In order to use the mctrl_gpio helpers, we change the DT bindings:
ri-gpios renamed to rng-gpios. cd-gpios renamed to dcd-gpios.
However, no in-tree dts/dtsi specifies these, so no worries.

This patch adds a new DT property, "atmel,fifo-size", to enable and set
the maximum number of data the RX and TX FIFOs can store on FIFO capable
USARTs.
Please be aware that the VERSION register can not be used to guess the
size of FIFOs. Indeed, for a given hardware version, the USARTs can be
integrated on Atmel SoCs with different FIFO sizes. Also the
"atmel,fifo-size" property is optional as older USARTs don't embed FIFO at
all.
Besides, the FIFO size can not be read or guessed from other registers:
When designing the FIFO feature, no dedicated registers were added to
store this size. Unsed spaces in the I/O register range are limited and
better reserved for future usages. Instead, the FIFO size of each
peripheral is documented in the programmer datasheet.
Finally, on a given SoC, there can be several instances of USART with
different FIFO sizes. This explain why we'd rather use a dedicated DT
property than use the "compatible" property.

Due to Advisory 21 as documented in AM437x errata document,
UART module cannot be disabled once DMA is used. The only
workaround is to softreset the module before disabling it.
DRA7x UARTs are compatible to AM437x UARTs in terms of
this errata and prescribed workaround.
Enable usage of workaround for this errata on DRA7x SoCs.

Use of of_machine_is_compatible() for handling AM335x specific
"DMA kick" quirk in 8250_omap driver makes it ugly to extend the
quirk for other platforms. Instead use a new compatible.
The new compatible will also make it easier to take care of
other quirks on AM335x and like SoCs.
In order to not break backward DTB compatibility for users of
8250_omap driver on AM335x based boards, existing use of
of_machine_is_compatible() has not been removed.

The ARM Server Base System Architecture[1] document describes a
generic UART which is a subset of the PL011 UART.
It lacks DMA support, baud rate control and modem status line
control, among other things.
The idea is to move the UART initialization and setup into the
firmware (which does this job today already) and let the kernel just
use the UART for sending and receiving characters.
We use the recent refactoring to build a new struct uart_ops
variable which points to some new functions avoiding access to the
missing registers. We reuse as much existing PL011 code as possible.
In contrast to the PL011 the SBSA UART does not define any AMBA or
PrimeCell relations, so we go with a pretty generic probe function
which only uses platform device functions.
A DT binding is provided with this patch, ACPI support is added in a
separate one.

As always, this tends to be one of our bigger branches. There are lots of
updates this release, but not that many jumps out as something that needs
more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- More graphics DT pieces falling into place on Exynos, bridges, clocks.
- Plenty of DT updates for Qualcomm platforms for various IP blocks
- Some churn on Tegra due to switch-over to tool-generated pinctrl data
- Misc fixes and updates for Atmel at91 platforms
- Various DT updates to add IP block support on Broadcom's Cygnus platforms
- More updates for Renesas platforms as DT support is added for various IP
blocks (IPMMU, display, audio, etc).

board file as suggested by Sekhar Nori <nsekhar@ti.com>. As it's
the last patch in the series, the last patch can be simply reverted
if needed.
As this series touches quite a bit of arch code, it was suggested
by Kalle Valo <kvalo@codeaurora.org> that the whole series should
be merged via the arm-soc tree.

This patchset attempts to standardize the naming of dt-bindings

the dt-bindings document the "vendor,binding.txt" style is in use by
some of the other vendors.

Merge tag 'v4.0-rc3' into HEAD
Linux 4.0-rc3
Merging in v4.0-rc3 because commit 30a22c215a (console: Fix
console name size mismatch) is a dependency.
Fixed behaviour of get_mctrl() serial driver function as documented in:
https://www.kernel.org/doc/Documentation/serial/driver
Added device-tree properties 'dcd-override', 'dsr-override',
'cts-override', and 'ri-override' specific to the Synopsis 8250
DesignWare UART driver. Allows one to force Data Carrier Detect,
Clear To Send, and Data Set Ready signals to permanently be reported as
active. The Ring indicator can be forced to be reported as inactive.
It is possible that if modem control signalling is enabled on a port
that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the
driver can hang indefinitely waiting for the state to change. The new
DT properties allow the driver to ignore the state of these pins on
serial ports that don't support them, as recommended in the kernel
documentation.

http://marc.info/?l=linux-tegra&m=142201349727836&w=2
DT binding text files have been updated for the following IP blocks:
- PCIe
- SOR
- SoC timers
- AHB "gizmo"
- APB_MISC
- pinmux control
- UART
- PWM
- I2C
- SPI
- RTC
- PMC
- eFuse
- AHCI
- HDA
- XUSB_PADCTRL
- SDHCI
- SOC_THERM
- AHUB
- I2S
- EHCI
- USB PHY
N.B. The nvidia,tegra20-timer compatible string is removed from the
nvidia,tegra30-timer.txt documentation file because it's already
mentioned in the nvidia,tegra20-timer.txt documentation file.
This second version takes into account the following requests from
Rob Herring <robherring2@gmail.com>:
- Per-IP block patches have been combined into a single patch
- Explicit documentation about which compatible strings are actually
matched by the driver has been removed. In its place is implicit
documentation that loosely follows Rob's prescribed format:
"Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where
<chip> is tegra30, tegra132, ..." [...] "You should attempt to
document known values of <chip> if you use it"

Make the map match the reality, the current binding text is
nonsense:
- The clock required for the clocking of the serial port
must come first and is not optional (as the driver will
otherwise proceed to grab and use the apb_pclk as uartclk),
and the apb_pclk that clocks the logic must come second
as the code will retrieve the first clock by index,
whereas the PrimeCell but will explicitly look for
"apb_pclk" so this can be specified later, as it is
looked up by name.
- The pin control state "default" is the only mandated
state, the sleep state is entirely optional.
We also add an example to avoid further confusion.

