791d3ef2e1 dt-bindings: remove 'interrupt-parent' from bindings
'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

9abf8acea2 TTY/Serial driver patches for 4.17-rc1
Here is the big set of tty and serial driver patches for 4.17-rc1
 
 Not all that big really, most are just small fixes and additions to
 existing drivers.  There's a bunch of work on the imx serial driver
 recently for some reason, and a new embedded serial driver added as
 well.
 
 Full details are in the shortlog.
 
 All of these have been in the linux-next tree for a while with no
 reported issues.

As a kernel newcomer, I got bitten by lack of examples on this front. I
had troubles figuring out where these clocks could be defined ("/clocks"
is where the generic infrastructure expects them).

One should also ensure that a unique name is used. Generic names such as
"osc" tend to be already used by some board-wide clock crystals.

    Disabling IRQ #51

On a multi-UART max310x, each UART has its own interrupt status register
which automatically de-asserts the IRQ line upon read. (There are also
top-level IRQ indicator registers which are not clear-on-read, but they
are not relevant here.) It was quite possible to receive a pending IRQ
for, e.g., UART0, enter the threaded IRQ handler, clear the ISR for
UART0 which de-asserts the IRQ line, and then race with another event on
the same chip, but a different UART channel. That resulted in another
edge on the shared-within-the-chip IRQ line which got intercepted by the
kernel.

That all led to an edge-level interrupt which was not being handled by
anybody because our threaded handler hasn't finished yet. As the chip

d160c34134 dt-bindings: mvebu-uart: update documentation with extended UART
Update the device tree binding documentation for the Marvell EBU UART,
in order to allow describing the extended UART IP block, in addition to
the already supported standard UART IP. This requires adding a new
compatible string, the introduction of a clocks property, and extensions
to the interrupts property.

6abe9ea8a5 dt-bindings: serial: Add common rs485 binding for RTS polarity
rs485 allows for robust half-duplex serial communication.  It is often
implemented by attaching an rs485 transceiver to a UART.  The UART's
RTS line is wired to the transceiver's Transmit Enable pin and
determines whether the transceiver is sending or receiving.

Examples for such transceivers are Maxim MAX13451E and TI SN65HVD1781A:
https://datasheets.maximintegrated.com/en/ds/MAX13450E-MAX13451E.pdf
http://www.ti.com/lit/ds/symlink/sn65hvd1781a-q1.pdf

In the devicetree, the transceiver itself is not represented, only the
UART is.  A few rs485-specific dt-bindings already exist and these go
into the UART's device node.

This commit adds a binding to set the RTS polarity.  Most (if not all)
transceivers require the Transmit Enable pin be driven high for sending,
but in some cases boards may negate the pin and RTS must then be driven
low.  Consequently the polarity defaults to active high but can be
inverted with the newly added "rs485-rts-active-low" binding.

Document this binding in rs485.txt and in the two drivers fsl-imx-uart
and fsl-lpuart that are about to be amended with support for it.

Curiously, the omap_serial driver defaults to active low and already
supports an "rs485-rts-active-high" binding to invert the polarity.
This is left unchanged to retain compatibility, but the binding is
herewith documented.

527d147074 ARM: Device-tree updates for 4.15
We add device tree files for a couple of additional SoCs in various areas:
 
 Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking,
 Amlogic A113D for audio, and Renesas R-Car V3M for automotive.
 
