d30a2b47d4 MIPS: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

a90295b488 gpio: zevio: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/gpio/Kconfig:config GPIO_ZEVIO
drivers/gpio/Kconfig:   bool "LSI ZEVIO SoC memory mapped GPIOs"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

9697643ff3 pinctrl: sh-pfc: Let gpio_chip.to_irq() return zero on error
Currrently the gpio_chip.to_irq() callback returns -ENOSYS on error,
which causes bad interactions with the serial_mctrl_gpio helpers.

mctrl_gpio_init() returns -ENOSYS if GPIOLIB is not enabled, which is
intended to be ignored by its callers. However, ignoring -ENOSYS when it
was caused by a gpiod_to_irq() failure will lead to a crash later:

    Unable to handle kernel paging request at virtual address ffffffde
    ...
    PC is at mctrl_gpio_set+0x14/0x78

Fix this by returning zero instead, like gpiochip_to_irq() does.

fd9c55315d gpio: of: make it possible to name GPIO lines
Make it possible to name the producer side of a GPIO line using
a "gpio-line-names" property array, modeled on the
"clock-output-names" property from the clock bindings.

This naming is especially useful for:

- Debugging: lines are named after function, not just opaque
  offset numbers.

- Exploration: systems where some or all GPIO lines are available
  to end users, such as prototyping, one-off's "makerspace usecases"
  users are helped by the names of the GPIO lines when tinkering.
  This usecase has been surfacing recently.

The gpio-line-names attribute is completely optional.

Example output from lsgpio on a patched Snowball tree:

GPIO chip: gpiochip6, "8000e180.gpio", 32 GPIO lines

0c0451e763 gpio: omap: fix irq triggering in smart-idle wakeup mode
Now GPIO IRQ loss is observed on dra7-evm after suspend/resume cycle
in the following case:
  extcon_usb1(id_irq) ->  pcf8575.gpio1 -> omapgpio6.gpio11 -> gic

the extcon_usb1 is wake up source and it enables IRQ wake up for
id_irq by calling enable/disable_irq_wake() during suspend/resume
which, in turn, causes execution of omap_gpio_wake_enable(). And
omap_gpio_wake_enable() will set/clear corresponding bit in
GPIO_IRQWAKEN_x register.

omapgpio6 configuration after boot - wakeup is enabled for GPIO IRQs
by default from  omap_gpio_irq_type:
GPIO_IRQSTATUS_SET_0    | 0x00000400
GPIO_IRQSTATUS_CLR_0    | 0x00000400
GPIO_IRQWAKEN_0         | 0x00000400
GPIO_RISINGDETECT       | 0x00000000
GPIO_FALLINGDETECT      | 0x00000400

omapgpio6 configuration after after suspend/resume cycle:
GPIO_IRQSTATUS_SET_0    | 0x00000400
GPIO_IRQSTATUS_CLR_0    | 0x00000400
GPIO_IRQWAKEN_0         | 0x00000000 <---
GPIO_RISINGDETECT       | 0x00000000
GPIO_FALLINGDETECT      | 0x00000400

As result, system will start to lose interrupts from pcf8575 GPIO
expander, because when OMAP GPIO IP is in smart-idle wakeup mode, there
is no guarantee that transition(s) on input non wake up GPIO pin will
trigger asynchronous wake-up request to PRCM and then IRQ generation.
IRQ will be generated when GPIO is in active mode - for example, some
time after accessing GPIO bank registers IRQs will be generated
normally, but issue will happen again once PRCM will put GPIO in low
power smart-idle wakeup mode.

Note 1. Issue is not reproduced if debounce clk is enabled for GPIO
bank.

Note 2. Issue hardly reproducible if GPIO pins group contains both
wakeup/non-wakeup gpios - for example, it will be hard to reproduce
issue with pin2 if GPIO_IRQWAKEN_0=0x1 GPIO_IRQSTATUS_SET_0=0x3
GPIO_FALLINGDETECT = 0x3 (TRM "Power Saving by Grouping the Edge/Level
Detection").

Note 3. There nothing common bitween System wake up and OMAP GPIO bank
IP wake up logic - the last one defines how the GPIO bank ON-IDLE-ON
transition will happen inside SoC under control of PRCM.

Hence, fix the problem by removing omap_set_gpio_wakeup() function
completely and so keeping always in sync GPIO IRQ mask/unmask
(IRQSTATUS_SET) and wake up enable (GPIO_IRQWAKEN) bits; and adding
IRQCHIP_MASK_ON_SUSPEND flag in OMAP GPIO irqchip. That way non wakeup
GPIO IRQs will be properly masked/unmask by IRQ PM core during
suspend/resume cycle.

296ad4acb8 gpio: remove deps on ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
The GPIOLIB symbol currently require that
ARCH_WANT_OPTIONAL_GPIOLIB or ARCH_REQUIRE_GPIOLIB is selected
to be selectable.

The ARCH_REQUIRE_GPIOLIB does only one thing: select GPIOLIB.

This is just confusing: architectures that want GPIOLIB should
be able to configure it in no matter what, and those who
require it should just select GPIOLIB.

It also creates problems for drivers that need to state
"select GPIOLIB" to get dependencies: those depend on the
selected architecture to select
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB first, and will cause
compile errors for the few archs that state neither.

These intermediary symbols need to go.

As a first step, remove the dependencies so that:

- ARCH_WANT_OPTIONAL_GPIOLIB becomes a noop (GPIOLIB will be
  available for everyone) and

- "select ARCH_REQUIRE_GPIOLIB" can be replaced by just
  "select GPIOLIB"

After this patch we can follow up with patches cleaning up the
architectures one-by one and eventually remove the
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB symbols altogether.
