[PATCH v2 00/12] HID: asus: add support for ROG Ally handhelds

[Denis Benato]

Hi all,

This patch series adds support for ROG Ally handhelds in the HID driver for
ASUS devices.

The changes include reinitialization of the device after exiting a sleep state,
gamepad configuration, vibration strength configuration, joysticks and triggers
range configuration, anti-deadzone configuration, response curve support,
force feedback support, gamepad mode support, turbo buttons support,
and button remapping support.

This driver is based on the original Luke's work, which was a great starting point
and I have reworked it to be upstreamable, while keeping the original functionality
intact and extending hid-asus to avoid regressions in functionality such as the
backlight control.

The ally support has been a surprisingly long task, spanning multiple years and
being used in Steam OS and well as other distributions for quite a while,
and I am happy to finally be submitting it.

At this time LEDs are not part of the patch series as I have work in progress to
unify LEDs handling across all ASUS devices, and I will submit that in a separate
patch series when the userspace interface will be ready to express capabilities
of these devices, but that will take some more time.

This driver is the culmination of a lot of work, from many different people,
and I want to thank Luke for his original work, as well as the many people that have
helped me test and provide feedback on the driver: Khamunetri, Jonathan, Derek,
Matthew and others that have helped during these years.

Best regards,
Denis Benato