Dedicated CTS and RTS pins are unusable together with a lot of other
peripherals because they share the same line. Pinctrl is limited.
Moreover, the AUART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.
This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

Newer WonderMedia chips introduced another flag in the UART line control
register, which controls whether RTS/CTS signalling should be handled in
the driver or by the hardware itself.
This patch ensures that the kernel can control RTS/CTS (including
disabling it altogether) by forcing this flag to software mode on affected
chips (only WM8880 so far).
Also remove the redundant copy of the binding doc, while we are here.

This reverts commit 06aa82e498.
This commit purports to enable auto CTS flow control for the 8250
UART driver. However, the 8250 UART driver already supports auto
CTS flow control via UART_CAP_AFE and UART_CAP_EFR. Indeed, this
patch introduces another DT attribute for which an existing firmware
flag already exists ("auto-flow-control"). Furthermore, the use of
UPF_HARD_FLOW requires the UART driver to define .throttle and
.unthrottle methods, neither of which are defined for the 8250 UART
driver (which will result in a NULL ptr dereference). Finally, this patch
supposes to fix existing bugs in the serial core for auto CTS-enabled
hardware, but does not include the class of hardware for which these
bugs exist.

CLPS711X serial driver uses the system wide registers to control the
modem signals. Now gpio-syscon driver can be used for this purposes.
mctrl_gpio helpers allow us to create GPIO bindings for any of modem/tty

This patch makes such change.

Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new platforms,
but there's also a bit of cleanup and code removal for things that
are moved from platform code to DT contents (some OMAP clock code in
particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no particular
order:
* Rockchip RK3288 SoC support, including DTS for a dev board that they
have seeded with some community developers.
* Better support for Hardkernel Exynos4-based ODROID boards.
* CCF conversions (and dtsi contents) for several Renesas platforms.
* Gumstix Pepper (TI AM335x) board support
* TI eval board support for AM437x
* Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an Ippo

* Allwinner A31 Hummingbird board support, not to be confused with the

8250 uart driver currently supports only software assisted hw flow

flag in the tty structure to stop and start transmission and use modem
status interrupt for the event to drive the handshake signals. This is
not needed if hw has flow control capabilities. This patch adds a
DT attribute for enabling hw flow control for a uart port. Also skip
stop and start if this flag is present in flag field of the port
structure.

Updates of SoC-near drivers and other driver updates that makes more sense to
take through our tree.
The largest part of this is a conversion of device registration for some
renesas shmobile/sh devices over to use resources. This has required
coordination with the corresponding arch/sh changes, and we've agreed
to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure firmware,
which is what is used on many of the commercial Nvidia Tegra products
that are in the market, including the Nvidia Shield. The code is local
to arch/arm at this time since it's uncertain whether it will be shared
with arm64 longer-term, if needed we will refactor later.
A couple of new RTC drivers used on ARM boards, merged through our tree
on request by the RTC maintainer.
... plus a bunch of smaller updates across the board, gpio conversions
for davinci, etc.

This passes the errata fix using a GPIO to control the RTS pin
on one of the AT91 chips to use gpiolib instead of the
AT91-specific interfaces. Also remove the reliance on
compile-time #defines and the cpu_* check and rely on the
platform passing down the proper GPIO pin through platform
data.
This is a prerequisite for getting rid of the local GPIO
implementation in the AT91 platform and move toward
multiplatform.
The patch also adds device tree support for getting the
RTS GPIO pin from the device tree on DT boot paths.

Update all the Tegra DT bindings to require the standard dmas/dma-names
properties rather than non-standard nvidia,dma-request-selector property.
This is a DT-ABI-incompatible change. It is the second of two changes

being the previous conversion to the common reset bindings.

Update all the Tegra DT bindings to require resets/reset-names properties
where the HW module has reset inputs. Remove any entries from clocks or
clock-names that were only required to identify reset inputs, rather than
referring to real clocks.

Many of the Tegra DT binding documents say nothing about the clocks or
clock-names properties, yet those are present and required in DT files.
This patch simply updates the documentation file to match the implicit
definition of the binding, based on real-world DT content.
All Tegra bindings that mention clocks are updated to have consistent
wording and formatting of the clock-related properties.

Because most of the vendor prefixes are lower case, deprecate
the vendor prefix "ALTR" in place of "altr" for Altera Corp..

Let's fix up the msm serial device bindings so that it's clearer
what hardware is supported. Instead of using hsuart (for high
speed uart) let's use uartdm because that matches the actual name
of the hardware. Also, let's add the version information in case
we need to differentiate between different versions of the
hardware in the future. Finally, lets specify that clocks are
required (the clock bindings didn't exist when the original
binding was written) and also specify dma bindings just in case
we want to use it in software. We split the binding into two
files to make it clearer what's required and not required.
