init
In exynos_eint_wkup_init() the for_each_child_of_node() loop is used
with a break to find a matching child node. Although each iteration of
for_each_child_of_node puts the previous node, but early exit from loop
misses it. This leads to leak of device node.

Each iteration of for_each_child_of_node puts the previous node, but in
the case of a return from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put before the return of
exynos_eint_wkup_init() error path.
Issue found with Coccinelle.

devm_platform_ioremap_resource() internally have platform_get_resource()
and devm_ioremap_resource() in it. So instead of calling them separately
use devm_platform_ioremap_resource() directly.

If there is a problem with a pinctrl node of a device,
for example, config child node do not have prop specified in
dt_params, num_maps maybe 0. On this condition, no need remember
this map.

The get_direction api is strongly recommended to be implemented. In fact
if it is not implemented gpio-hogs will not get the correct direction.
Add an implementation of get_direction for the nsp-gpio driver.

Use more of the gpiolib infrastructure for handling interrupts. The
root interrupt still needs to be handled manually as it is shared with
other peripherals on the SoC.
This will allow multiple instances of this driver to be supported and
will clean up gracefully on failure thanks to the device managed APIs.

On SAM9X60, slewrate should be enabled on pins with a switching frequency
below 50Mhz. Since most of our pins do not exceed this value, we enable
slewrate by default. Pins with a switching value that exceeds 50Mhz will
have to explicitly disable slewrate.
This patch changes the ABI. However, the slewrate macros are only used
by SAM9X60 and, at this moment, there are no device-tree files available
for this platform.

Register 3 were accidentally copied from bit field [20], leading to

For the new Spreadtrum pin controller, it expands 6bits to describe the
pin sleep mode with adding one CM4_SLEEP mode, which means the pin sleep
related configuration will be loaded automatically by hardware when the
CM4 system goes into deep sleep mode.

The latent IRQs are IRQs that have occurred when the system
was down in deep sleep and the GPIO block was powered off.
The PRCMU (power reset and control unit) knows which GPIO
line offset fired an IRQ to wake the system up (if so
desired) and this second IRQ was used to replay the action
when the system came back online after suspend().
This is now known to be the wrong approach to solve this
problem: in a patch series Lina Iyer has suggested to
instead make it possible to model the IRQs as hierarchical
with double parents.
Also the current device trees do not contain the right
information to make this code work, the latent IRQ is not
specified nowadays giving noise like this in the console:
[ 0.612168] gpio 8012e000.gpio: IRQ index 1 not found
[ 0.622523] gpio 8012e080.gpio: IRQ index 1 not found
Let's delete the latent IRQ code and reimplement it properly
when we need it.

When an STMFX IO is used as interrupt through the interrupt-controller
binding, the STMFX driver should configure this IO as input. Default
value of STMFX IO direction is input, but if the IO is used as output
before the interrupt use, it will not work without these callbacks.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.
For chained irqchips this is a pretty straight-forward
conversion: the ST pin controller errors out of adding a
irqchip if the interrupt is invalid or missing or if the
irqmux is not present: the irqchip should not be added
if either of these errors happen, so rewrite the code to
deal with that. Keep the exit path where the gpio_chip
is added no matter what the status of the irq is.

For chained irqchips this is a pretty straight-forward
conversion: at91 is a little bit special since it registers
up to 3 gpio_chips with the same parent handler, but just
passing girq->parent_handler and the parent on the first
of them should cut it.

The call to pinctrl_count_index_with_args checks for a -EINVAL return
however this function calls pinctrl_get_list_and_count and this can
return -ENOENT. Rather than check for a specific error, fix this by
checking for any error return to catch the -ENOENT case.
