commit 2243a87d
"pinctrl: avoid duplicated calling enable_pinmux_setting for a pin"
removed the .disable callback from the struct pinmux_ops,
making the .enable() callback the only remaining callback.

However .enable() is a bad name as it seems to imply that a
muxing can also be disabled. Rename the callback to .set_mux()
and also take this opportunity to clean out any remaining
mentions of .disable() from the documentation.

The AS3722_GPIO_INV bit will always be blindly overwritten by
as3722_pinctrl_gpio_set_direction() and will be ignored when
setting the value of the GPIO in as3722_gpio_set() since the
enable_gpio_invert flag is never set.  This will cause an
initially inverted GPIO to toggle when requested as an output,
which could be problematic if, for example, the GPIO controls
a critical regulator.

Instead of setting up the enable_gpio_invert flag, just leave
the invert bit alone and check it before setting the GPIO value.

If pins are used for function output like pwm, clk32k,
power good etc then set it as output mode default.

This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

The AS3722 is a compact system PMU suitable for mobile phones, tablets etc.

Add a driver to support accessing the GPIO, pinmux and pin configuration
of 8 GPIO pins found on the ams AS3722 through pin control driver and
gpiolib.

The driver will register itself as the pincontrol driver and gpio driver.
