This change adds a driver for the 16550-based Aspeed virtual UART
device. We use a similar process to the of_serial driver for device
probe, but expose some VUART-specific functions through sysfs too.
The VUART is two UART 'front ends' connected by their FIFO (no actual
serial line in between). One is on the BMC side (management controller)
and one is on the host CPU side.
This driver is for the BMC side. The sysfs files allow the BMC
userspace, which owns the system configuration policy, to specify at
what IO port and interrupt number the host side will appear to the host
on the Host <-> BMC LPC bus. It could be different on a different system
(though most of them use 3f8/4).
OpenPOWER host firmware doesn't like it when the host-side of the
VUART's FIFO is not drained. This driver only disables host TX discard
mode when the port is in use. We set the VUART enabled bit when we bind
to the device, and clear it on unbind.
We don't want to do this on open/release, as the host may be using this
bit to configure serial output modes, which is independent of whether
the devices has been opened by BMC userspace.

Merge tag 'devicetree-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Rewrite of the unflattening code to avoid recursion and lessen the
stack usage.
- Rewrite of the phandle args parsing code to get rid of the fixed args
size. This is needed for IOMMU code.
- Sync to latest dtc which adds more dts style checking. These
warnings are enabled with "W=1" compiles.
- Tegra documentation updates related to the above warnings.
- A bunch of spelling and other doc fixes.
- Various vendor prefix additions.

Document a set of generic properties for describing UARTs in a
device tree:
1. The GPIO modem control properties are currently duplicated across
hardware-specific binding documentation,
2. The property for dedicated RTS/CTS hardware flow control lines is
already supported by several drivers, albeit with a vendor-specific
prefix, hence make it generic.

As usual, the bulk of this release is again DT file contents.
There's a huge number of changes here, and it's challenging to give a crisp
overview of just what is in here. To start with:
New boards:
- TI-based DM3730 from LogicPD (Torpedo)
- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
- Raspberry Pi 2 DT files
- Watchdog on Meson8b
- Veyron-mickey (ASUS Chromebit) DTS
- Rockchip rk3228 SoC and eval board
- Sigma Designs Tango4
Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes.

As no platform defines an interface clock the SCI driver always falls
back to a clock named "peripheral_clk".
- On SH platforms that clock is the base clock for the SCI functional
clock and has the same frequency,
- On ARM platforms that clock doesn't exist, and clk_get() will return
the default clock for the device.
We can thus make the functional clock mandatory and drop the interface
clock.
EPROBE_DEFER is handled for clocks that may be referenced from DT (i.e.
"fck", and the deprecated "sci_ick").

If the DW_apb_uart is configured with UART_16550_COMPATIBLE
configuration parameter set, then the Busy Functionality is
not available. These UARTs will never generate the Busy
detect indication interrupt, and therefore don't need
handling for it.
This creates a small optimization for the DW_apb_uarts
configured without the busy functionality, but more
importantly, it removes the small but real risk of hitting
potential issues caused by busy functionality handling when
no busy functionality exist.

Here's our branch of ARM64 contents for this merge window.
Most of this is DT contents for new SoCs (or those who have seen new
device support added). Maybe we should stop separating out the arm64
contents here to avoid the kind of internal conflicts as we got this
time around, where 32- and 64-bit contents conflicted.
Anyhow, on the actual contents:
New SoCs:
- Broadcom North Star 2 (ns2)
- Marvell Berlin4CT
- Mediatek MT6795
- Rockchip RK3368
In addition, there are enhancements for the following platforms:
- Mediatek MT8173: cpuidle-dt updates, misc other additions
- ZyncMP: A bunch of devices added to the existing DTSI
- Qualcomm MSM8916 and APQ8016 updates for USB, etc.

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.

The new compatible will also make it easier to take care of
other quirks on AM335x and like SoCs.

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.

The mtk 8250 needs two clocks, one for providing the baudrate and
one that needs to be enabled for register accesses. The latter has
not been supported, this patch adds support for it. It is optional
for now since not all SoCs provide a bus clock.

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).

- Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom

The omap_serial.txt binding documentation lacks a number of properties
that are used in DTS files for platforms incorporating this peripheral.
Fix this by documenting the missing required and optional fields and
add an example.

The DBGU is not a simple UART and we need to be able to distinguish it from the
other UARTs, in particular to get its address and check the chip id.

The file of-serial.txt was only for 8250 compatible UART implementations,
so renamed it to 8250.txt to avoid confusing other persons.
This is suggested by Arnd, see:

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.

The 64-bit set of updates this release cycle adds support for three new platforms:
- Samsunc Exynos 7
- Freescale LS2085a
- Mediatek MT8173
For all these, the changes mostly consititude additions of DT contents,
but also some Kconfig entries to allow dependency/selection of drivers
per-platform, etc.

DT changes continue to be the bulk of our merge window contents.
We continue to have a large set of changes across the board as new platforms
and drivers are added.
Some of the new platforms are:
- Alphascale ASM9260
- Marvell Armada 388
- CSR Atlas7
- TI Davinci DM816x
- Hisilicon HiP01
- ST STiH418
There have also been some sweeping changes, including relicensing of DTS
contents from GPL to GPLv2+/X11 so that the same files can be reused in
other non-GPL projects more easily. There's also been changes to the
DT Makefile to make it a little less conflict-ridden and churny down
the road.
