Since commit 89d7e5c1 (mmc: sdhci-esdhc-imx: add runtime pm
support), controller based card detection / write protection is not
supported anymore by esdhc driver.  Let's use GPIO for CD/WP on esdhc1
instead.

While at it, fix cd gpio polarity for esdhc2. This is wrong and
currently only works because the imx esdhc driver ignores the polarity.

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
initializing the pad ctrl settings from the same dts file. Change
to real pad ctrl settings taken from the platform based babbage

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.

/display@di0: no timings specified
/display@di1: could not find display-timings node
/display@di1: no timings specified

Provide timing values for IPU1, which is connected to a DVI bridge and
to IPU2, which can be connected to the WVGA panel, so that both of them can
be functional.

While at it, disable the WVGA panel, so that DVI output becomes the default one.

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

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.
