The ASPEED SoC must deassert a reset in order to use the ADC peripheral.
The device tree bindings are updated to document the resets phandle, and
the example is updated to match what is expected for both the reset and
clock phandle. Note that the bindings should have always had the reset
controller, as the hardware is unusable without it.

The FlexCAN controller can be modelled as little or big endian depending
on SOC design. This device tree property identifies the controller
endianness and the driver reads/writes controller registers based on
that.
This is optional property. i.e. if this property is not present in
device tree node then controller is assumed to be little endian. if this
property is present then controller is assumed to be big endian.

With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver
is not always capable of avoiding the 25-35 ms timeout as specified by
the SMBUS protocol. This may cause silent corruption of the last bit of
any transfer, e.g. a one is read instead of a zero if the sensor chip
times out. This also affects the eeprom half of the nxp-se97 chip, where
this silent corruption was originally noticed. Other I2C adapters probably
suffer similar issues, e.g. bit-banging comes to mind as risky...
The SMBUS register in the nxp chip is not a standard Jedec register, but
it is not special to the nxp chips either, at least the atmel chips
have the same mechanism. Therefore, do not special case this on the
manufacturer, it is opt-in via the device property anyway.

The property used to specify a GPIO intended for reset is "reset-gpios",
but this binding uses "gpio-reset". It is not compatible with newer
methods used to fetch GPIO pins and to prevent the spread of this error
to other bindings let's rename to be more standard.
We also standardize the pin as active-low, different device trees have
marked the GPIO different ways, luckily the driver currently uses the
low-level GPIO set function which does not respect the active-low flag,
but future changes may change this. This is an active-low reset, mark
it as such.
Lastly, add an example of use for this property.

The driver makes the crosstalk funciton disabled by default

We change the property "nuvoton,crosstalk-bypass" to
"nuvoton,crosstalk-enable". The crosstalk measurement is enabled
if the property is set. Otherwise, it is disabled. Besides,
add more condition in the entry point of the crosstalk sequence

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.pdfhttp://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.

Pull clk updates from Stephen Boyd:
"We have two changes to the core framework this time around.
The first being a large change that introduces runtime PM support to
the clk framework. Now we properly call runtime PM operations on the
device providing a clk when the clk is in use. This helps on SoCs
where the clks provided by a device need something to be powered on
before using the clks, like power domains or regulators. It also helps
power those things down when clks aren't in use.
The other core change is a devm API addition for clk providers so we
can get rid of a bunch of clk driver remove functions that are just
doing of_clk_del_provider().
Outside of the core, we have the usual addition of clk drivers and
smattering of non-critical fixes to existing drivers. The biggest diff
is support for Mediatek MT2712 and MT7622 SoCs, but those patches
really just add a bunch of data.
By the way, we're trying something new here where we build the tree up
with topic branches. We plan to work this into our workflow so that we
don't step on each other's toes, and so the fixes branch can be merged
on an as-needed basis.
Summary:
Core:
- runtime PM support for clk providers
- devm API for of_clk_add_hw_provider()
New Drivers:
- Mediatek MT2712 and MT7622

Pull ARM SoC driver updates from Arnd Bergmann:
"This branch contains platform-related driver updates for ARM and
ARM64, these are the areas that bring the changes:
New drivers:
- driver support for Renesas R-Car V3M (R8A77970)
- power management support for Amlogic GX
- a new driver for the Tegra BPMP thermal sensor
- a new bus driver for Technologic Systems NBUS
Changes for subsystems that prefer to merge through arm-soc:
- the usual updates for reset controller drivers from Philipp Zabel,
with five added drivers for SoCs in the arc, meson, socfpa,
uniphier and mediatek families
- updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,
Heiner Kallweit and Lorenzo Pieralisi
Changes specific to some ARM-based SoC
- the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on
ARM as well
- several changes for power management on Broadcom SoCs
- various improvements on Qualcomm, Broadcom, Amlogic, Atmel,
Mediatek
- minor Cleanups for Samsung, TI OMAP SoCs"
[ NOTE! This doesn't work without the previous ARM SoC device-tree pull,
because the R8A77970 driver is missing a header file that came from
that pull.
The fact that this got merged afterwards only fixes it at this point,
and bisection of that driver will fail if/when you walk into the
history of that driver. - Linus ]
