The 'groups' parameter of hwmon_device_register_with_info() and
devm_hwmon_device_register_with_info() is only necessary if extra
non-standard attributes need to be provided. Rename the parameter
to extra_groups and clarify the documentation.

f4d325d5ed hwmon: (core) Clarify use of chip attributes
Describing chip attributes as "attributes which apply to the entire chip"
is confusing. Rephrase to "attributes which are not bound to a specific
input or output".

Also rename hwmon_chip_attr_templates[] to hwmon_chip_attrs[] to indicate
that the respective strings strings are not templates but actual attribute
names.

c538f6ec9f dm crypt: add ability to use keys from the kernel key retention service
The kernel key service is a generic way to store keys for the use of
other subsystems. Currently there is no way to use kernel keys in dm-crypt.
This patch aims to fix that. Instead of key userspace may pass a key
description with preceding ':'. So message that constructs encryption
mapping now looks like this:

  <cipher> [<key>|:<key_string>] <iv_offset> <dev_path> <start> [<#opt_params> <opt_params>]

where <key_string> is in format: <key_size>:<key_type>:<key_description>

Currently we only support two elementary key types: 'user' and 'logon'.
Keys may be loaded in dm-crypt either via <key_string> or using
classical method and pass the key in hex representation directly.

dm-crypt device initialised with a key passed in hex representation may be
replaced with key passed in key_string format and vice versa.

(Based on original work by Andrey Ryabinin)

4022d039a3 net: smmac: allow configuring lower pbl values
The driver currently always sets the PBLx8/PBLx4 bit, which means that
the pbl values configured via the pbl/txpbl/rxpbl DT properties are
always multiplied by 8/4 in the hardware.

In order to allow the DT to configure lower pbl values, while at the
same time not changing behavior of any existing device trees using the
pbl/txpbl/rxpbl settings, add a property to disable the multiplication
of the pbl by 8/4 in the hardware.

89caaa2d80 net: stmmac: add support for independent DMA pbl for tx/rx
GMAC and newer supports independent programmable burst lengths for
DMA tx/rx. Add new optional devicetree properties representing this.

To be backwards compatible, snps,pbl will still be valid, but
snps,txpbl/snps,rxpbl will override the value in snps,pbl if set.

If the IP is synthesized to use the AXI interface, there is a register
and a matching DT property inside the optional stmmac-axi-config DT node
for controlling burst lengths, named snps,blen.
However, using this register, it is not possible to control tx and rx
independently. Also, this register is not available if the IP was
synthesized with, e.g., the AHB interface.

snps,tso was previously placed under AXI BUS Mode parameters,
suggesting that the property should be in the stmmac-axi-config node.

TSO (TCP Segmentation Offloading) has nothing to do with AXI BUS Mode

not in the stmmac-axi-config.

====================
Netfilter/IPVS updates for net-next

The following patchset contains a large Netfilter update for net-next,
to summarise:

1) Add support for stateful objects. This series provides a nf_tables
   native alternative to the extended accounting infrastructure for
   nf_tables. Two initial stateful objects are supported: counters and
   quotas. Objects are identified by a user-defined name, you can fetch
   and reset them anytime. You can also use a maps to allow fast lookups
   using any arbitrary key combination. More info at:

   http://marc.info/?l=netfilter-devel&m=148029128323837&w=2

2) On-demand registration of nf_conntrack and defrag hooks per netns.
   Register nf_conntrack hooks if we have a stateful ruleset, ie.
   state-based filtering or NAT. The new nf_conntrack_default_on sysctl
   enables this from newly created netnamespaces. Default behaviour is not
   modified. Patches from Florian Westphal.

3) Allocate 4k chunks and then use these for x_tables counter allocation
   requests, this improves ruleset load time and also datapath ruleset
   evaluation, patches from Florian Westphal.

4) Add support for ebpf to the existing x_tables bpf extension.
   From Willem de Bruijn.

5) Update layer 4 checksum if any of the pseudoheader fields is updated.
   This provides a limited form of 1:1 stateless NAT that make sense in
   specific scenario, eg. load balancing.

6) Add support to flush sets in nf_tables. This series comes with a new
   set->ops->deactivate_one() indirection given that we have to walk
   over the list of set elements, then deactivate them one by one.
   The existing set->ops->deactivate() performs an element lookup that
   we don't need.

