Since commit b36581df7e78 ("spi: imx: Using existing properties for
chipselects") the device tree property 'fsl,spi-num-chipselects' is
unused and it is already marked as obsolete in device tree binding
documentation. Remove the property from the existing DTS files to
avoid its reoccurence on copying.

As of commit 1006ed7e1b258dac ("serial: imx: Use generic uart-has-rtscts
DT property"), the Freescale IMX UART driver recognizes the generic
"uart-has-rtscts" DT property, deprecating the vendor-specific
"fsl,uart-has-rtscts" DT property. Hence replace the latter by the
former in all DTS files.

Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux,wakeup" and "enable-sdio-wakeup" boolean
property to enable the wakeup source, "wakeup-source" is the new
standard binding.
This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

GPIO2_5 is the reset GPIO for the USB3317 ULPI PHY. Instead of modelling it as
a regulator, the correct approach is to use the 'reset_gpios' property of the
"usb-nop-xceiv" node.
GPIO1_7 is the reset GPIO for the USB2517 USB hub. As we currently don't have
dt bindings to describe a HUB reset, let's keep using the regulator approach.
Rename the regulator to 'reg_hub_reset' to better describe its function and bind
it with the USB host1 port instead.
USB host support has been introduced by commit 9bf206a9d13be3 ("ARM: dts:
imx51-babbage: Add USB Host1 support"), which landed in 3.16 and it seems that
USB has only been functional due to previous bootloader initialization.
With this patch applied we can get USB host to work without relying on the
bootloader.

The DAI mode is and should be configured by the sound card driver as
codec and ssi have to be in the right modes to communicate with each
other. It is possible to operate the ssi unit or the codec in master mode,
sometimes even on the same board in different configurations.
With the latest changes in the fsl-ssi driver, the 'fsl,mode' property
is only handled as a fallback property. If the sound card sets the DAI
mode correctly, this fallback configuration is dropped.

supported anymore by esdhc driver. Let's use GPIO for CD/WP on esdhc1

While at it, fix cd gpio polarity for esdhc2. This is wrong and

The dts relied on the FEC pad ctrl settings from the bootloader by
using the NO_PAD_CTRL option. This breaks once the bootloader starts

Pull ARM SoC device tree changes from Arnd Bergmann:
"A large part of the arm-soc patches are nowadays DT changes, adding
support for new SoCs, boards and devices without changing kernel
source. The plan is still to move the devicetree files out of the
kernel tree and reduce the amount of churn going on here, but we keep
finding reasons to delay doing that.
Changes are really all over the place, with little sticking out
particularly. We have contributions from a total of 116 people in
this branch.
Unfortunately, the size of this branch also causes a significant
number of conflicts at the moment, typically when subsystem
maintainers merge patches that change the driver at the same time as
the dts files. In most cases this could be avoided because the dts
changes are supposed to be compatible in both ways, and we are asking
everyone to send ARM dts changes through our tree only"

This patch connects IPU and and parallel display device tree
nodes using the OF graph bindings described in
Documentation/devicetree/bindings/media/video-interfaces.txt
The IPU ports correspond to the two display interfaces. The
order of endpoints in the ports is arbitrary.
Since the imx-drm node now only needs to contain links to the
display interfaces, it can be moved to the SoC dtsi level. At
the board level, only connections between the display interface
ports and panels have to be added.

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts. However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected. This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board. It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.
The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral. Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.

The mc13892 driver knows that it needs spi-cs-high, so the mc13892
will work. The dataflash also connected to this bus though can only
be probed when the mc13892 is inactive. Due to driver potential
differences in the probe order we can only make sure the mc13892
is inactive when we put the information into the devicetree.

Currently, all imx pinctrl drivers maintain a big array of struct
imx_pin_reg which hard-codes data like register offset and mux mode
setting for each pin function. Every time a new imx SoC support is
added, we need to add such a big mount of data. With moving to single
kernel build, it's only matter of time to be blamed on memory consuming.
With DTC pre-processor support in place, the patch moves all these data
into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and
changing the PIN_FUNC_ID parsing code a little bit.
The pin id gets re-numbered based on mux register offset, or config
register offset if the pin has no mux register, so that kernel can
identify the pin id from register offsets provided by device tree.
As a bonus point of the change, those arbitrary magic numbers standing
for particular PIN_FUNC_ID in device tree sources are now replaced by
macros to improve the readability of dts files.

Replace /include/ (dtc) with #include (C pre-processor) for all imx DT
files, so that gcc -E handles the entire include tree, and hence any of
those files can #include some other file e.g. for constant definitions.
This allows future use of #defines and header files in order to define
names for various constants, such as pinctrl settings. Use of those
features will increase the readability of the device tree files.
