From 9a14fab340b4c8e0afd8bf04746f51ea189fdf5f Mon Sep 17 00:00:00 2001 From: Krishna Prasad Bhat Date: Fri, 7 Jan 2022 16:39:53 +0530 Subject: mb/intel/adlrvp_n: Configure EC in RW GPIO EC_IN_RW signal from EC GPIO is connected to GPIO E7 of SOC. This GPIO can be used to check EC status trusted (LOW: in RO) or untrusted (HIGH: in RW). BRANCH=None BUG=None TEST=Issue manual recovery and confirm DUT is entering recovery mode.
