Subject: [PATCH 0/1] Enable touchpad for Lenovo 13x ThinkBook Gen 4 (GT7868Q)
Date: Tue, 16 Jul 2024 23:27:56 +0100 [thread overview]
Message-ID: <20240716222757.22931-1-envelsavinds@gmail.com> (raw)
Hi,
This patch adds Goodix GT7868Q device support to hid-multitouch.
The device is used on Lenovo ThinkBook 13x Gen 4 series of laptops
and have incorrect descriptor that hid-parse fails to parse
hence device is not working.
Terry Wong made a driver (fixup) that uses report_fixup to correct
the values in the descriptor. This is mostly re-using hid-multitouch
code. With his permission, I added the fixup to the driver itself.
Open to the feedback if there's a better approach to solving
the issue.
