This reverts commit ba40324261.
After commit 26d8cde526 ("pinctrl: freescale: imx: add shared
input select reg support"). i.MX7D has two iomux controllers
iomuxc and iomuxc-lpsr which share select_input register for
daisy chain settings.
If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call
devm_request_mem_region() for the region <0x30330000-0x3033ffff>
for the first time. Then, next time when probe the iomuxc, API
devm_platform_ioremap_resource() will also use the API
devm_request_mem_region() for the share region <0x30330000-0x3033ffff>
again, then cause issue, log like below:

has turned a 'pinctrl_register()' into 'devm_pinctrl_register()' in
'pxa2xx_pinctrl_init()'.
However, the corresponding 'pinctrl_unregister()' call in
'pxa2xx_pinctrl_exit()' has not been removed.
This is not an issue, because 'pxa2xx_pinctrl_exit()' is unused.

specifically treat the GPIO interrupts during suspend and resume, and
simply implement an irq_set_wake() callback that is responsible for
enabling the parent wake-up interrupt as a wake-up interrupt.

new_map = devm_kcalloc(pctldev->dev, map_num, sizeof(*new_map),

This uses devres and attaches new_map to the pinctrl driver.
This cause a leak since new_map is not released when the probed

These are called when a GPIO is to be used as IRQ.
Without these custom callbacks, when an interrupt is requested directly
and not through gpiod_to_irq(), the request fails because the GPIO is
not necesarily in input mode. These callbacks simply enforce that the
requested GPIO is in input mode.

Wakeup capable GPIO IRQs routed via PDC are not being migrated when a CPU

affinity of wakeup capable IRQs.

Use gpiochip_generic_config for the gpio_chip's set_config callback so
GPIO flags like GPIO_PULL_UP or GPIO_PULL_DOWN can be used in the board
.dts descriptions.
This is required for some Meson8m2 boards where GPIO_BSD_EN provides the
"MUTE" signal and requires enabling the internal pull-up resistor.

Currently, for EINT_TYPE GPIOs, the CON and FLTCON registers
are saved and restored over a suspend/resume cycle. However, the
EINT_MASK registers are not.
On S5PV210 at the very least, these registers are not retained over
suspend, leading to the interrupts remaining masked upon resume and
therefore no interrupts being triggered for the device. There should
be no effect on any SoCs that do retain these registers as theoretically
we would just be re-writing what was already there.

It's common across the drivers to use the (pin_base, npins) pair to describe
community characteristics. Thus, move them in the struct intel_community
to be closer to each other.
While at it, add a blank line to cut driver usable fields from what core
reserves for itself.

It appears that most of the drivers, that are using struct intel_community,
utilize gpps rather than gpp_size. Update comment accordingly.
While here, correct the description of gpp_size, i.e. remove double space
and drop redundant 'etc.' part.
