Fabio Estevam 493a86365b ARM: dts: imx51-babbage: Make DVI and WVGA panel functional
Currently we get the following errors on imx51-babbage:

/display@di0: could not find display-timings node
/display@di0: no timings specified
/display@di1: could not find display-timings node
/display@di1: no timings specified
imx-drm imx-drm: failed to allocate buffer with size 0

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.

Sascha Hauer dc071436dc ARM: dts: i.MX51 babbage: Add spi-cs-high property to pmic
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.

Shawn Guo e16415313c pinctrl: imx: move hard-coding data into device tree
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.

Shawn Guo 36dffd8f49 ARM: imx: use #include for all device trees
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.

Shawn Guo be4ccfcec3 ARM: dts: imx: use nodes label in board dts
Following omap3-evm.dts way, it changes all imx dts files to use label
in board dts to refer to nodes defined by soc dtsi.  Thus, the board
dts files become easier to read and edit with the least indentation
levels.
