Commit d50f4630 ("arm: dts: Remove p1010-flexcan compatible from imx
series dts") removed the fallback compatible "fsl,p1010-flexcan" from
the imx device trees. As the flexcan cores on i.MX25, i.MX35 and i.MX53
are identical, introduce the first as fallback for the two latter ones.

Move pmu, usbphy0 and usbphy1 nodes from soc node to root node.

The nodes that have been moved do not have any register properties and thus
shouldn't be placed on the bus.

This fixes the following build warnings with W=1:

The flexcan driver has been modified to check for big-endian dts
property for be read/write to flexcan registers/mb.

An exception to this rule is powerpc P1010RDB, which is always
big-endian, even if big-endian is not present in dts. This is
checked using p1010-flexcan compatible in dts.

Therefore, remove p1010-flexcan compatible from imx series dts,
as their flexcan core is little endian.

Commit 7f107887 ("ARM: dts: imx: Remove skeleton.dtsi") causes boot
issues when the bootloader does not create a 'chosen' node if such node
is not present in the dtb.

The reason for the boot failure is well explained by Javier Martinez
Canillas: "the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info."

, so pass an empty 'chosen' node to fix the boot problem.

This issue has been seen in the kernelci reports with Barebox as
bootloader.

Also pass the 'memory' node in order to fix boot issues on the SolidRun
iMX6 platforms.

using LVDS channel 1 on an i.MX53 leads to following error:

imx-ldb 53fa8008.ldb: unable to set di0 parent clock to ldb_di1

This comes from imx_ldb_set_clock with mux = 0. Mux parameter must be "1" for
reparenting di1 clock to ldb_di1. The value of the mux param comes from device
tree port settings.

On i.MX5, the internal two-input-multiplexer is used. Due to hardware limitations,
only one port (port@[0,1]) can be used for each channel (lvds-channel@[0,1],
respectively)

This patch connects IPU and display encoder (VGA, LVDS)
device tree nodes, as well as parallel displays on the DISP0
and DISP1 outputs, 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 encoders or panels have to be added.
