It turns out that there are only 2 in-tree platforms which use MPICs
which are not "primary":  IBM Cell and PowerMac.  To reduce the
complexity of the typical board setup code, invert the MPIC_PRIMARY bit
into MPIC_SECONDARY.

Almost all PowerPC platforms use a standard "open-pic" device node so
the mpic_alloc() function now accepts NULL for the device-node.  This
will cause it to perform a default search with of_find_matching_node().

Instead of using the open-coded "reg" property lookup and address
translation in mpic_alloc(), directly call of_address_to_resource().
This includes various workarounds for special cases which the naive
of_address_translate() does not.

Afterwards it is possible to remove the copiously copy-pasted calls to
of_address_translate() from the 85xx/86xx/powermac platforms.

85xx board files have a lot of duplication in *_publish_devices()/

Standarize and document the FPGA nodes used on Freescale QorIQ reference
boards.  There are different kinds of FPGAs used on the boards, but
only two are currently standard: "pixis", "ngpixis", and "qixis".  Although
there are minor differences among the boards that have one kind of FPGA, most
of the functionality is the same, so it makes sense to create common
compatibility strings.

We also need to update the P1022DS platform file, because the compatible
string for its PIXIS node has changed.  This means that older kernels are
not compatible with newer device trees.  This is not a real problem, however,
since that particular function doesn't work anyway.  When the DIU is active,
the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped
device.

Instead of using ill-defined numbers (0, 1, and 2) for the monitor port, allow
the user to specify the port by name ("dvi", "lvds", or "dlvds").  This works
on the kernel command line, the module command-line, and the sysfs "monitor"
device.

Note that changing the monitor port does not currently work on the P1022DS,
because the code that talks to the PIXIS FPGA is broken.

To ensure that the DIU pixel clock will not be set to an invalid value,
clamp the PXCLK divider to the allowed range (2-255).  This also acts as
a limiter for the pixel clock.

The Freescale P1022DS has an on-chip video controller called the DIU, and a
driver for this device already exists.  Update the platform file for the
P1022DS reference board to enable the driver, and update the defconfig for
Freescale MPC85xx boards to add the driver.

Like the MPC8610 HPCD, the P1022DS ASoC DMA driver probes on individual DMA
channel nodes, so the DMA controller nodes' compatible string must be
listed in p1022_ds_ids[] to work.

Introduce basic support for the Freescale P1022DS reference board, based on the
Freescale BSP for this board.  This patch excludes the DIU, SSI, and MMC/SD
drivers.  Only a 36-bit DTS is provided.

Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS.
This means enabling 64-bit physical address support, increasing the maximum
zone order to 12 (to allow the DIU driver to allocate large chunks), and
clean up the audio options to disable the deprecated OSS support.
