9734a7009d dt-bindings: display: renesas: lvds: Add EXTAL and DU_DOTCLKIN clocks
On the D3 and E3 SoCs, the LVDS encoder can derive its internal pixel
clock from an externally supplied clock, either through the EXTAL pin or
through one of the DU_DOTCLKINx pins. Add corresponding clocks to the DT
bindings.

To retain backward compatibility with DT that don't specify the
clock-names property, the functional clock must always be specified
first, and the clock-names property is optional when only the functional
clock is specified.

Merge tag 'du-next-20180914' of git://linuxtv.org/pinchartl/media into drm-next

R-Car DU changes for v4.20

The pull request mostly contains updates to the R-Car DU driver, notably
support for interlaced modes on Gen3 hardware, support for the LVDS output on
R8A77980, and a set of miscellaneous bug fixes. There are also two SPDX
conversion patches for the drm shmobile and panel-lvds drivers, as well as an
update to MAINTAINERS to add Kieran Bingham as a co-maintainer for the DU
driver.

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.

dt-bindings: riscv,cpu-intc: Cleanups from a missed review
I managed to miss one of Rob's code reviews on the mailing list
<http://lists.infradead.org/pipermail/linux-riscv/2018-August/001139.html>.
The patch has already been merged, so I'm submitting a fixup.

Sorry!

2e7c04aec8 dt-bindings: display: atmel: optional video-interface of endpoints
With bus-type/bus-width properties in the endpoint nodes, the video-
interface of the connection can be specified for cases where the
heuristic fails to select the correct output mode. This can happen
e.g. if not all RGB pins are routed on the PCB; the driver has no
way of knowing this, and needs to be told explicitly.

This is critical for the devices that have the "conflicting output
formats" issue (SAM9N12, SAM9X5, SAMA5D3), since the most significant
RGB bits move around depending on the selected output mode. For
devices that do not have the "conflicting output formats" issue
(SAMA5D2, SAMA5D4), this is completely irrelevant.

b326272010 ARM: SoC: late updates
A couple of late-merged changes that would be useful to get in this
 merge window:
 
  - Driver support for reset of audio complex on Meson platforms. The
    audio driver went in this merge window, and these changes have been
    in -next for a while (just not in our tree).
 
  - Power management fixes for IOMMU on Rockchip platforms, getting
    closer to kexec working on them, including Chromebooks.
 
  - Another pass updating "arm,psci" -> "psci" for some properties that
    have snuck in since last time it was done.

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.

  - Marvell Armada388-based Helios4 board from SolidRun
  - Samsung Aires-based phones (s5pv210)

9d2ab99573 ata: libahci_platform: add reset control support
Add support to get and control a list of resets for the device
as optional and shared. These resets must be kept de-asserted until
the device is enabled.

This is specified as shared because some SoCs like UniPhier series
have common reset controls with all ahci controller instances.

However, according to Thierry's view,
https://www.spinics.net/lists/linux-ide/msg55357.html
some hardware-specific drivers already use their own resets,
and the common reset make a path to occur double controls of resets.

The ahci_platform_get_resources() can get and control the reset
only when the second argument includes AHCI_PLATFORM_GET_RESETS bit.

Pull i2c updates from Wolfram Sang:

 - the core has now a lockless variant of i2c_smbus_xfer. Some open
   coded versions of this got removed in drivers. This also enables
   proper SCCB support in regmap.

 - locking got a more precise naming. i2c_{un}lock_adapter() had to go,
   and we know use i2c_lock_bus() consistently with flags like
   I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity.

 - the gpio fault injector got a new delicate testcase

 - the bus recovery procedure got fixed to handle the new testcase
   correctly

 - a new quirk flag for controllers not able to handle zero length
   messages together with driver updates to use it

 - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl
   family S900

 - and a good set of driver improvements and bugfixes
