This fixes the build warning , warning: cast from pointer to integer
of different size when building this file on a x86 allmodconfig
configuration. In order for me to fix this build warning I changed
the cast in the function mmio_74xx_gpio_probe from casting the
variable data of the stucture pointer of_id to uintptr_t rather
then unsigned when assigning to the variable flag of the structure
pointer priv of the structure type mmio_74xx_gpio_priv.

In case the gpiochip doesn't have the .dev field set, as is the case
in here, it is not possible to reference this device in DT as a GPIO
controller. A good example of this problem is that gpio-leds can not
be used when connected to this chip, the gpio-leds driver bails out
with -EPROBE_DEFER.
Fix this problem by setting the .dev field of the gpio_chip to the
parent i2c device.

xgpio_save_regs() is used in this driver to setup the initial
values of the registers in the hardware.
The relevant registers at that time are:
0x0 -> channel 0 data (32 bits, one for each GPIO on this channel).
0x4 -> channel 0 tri, controls in/out status for each GPIO of this channel.
0x8 -> channel 1 data
0xC -> channel 1 tri
gpio-xilinx.c defines these:
XGPIO_DATA_OFFSET (0x0)
XGPIO_TRI_OFFSET (0x4)
XGPIO_CHANNEL_OFFSET 0x8
Before this patch, the "data" register value of channel 1 was written
at 0x4 intead of 0x8 (overwriting the channel 0 "tri" register),
and the "tri" register value for channel 1 was written at 0x8 instead of 0xC.

Now nothing prevents GPIO driver from being unloaded if its gpios
were requested as GPIO IRQs only (without calling gpio_request()).
Hence, add calls of try_module_get()/module_put() into
gpiochip_irq_reqres/relres() to track such scenario properly.

The spinlock 'slock' is used now to protect pcf857x_irq() from itself
which is unnecessary (especially after switching to use threaded
IRQs). Hence, remove it and use mutex to protect device data in IRQ

Currently gpio modules are runtime-resumed at probe time. This means the
gpio module will be active all the time (except during system suspend,
if not configured as a wake-up source).
While an R-Car Gen2 gpio module retains pins configured for output at
the requested level while put in standby mode, gpio registercannot be
accessed while suspended. Unfortunately pm_runtime_get_sync() cannot be
called from all contexts where gpio register access is needed. Hence
move the Runtime PM handling from probe/remove time to gpio request/free
time, which is probably the best we can do.
On r8a7791/koelsch, gpio modules 0, 1, 3, and 4 are now suspended during
normal use (gpio2 is used for LEDs and regulators, gpio5 for keys, gpio6
for SD-Card CD & WP, gpio7 for keys and regulators).

If a failure occurs during probe, brcmstb_gpio_remove() is called. In
remove, we call platform_get_drvdata(), but at the time of failure in
the probe the driver data hadn't yet been set which leads to a NULL
ptr dereference in the remove's list_for_each. Call
platform_set_drvdata() and set up list head right after allocating the
priv struct to both avoid the null pointer dereference that could
occur today. To guard against potential future changes, check for
null pointer in remove.

- A big cleanup of the Marvell MVEBU driver rectifying it to
correspond to reality
- Drop platform device probing from the SH PFC driver, we are now a
DT only shop for SuperH
- Drop obsolte multi-platform check for SH PFC
- Various janitorial: constification, grammar etc
Improvements:
- The AT91 GPIO portions now supports the set_multiple() feature
- Split out SPI pins on the Xilinx Zynq
- Support DTs without specific function nodes in the i.MX driver"

Commit 8a0662d9 introduced of_node and acpi_node symbols in global namespace
but there were already ~63 of_node local variables or function parameters
(no single acpi_node though, but anyway).
After debugging undefined but used of_node local varible (which turned out
to reference static function of_node() instead) it became clear that the names
for the functions are too short and too generic for global scope.
