Based on the Allwinner A64 user manual and on the previous sunxi
pinctrl drivers this introduces the pin multiplex assignments for
the ARMv8 Allwinner A64 SoC.
Port A is apparently used for the fixed function DRAM controller, so
the ports start at B here (the manual mentions "n from 1 to 7", so
not starting at 0).

In the Amlogic Meson8 / Meson8b platforms we have two different buses:
cbus and aobus, corresponding to 2 different power domains (regular and
always-on). On each bus a different set of registers is mapped to manage
muxes, GPIOs and in general to control a clear subset of the pins.

Considering this architecture, having two different pinctrl devices, one
for each bus / power domain, makes much more sense than just having one
single device.

Right now we have one single pin controller driver that uses two
different domains (represented by 'gpio' and 'gpio-ao' sub-nodes in the
DTS) to manage the set of registers on the two buses. This dual-domain
configuration is hardcoded into the driver that strictly requires one
domain for each bus in the same pin controller device.

With this patch we refactor the driver to allow splitting the driver in
two parts. This change is needed to have a proper description of the HW
in the device-tree where we want to introduce aobus and cbus.

The at91-pio4 pinctrl driver uses SET_SYSTEM_SLEEP_PM_OPS() to
conditionally set the correct suspend/resume options, but they
become unused when CONFIG_PM is disabled:

drivers/pinctrl/pinctrl-at91-pio4.c:827:12: error: 'atmel_pctrl_suspend' defined but not used [-Werror=unused-function]
drivers/pinctrl/pinctrl-at91-pio4.c:847:12: error: 'atmel_pctrl_resume' defined but not used [-Werror=unused-function]

This adds __maybe_unused annotations so the compiler knows
it can silently drop them instead of warning.

While I was testing irq's on the cubietruck I found a couple of
not working irq pins. Further diving into the problem it opened
up a mess called "manual".

This so called manual (A20 user manual v1.3 dated 2014-10-10) says:

Pin overview:
    Page 237:       EINT26 is on mux 5.
    Page 288:       EINT26 is on mux 6.

The manual is so contradicting that further tests had to be made
to see which of the 2 statements where correct.

This patch is based on actual outcome of these tests and not what
the manual says.

Test procedure used:

Connect a 1 pulse per second (GPS) line to the pin.

echo pin### > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio###/direction
echo rising > /sys/class/gpio/gpio###/edge

Check /proc/interrupts if a irq was attached and if irq's where
received.

which don't work without a device. This patch associates the syscon regmap
that handles the IOMUX controller's general purpose registers with the
pinctrl device so that the GPR registers appear in the regmap debugfs
directory again. For example, on i.MX6Q the GPR registers now can be
read from /sys/kernel/debug/regmap/20e0000.iomuxc-gpr/registers.

Add support for setting up GPIO pin interrupts in the lpc18xx pinctrl
driver. The LPC18xx SCU contain two registers that sets up the signal
routing to the GPIO pin interrupt (PINT) block. The routing uses the
GPIO namespace and not the pin namespace so a lookup is preformed on
the pin.

Routing configuration is done in the device tree by using the new
nxp,gpio-pin-interrupt property. This property takes single parameter
which sets the PINT hwirq for the GPIO.

In __request_region, if a conflict with a BUSY and MUXED resource is
detected, then the caller goes to sleep and waits for the resource to be
released.  A pointer on the conflicting resource is kept.  At wake-up
this pointer is used as a parent to retry to request the region.

A first problem is that this pointer might well be invalid (if for
example the conflicting resource have already been freed).  Another
problem is that the next call to __request_region() fails to detect a
remaining conflict.  The previously conflicting resource is passed as a
parameter and __request_region() will look for a conflict among the
children of this resource and not at the resource itself.  It is likely
to succeed anyway, even if there is still a conflict.

Instead, the parent of the conflicting resource should be passed to
__request_region().

As a fix, this patch doesn't update the parent resource pointer in the
case we have to wait for a muxed region right after.
