The earlier patch can be simplified by using a bool
to indicate level trigger.

In the function amd_gpio_irq_set_type, use the settings provided by
the BIOS,when the LevelTrig is Edge and activeLevel is HIGH, to configure
the GPIO registers. Ignore the settings from client.

In the function amd_gpio_irq_enable() and
amd_gpio_direction_input(), remove the code which is setting
the default de-bounce time to 2.75ms.

The driver code shall use the same settings as specified in
BIOS. Any default assignment impacts TouchPad behaviour when
the LevelTrig is set to EDGE FALLING.

Use devm_pinctrl_register() for pin control registration and clean

Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since
it does not depend on device tree despite the current name. This
will enforce a consistent naming in pinctr-utils.c and will make
it clear it can be called from outside device tree (e.g. from
ACPI handling code).

Add device HID AMDI0030 to match the AMD ACPI Vendor ID (AMDI) as
registered in http://www.uefi.org/acpi_id_list, and the GPIO controller
on future AMD paltform will use the HID instead of AMD0030.

In case of error, the function devm_ioremap_nocache() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

The name .dev in a struct is normally reserved for a struct device
that is let us say a superclass to the thing described by the struct.
struct gpio_chip stands out by confusingly using a struct device *dev
to point to the parent device (such as a platform_device) that
represents the hardware. As we want to give gpio_chip:s real devices,
this is not working. We need to rename this member to parent.

This was done by two coccinelle scripts, I guess it is possible to
combine them into one, but I don't know such stuff. They look like
this:

@@
struct gpio_chip *var;
@@
-var->dev
+var->parent

and:

@@
struct gpio_chip var;
@@
-var.dev
+var.parent

and:

@@
struct bgpio_chip *var;
@@
-var->gc.dev
+var->gc.parent

Plus a few instances of bgpio that I couldn't figure out how
to teach Coccinelle to rewrite.

This patch hits all over the place, but I *strongly* prefer this
solution to any piecemal approaches that just exercise patch
mechanics all over the place. It mainly hits drivers/gpio and
drivers/pinctrl which is my own backyard anyway.
