Input: gpio_tilt - delete driver
This driver was merged in 2011 as a tool for detecting the orientation
of a screen. The device driver assumes board file setup using the
platform data from <linux/input/gpio_tilt.h>. But no boards in the
kernel tree defines this platform data.
As I am faced with refactoring drivers to use GPIO descriptors and
pass decriptor tables from boards, or use the device tree device
drivers like these creates a serious problem: I cannot fix them and
cannot test them, not even compile-test them with a system actually
using it (no in-tree boardfile).
I suggest to delete this driver and rewrite it using device tree if
it is still in use on actively maintained systems.
I can also offer to rewrite it out of the blue using device tree if
someone promise to test it and help me iterate it.
