Merge branch 'sh-pfc-for-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into devel

Common MVEBU pinctrl driver core gets an array of controls to modify
a specific set of registers and an array of modes for each pingroup
from each of the different SoC families of MVEBU.

Some SoC families comprise different variants that differ in available
pingroups and also controls, but to ease driver development, we can
pass a variant mask to disable specific pingroups for some variants.
However, controls are limited to the true number of pinctrl groups
avaiable on a variant.

Now, when pinctrl core driver parses over above arrays, it tries to
match modes with available controls and complains about missing
controls for modes that are passed to the core but actually are not
avaiable on a variant with:

kirkwood-pinctrl f1010000.pin-controller: unknown pinctrl group 36

This warning is a false-positive and annoying, so move the warning
after we checked the variant mask for each mode setting. Also, if
there is no supported setting for this variant, do not complain at
all.

Pins that (1) can be configured as either GPIO or a single peripheral
function, and (2) that don't need configuration in an IPSRx register,
should still be listed in the pinmux_data[] array.

Else selecting the peripheral function fails with e.g.:

    sh-pfc e6060000.pfc: cannot locate data/mark enum_id for mark 1281

(mark 1281 is MSIOF0_SCK_MARK).

The number of interrupts is always equal to the number of pins
provided by the PMIC gpio and MPP hardware blocks. Count the
number of irqs to figure out the number of pins instead of adding
more compatible strings or doing math on the reg property. This
should make the code more generic and ease the number of changes
we have to make to the driver for each new pmic revision.

"xrx300" and marks the "lantiq,pinctrl-xway", "lantiq,pinctrl-ase" and
"lantiq,pinctrl-xr9" bindings as DEPRECATED.

Based on the newest Lantiq Hardware Description it turend out, that there are
some differences in the GPIO alternative functions of the Danube, xRX100 and
xRX200 families, which makes it impossible to use only one xway_mfp table.

This patch also adds support for the xRX300 family.

resource_size_t may be defined as 32 or 64 bit depending on configuration,
so it cannot be printed using the normal format strings, as gcc correctly
warns:

pinctrl-at91-pio4.c: In function 'atmel_pinctrl_probe':
pinctrl-at91-pio4.c:1003:41: warning: format '%u' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=]
   dev_dbg(dev, "bank %i: hwirq=%u\n", i, res->start);

This changes the format string to use the special "%pr" format
string that prints a resource, and changes the arguments so we
