From c3cef7e7b00648ac72a714c94b09a66095e51473 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Wed, 21 Dec 2022 12:22:21 -0600 Subject: mb/google/dedede: Use runtime detection for touchscreens Now that power sequencing has been implemented, switch from using ACPI "probed" flag to "detect" flag for all i2c touchscreens. This removes non-present devices from the SSDT and relieves the OS of the burden of probing. BUG=b:121309055 TEST=build/boot Windows/linux on multiple dedede variants, verify all touchscreens functional in OS, dump ACPI and verify only i2c devices actually present on the board have entries in the SSDT.
