If a device is part of the wake-up path, it should indicate this by
setting its power.wakeup_path field.  This allows the genpd core code to
keep the device enabled during system suspend when needed.

As regulators powering devices are not handled by genpd, the driver
handles these itself, and thus must skip regulator control when the
device is part of the wake-up path.

Simple string comparisons are cheaper than DT lookups, as the latter
involve taking a spinlock and traversing properties.
Hence optimize quirk checks by postponing DT lookups after string
comparisons.

Linux 5.1-rc3

The direction inversion semantics are now handled by simply
using the registers for in/out available, no need to keep
track of inversion semantics exmplicitly anymore.

During my regression testing I noticed the cadence GPIO driver
fails on the latest gpio for-next tree.

I think the reason is this patch:
commit 96cd559817f2 ("Merge branch 'devel' into for-next")

Here is a part of the test log:

Loopback 8 -> 24
TESTING: gpio: 488: output direction PASSED
TESTING: gpio: 504: input direction PASSED
TESTING: gpio: 488: 0 PASSED
TESTING: gpio: 488 -> 504: 0 PASSED
TESTING: gpio: 488: 1 FAILED
TESTING: gpio: 488 -> 504: 1 FAILED
TESTING: gpio: 488: 0 PASSED
TESTING: gpio: 488 -> 504: 0 PASSED

It looks like the issue is that gc->bgpio_dir has changed its meaning.
It used to be set to the register value (so it was being inverted).

Now it's always set to 1 for output and 0 for input.
However the bgpio_get_set functions were not updated.
So they invert the bit again, which means a wrong register
is being accessed.

This patch fixes that by removing the unnecessary inversion.

The gpio_set_config function creates a pinconf configuration for a given
pinc_config_param.

However, it always uses an arg of 0, which might not be a valid argument
for a given param. A good example of that would be the bias parameters,
where 0 means that the pull up or down resistor is null, and the pin is
directly connected to VCC/GND.

The framework uses in some other places the value 1 as a default argument
to enable the pull resistor, so let's use the same one here.

clang warns about a tentative array definition in the gpio-omap driver:

drivers/gpio/gpio-omap.c:1282:34: error: tentative array definition assumed to have one element [-Werror]
static const struct of_device_id omap_gpio_match[];

It's best to just reorder the entire file to avoid forward declarations,
which lets us use the regular declaration. To do this, the unnecessary
CONFIG_OF check must also be removed.

The comment for this dbg_show says that it is supposed to return more
than what the generic code is showing, including de-glitching. That's
wrong because:

- this chip does not support deglitching,
- the code does not print anything extra compared to the generic
handler,
- its behavior is different because it skips unrequested GPIOs; the
generic code prints their names if they're assigned

There is an important difference, though. Previously, dbg_show would
re-check some registers to see if they still match what the regmap
thinks should be in there. This was semi-useful when develpoing the HW
board because it immediately pointed to SPI wiring problem if a CS
connection was missing (0xffs are easy to see). However, I do not think
that this makes much sense -- and one could always do this in some other
way if needed.
