e82b5fe5d4 dt-bindings: net: dsa: lantiq, xrx200-gswip: Fix minor style fixes
* Use one compatible line per line in the documentation
* Remove SoC revision depended compatible lines, we can detect that in
  the driver
* Use lower case letters in hex addresses
* Fix the size of the address ranges in the example, this now matches
  the sizes used by the SoC. The old ones will also work, this just adds
  some empty address space.
* Change the reg size of the gphy-fw node

d52030e6d5 dt-bindings: net: lantiq, xrx200-net: Use lower case in hex
Use lower case letters in the addresses of the device tree binding.
In addition replace eth with ethernet and fix the size of the reg
element in the example. The additional range does not contain any
registers but is used for the IP block on the this SoC.

86ce2bc73c dt-bindings: net: dsa: Add lantiq, xrx200-gswip DT bindings
This adds the binding for the GSWIP (Gigabit switch) core found in the
xrx200 / VR9 Lantiq / Intel SoC.

This part takes care of the switch, MDIO bus, and loading the FW into
the embedded GPHYs.

10d7fac4c5 dt-bindings: net: cpsw: Document cpsw-phy-sel usage but prefer phandle
The current cpsw usage for cpsw-phy-sel is undocumented but is used for
all the boards using cpsw. And cpsw-phy-sel is not really a child of
the cpsw device, it lives in the system control module instead.

Let's document the existing usage, and improve it a bit where we prefer
to use a phandle instead of a child device for it. That way we can
properly describe the hardware in dts files for things like genpd.

Meelis Roos reported a {menu,n}config regression:
 "I have libncurses devel package installed in the default system
  location (as do 99%+ on actual developers probably) and in this
  case, pkg-config is useless.  pkg-config is needed only when
  libraries and headers are installed in non-default locations but
  it is bad to require installation of pkg-config on all the machines
  where make menuconfig would be possibly run."

For {menu,n}config, do not use pkg-config if it is not installed.
For {g,x}config, keep checking pkg-config since we really rely on it
for finding the installation paths of the required packages.

82fe39a6bc i2c: refactor function to release a DMA safe buffer
a) rename to 'put' instead of 'release' to match 'get' when obtaining
   the buffer
b) change the argument order to have the buffer as first argument
c) add a new argument telling the function if the message was
   transferred. This allows the function to be used also in cases
   where setting up DMA failed, so the buffer needs to be freed without
   syncing to the message buffer.

Also convert the only user.

9b30049535 ethtool: drop get_settings and set_settings callbacks
Since [gs]et_settings ethtool_ops callbacks have been deprecated in
February 2016, all in tree NIC drivers have been converted to provide
[gs]et_link_ksettings() and out of tree drivers have had enough time to do
the same.

Drop get_settings() and set_settings() and implement both ETHTOOL_[GS]SET
and ETHTOOL_[GS]LINKSETTINGS only using [gs]et_link_ksettings().

973e5405f2 xen/blkback: don't keep persistent grants too long
Persistent grants are allocated until a threshold per ring is being
reached. Those grants won't be freed until the ring is being destroyed
meaning there will be resources kept busy which might no longer be
used.

Instead of freeing only persistent grants until the threshold is
reached add a timestamp and remove all persistent grants not having
been in use for a minute.

Merge tag 'iommu-updates-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU updates from Joerg Roedel:

 - PASID table handling updates for the Intel VT-d driver. It implements
   a global PASID space now so that applications usings multiple devices
   will just have one PASID.

 - A new config option to make iommu passthroug mode the default.

 - New sysfs attribute for iommu groups to export the type of the
   default domain.

 - A debugfs interface (for debug only) usable by IOMMU drivers to
   export internals to user-space.

 - R-Car Gen3 SoCs support for the ipmmu-vmsa driver

 - The ARM-SMMU now aborts transactions from unknown devices and devices
   not attached to any domain.

 - Various cleanups and smaller fixes all over the place.

 - Add Daniel Lezcano as the reviewer of thermal framework and SoC
   driver changes (Daniel Lezcano).

 - Fix a bug in intel_dts_soc_thermal driver, which does not translate
   IO-APIC GSI (Global System Interrupt) into Linux irq number (Hans de

e9880240e4 arm64: dts: Fix various entry-method properties to reflect documentation
The idle-states binding documentation[1] mentions that the
'entry-method' property is required on 64-bit platforms and must be
set to "psci".

commit a13f18f59d ("Documentation: arm: Fix typo in the idle-states
bindings examples") attempted to fix this earlier but clearly more is
needed.

Fix the cpu-capacity.txt documentation that uses the incorrect value so
we don't get copy-paste errors like these. Clarify the language in
idle-states.txt by removing the reference to the psci bindings that
might be causing this confusion.

Finally, fix devicetrees of various boards to reflect current
documentation.

idle-states node)

3723c63247 treewide: convert ISO_8859-1 text comments to utf-8
Almost all files in the kernel are either plain text or UTF-8 encoded.  A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.

This converts them all to UTF-8 for consistency.
