From e271f6c2df78d60dd4873c790a51dba40e6dfb72 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 28 Apr 2020 16:22:53 +0200 Subject: [PATCH] HID: asus: Add support for multi-touch touchpad on Medion Akoya E1239T The multi-touch touchpad found on the Medion Akoya E1239T's keyboard-dock, uses the same custom multi-touch protocol as the Asus keyboard-docks (same chipset vendor, Integrated Technology Express / ITE). Add support for this using the existing multi-touch touchpad support in the hid-asus driver.
