Input: goodix - fix compilation when ACPI support is disabled

2020-04-01T20:05:29+00:00

acpi_evaluate_object() and acpi_execute_simple_method() are not part of
the group of ACPI related functions which get stubbed by
include/linux/acpi.h when ACPI support is disabled, so the
IRQ_PIN_ACCESS_ACPI_METHOD handling code must be stubbed out.

For consistency use the same #if condition as which is used to replace
goodix_add_acpi_gpio_mappings with a stub.

Input: goodix - add support for more then one touch-key

2020-03-24T22:08:37+00:00

Some devices with a goodix touchscreen have more then 1 capacitive
touch-key. This commit replaces the current support for a single
touch-key, which ignored the reported key-code. With support for
up to 7 touch-keys, based upon checking the key-code which is
post-fixed to any reported touch-data.

KEY_LEFTMETA is assigned to the first touch-key (it will still be
the default keycode for devices with a single touch-key).
KEY_F1, KEY_F2... are assigned as default keycode for the other
touch-keys.

This commit also add supports for keycode remapping, so that
systemd-udev's hwdb can be used to remap the codes to send
keycodes to match the icons on the buttons for devices with more
then 1 touch-key.