 As usual, lots of new boards get added based on those and other SoCs:
 
  - Actions S500 based CubieBoard6 single-board computer
 
  - Amlogic Meson-AXG A113D based development board
  - Amlogic S912 based Khadas VIM2 single-board computer
  - Amlogic S912 based Tronsmart Vega S96 set-top-box
 
  - Allwinner H5 based NanoPi NEO Plus2 single-board computer
  - Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers
  - Allwinner A83T based TBS A711 Tablet
 
  - Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8
  - Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500
      wireless access points and routers
 
  - NXP i.MX51 based Zodiac Inflight Innovations RDU1 board
  - NXP i.MX53 based GE Healthcare PPD biometric monitor
  - NXP i.MX6 based Pistachio single-board computer
  - NXP i.MX6 based Vining-2000 automotive diagnostic interface
  - NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants
 
  - Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone
  - Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet
 
  - Realtek RTD1295 based set-top-boxes MeLE V9 and PROBOX2 AVA
 
  - Renesas R-Car V3M (R8A77970) SoC and "Eagle" reference board
  - Renesas H3ULCB and M3ULCB "Kingfisher" extension infotainment boards
  - Renasas r8a7745 based iWave G22D-SODIMM SoM
 
  - Rockchip rk3288 based Amarula Vyasa single-board computer
 
  - Samsung Exynos5800 based Odroid HC1 single-board computer
 
 For existing SoC support, there was a lot of ongoing work, as usual
 most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic
 and Allwinner platforms, but others were also active.
 
 Rob Herring and many others worked on reducing the number of issues that
 the latest version of 'dtc' now warns about. Unfortunately there is still
 a lot left to do.
 
 A rework of the ARM foundation model introduced several new files
 for common variations of the model.

a449f12bfe dt-bindings: serial/rs485: make rs485-rts-delay optional
There are a few device trees that specify one of the already optional
properties without also having the up to now required property
rs485-rts-delay. Additionally there is no technical reason to require
rs485-rts-delay and that's also what most drivers implement.

So give existing users and implementers a blessing and document
rs485-rts-delay as optional.

a9ceea2674 ARM: 64-bit DT updates
Device-tree updates for arm64 platforms. For the first time I can
 remember, this is actually larger than the corresponding branch for
 32-bit platforms overall, though that has more individual changes.
 
 A significant portion this time is due to added machine support:
 
 - Initial support for the Realtek RTD1295 SoC, along with the Zidoo
   X9S set-top-box
 
 - Initial support for Actions Semi S900 and the Bubblegum-96
   single-board-cёmputer.
 
 - Rockchips support for the rk3399-Firefly single-board-computer
   gets added, this one stands out for being relatively fast,
   affordable and well₋supported, compared to many boards that
   only fall into one or two of the above categories.
 
 - Mediatek gains support for the mt6797 mobile-phone SoC platform
   and corresponding evaluation board.
 
 - Amlogic board support gets added for the NanoPi K2 and S905x
   LibreTech CC single-board computers and the R-Box Pro set-top-box
 
 - Allwinner board support gets added for the OrangePi Win,
   Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single
   board computers and the SoPine system-on-module.
 
 - Renesas board support for Salvator-XS and H3ULCB
   automotive development systems.
 
 - Socionext Uniphier board support for LD11-global and LD20-global,
   whatever those may be.
 
 - Broadcom adds support for the new Stingray communication processor
   in its iProc family, along with two reference boards.
 
 Other updates include:
 
 - For the hisicon platform, support for Hi3660-Hikey960 gets
   extended significantly.
 
 - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,
   Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP.

f2422fe437 dt-bindings: serial: fsl-lpuart: add i.MX7ULP support
The lpuart of imx7ulp is basically the same as ls1021a. It's also
32 bit width register, but unlike ls1021a, it's little endian.
Besides that, imx7ulp lpuart has a minor different register layout
from ls1021a.

a3015affdf serial: imx-serial - move DMA buffer configuration to DT
The size of the DMA buffer can affect the delta time between data being
produced and data being consumed. Basically the DMA system will move
data to tty buffer when a) DMA buffer is full b) serial line is idle.
The situation is visible when producer generates data continuously and
there is no possibility for idle line. At this point the DMA buffer is
directly affecting the delta time.

The patch will add the possibility to configure the DMA buffers in DT,
which case by case can be configured separately for every driver
instance. The DT configuration is optional and in case missing the
driver will use the 4096 buffer with 4 periods (as before), therefore no
clients are impacted by this change.
