From 477942e2536ccadf77d4acfb6b91bb82e6771ad4 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Sat, 15 Jul 2017 14:13:37 -0700 Subject: mb/google/eve: Remove ACPI control of touchscreen power Change the touchscreen power control back to coreboot instead of under the ACPI _ON/_OFF methods, and switch the TOUCHSCREEN_STOP_L pin back to an output. This reverts previous changes to touchscreen GPIOs that were made to get back to a known good/working state. Having ACPI control these pins was resulting in a small percentage of touchscreen not being discovered at boot. This platform is not intending to use S0ix so the ACPI control is not needed. BUG=b:63718744 TEST=manual testing on Eve devices.
