2021-11-27superio/smsc/sch5545: Disable PS/2 lines isolation during initMichał Żygowski
Disable PS/2 data and clock isolation in order to properly initialize the PS/2 keyboard and mouse in payload/OS. These bits are set by OS via ACPI and can survive S5 state. It is necessary to clear them after an ungraceful shutdown in order to perform PS/2 controller initialization e.g. in SeaBIOS. TEST=PS/2 keyboard can always be successfully initialized in SeaBIOS on Dell OptiPlex 9010 Signed-off-by: Michał Żygowski <michal.zygowski@3mdeb.com> Change-Id: Iac6be095c996b357b5d4e8d75199f94a89bf73e9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/59673 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
