Based on the Allwinner A64 user manual and on the previous sunxi
pinctrl drivers this introduces the pin multiplex assignments for
the ARMv8 Allwinner A64 SoC.
Port A is apparently used for the fixed function DRAM controller, so
the ports start at B here (the manual mentions "n from 1 to 7", so
not starting at 0).

ARM: OMAP2+: critical DRA7xx fix for v4.5-rc
Force the DRA7xx Ethernet internal clock source to stay enabled
per TI erratum i877:
http://www.ti.com/lit/er/sprz429h/sprz429h.pdf
Otherwise, if the Ethernet internal clock source is disabled, the
chip will age prematurely, and the RGMII I/O timing will soon
fail to meet the delay time and skew specifications for 1000Mbps
Ethernet.
This fix should go in as soon as possible.
Basic build, boot, and PM test results are available here:

In the add-on file for the GIC dealing with the RealView family
we currently only handle the PB11MPCore, let's extend this to
manage the RealView EB ARM11MPCore as well. The Revision B of the
ARM11MPCore core tile is a bit special and needs special handling
as it moves a system control register around at random.

This patch adds support for the mcp23s18 which is very similar to
the mcp23s17. A couple of control bits are not the same.
Notable IOCON_HAEN (s17 only) & IOCON_INTCC. Which can be ignored.
Patch changes the following:
- Add mcp23s18 types.
- Always set mirror bit if the dts defines mcp23s18. regardless of type.
Mirror bit is ignored on 8 bit devices anyway.
- In mcp23s08_probe use chip.ngpio instead of logic based on type
to determine number of gpio lins to increment by. This is set
appropiately by the call to mcp23s08_probe_one.
- Add mcp23s18 to device tree documentation.
- Remove statement that irqs don't work for spi. They do.
Tested with mcp23s18.

The altr,interrupt-trigger property is not used by the driver.
Instead, altr,interrupt-type is used by the driver and the driver
does not probe if this property is not specified. Therefore, it
is expected that there are no users of the -trigger property in
the wild and that this is a typo in the documentation for the
altera-pio controller. This patch fixes the typo.

Add device tree support for the I2C and SPI variant of AD7879(-1).
This allows to specify the touchscreen controller as a I2C client
node or SPI slave device. Most of the options available in platform
data are also available as device tree properties, the only exception
being GPIO capabilities, which can not be activated through device
tree currently.

Armada-3700's uart is a simple serial port, which doesn't
support. Configuring the modem control lines. The uart port has a 32
bytes Tx FIFO and a 64 bytes Rx FIFO
The uart driver implements the uart core operations. It also support the
system (early) console based on Armada-3700's serial port.
Known Issue:
The uart driver currently doesn't support clock programming, which means
the baud-rate stays with the default value configured by the bootloader
at boot time

ath.git patches for 4.6. Major changes:

* dt: add bindings for ipq4019 wifi block
* start adding support for qca4019 chip
ath9k
* add device ID for Toshiba WLM-20U2/GN-1080
* allow more than one interface on DFS channels
Although most of USB devices are hot-plug's, there are still some devices
are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
If these kinds of USB devices are multiple functions, and they can supply
other interfaces like i2c, gpios for other devices, we may need to
describe these at device tree.
In this commit, it uses "reg" in dts as physical port number to match
the phyiscal port number decided by USB core, if they are the same,
then the device node is for the device we are creating for USB core.
