From 61c24461421b5b1953840962115af808b6f43843 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Mon, 19 Dec 2022 15:13:47 -0600 Subject: [PATCH] mb/google/guybrush: update ACPI HID/CID for Synaptics touchpad The currently assigned ACPI HID 'PNP0C50' is not a valid per Windows WHQL validation tests. To ensure compatibility with both Windows and Linux, set the HID to 'SYNA0000' and CID to 'ACPI0C50' as previously done for other boards (eg, google/lulu). TEST=boot ChromeOS, Linux 5.1x, Windows 10 on dewatt, verify all touchpad functions work correctly.
