.
12) Simplify resolve_normal_ct(), from Florian.
13) Use per-limit spinlock in nft_limit and xt_limit, from Liping Zhang.
14) Use rwlock in nft_set_rbtree set, also from Liping Zhang.
15) One patch to remove a useless printk at netns init path in ipvs,
and several patches to document IPVS knobs.
16) Use refcount_t for reference counter in the Netfilter/IPVS code,
from Elena Reshetova.

The DS4 motion sensors are currently mapped by the hid-core driver
to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because
the device already exhausted ABS_X-ABS_RZ. For a part the mapping
by hid-core is accomplished by a fixup in hid-sony as the motion
axes actually use vendor specific usage pages.
This patch makes the DS4 use a separate input device for the motion
sensors and reports acceleration data through ABS_X-ABS_Z and
gyroscope data through ABS_RX-ABS_RZ. In addition it extends the
event spec to allow gyroscope data through ABS_RX-ABS_RZ when
INPUT_PROP_ACCELEROMETER is set. This change was suggested by
Peter Hutterer during a discussion on linux-input.

The WM8903 has four different voltage inputs: AVDD, CPVDD, DBVDD
and DCVDD. On the Qualcomm APQ8060 Dragonboard these are all
supplied from proper regulators and thus need activating and
binding.
This is a quick-and-dirty solution just grabbing and enabling the
regulator supplies on probe() and disabling them on remove() and
the errorpath. More elaborate power management is likely possible.
I assume the nVidia designs using this codec have some hard-wired
always-on power and will be happy with using the dummy regulators
for this. But someone from the nVidia camp should probably check
whether they can bind these to proper regulators instead.
We also amend the DT binding document. A small change like this
does not warrant a separate patch for augmenting these.

initially proposed till patch V4 [1] but then discarded in V5 [2]

The above properties never landed in mainline code but were then
listed in the binding example by a following commit dc715452e9
("spi: pl022: use generic DMA slave configuration if possible")
and later on they were copy-paste in some board's DT.