7) Two patches to avoid cloning packets, thus speed up packet forwarding
   via nft_fwd from ingress. From Florian Westphal.

8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to
   prevent infinite loops, patch from Dwip Banerjee. And one minor
   refactoring from Gao feng.

9) Revisit recent log support for nf_tables netdev families: One patch
   to ensure that we correctly handle non-ethernet packets. Another
   patch to add missing logger definition for netdev. Patches from
   Liping Zhang.

10) Three patches for nft_fib, one to address insufficient register
    initialization and another to solve incorrect (although harmless)
    byteswap operation. Moreover update xt_rpfilter and nft_fib to match
    lbcast packets with zeronet as source, eg. DHCP Discover packets
    (0.0.0.0 -> 255.255.255.255). Also from Liping Zhang.

11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from
    Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has
    been broken in many-cast mode for some little time, let's give them a
    chance by placing them at the same level as other existing protocols.
    Thus, users don't explicitly have to modprobe support for this and
    NAT rules work for them. Some people point to the lack of support in
    SOHO Linux-based routers that make deployment of new protocols harder.
    I guess other middleboxes outthere on the Internet are also to blame.
    Anyway, let's see if this has any impact in the midrun.

12) Skip software SCTP software checksum calculation if the NIC comes
    with SCTP checksum offload support. From Davide Caratti.

13) Initial core factoring to prepare conversion to hook array. Three
    patches from Aaron Conole.

14) Gao Feng made a wrong conversion to switch in the xt_multiport
    extension in a patch coming in the previous batch. Fix it in this
    batch.

15) Get vmalloc call in sync with kmalloc flags to avoid a warning
    and likely OOM killer intervention from x_tables. From Marcelo
    Ricardo Leitner.

16) Update Arturo Borrero's email address in all source code headers.

7087140d50 net: hix5hd2_gmac: add reset control and clock signals
Add three reset control signals, "mac_core_rst", "mac_ifc_rst" and
"phy_rst".
The following diagram explained how the reset signals work.

                                  ----------

The "mac_core_rst" represents "mac core reset signal", it resets
the mac core including packet processing unit, descriptor processing unit,
tx engine, rx engine, control unit.
The "mac_ifc_rst" represents "mac interface reset signal", it resets
the mac interface. The mac interface unit connects mac core and
data interface like MII/RMII/RGMII. After we set a new value of
interface mode, we must reset mac interface to reload the new mode value.
The "mac_core_rst" and "mac_ifc_rst" are both optional to be
backward compatible with the hix5hd2 SoC.
The "phy_rst" represents "phy reset signal", it does a hardware reset
on the PHY chip. This reset signal is optional if the PHY can work well
without the hardware reset.

Add one more clock signal, the existing is MAC core clock,
and the new one is MAC interface clock.
The MAC interface clock is optional to be backward compatible with
the hix5hd2 SoC.

Jon,

Did a patch fixing the quibbles.

As it seems you didn't push yet the changeset upstream, feel free to
just fold it with patch 5/5 if you prefer so, or to add as a separate
patch at the end of the series.

Patch enclosed.

Thanks,
Mauro

579c49efdf PM / OPP: Reword binding supporting multiple regulators per device
On certain platforms (like TI), DVFS for a single device (CPU) requires
configuring multiple power supplies.

The OPP bindings already contains binding and example to explain this
case, but it isn't sufficient.

- There is no way for the code parsing these bindings to know which
  voltage values belong to which power supply.

- It is not possible to know the order in which the supplies need to be
  configured while switching OPPs.

This patch clarifies on those details by mentioning that such
information is left for the implementation specific bindings to explain.
They may want to hardcode such details or implement their own properties
to get such information. All implementations using multiple regulators
for their devices must provide a binding document explaining their
implementation.

309fe8d650 PM / OPP: Fix incorrect cpu-supply property in binding
The regulator bindings allow the "<name>-supply" property to define a
single parent supply and not a list of parents.

Fix the wrong example code present in OPP bindings.

While at it also change the compatible string as Rob pointed out earlier
that none of A7 implementation have multiple supplies for the CPU core.
