From 8832de380d3e53f556c1b04818f324ea1ac1d415 Mon Sep 17 00:00:00 2001 From: Karthikeyan Ramasubramanian Date: Mon, 14 Dec 2020 00:13:28 -0700 Subject: mb/google/dedede/var/boten: Update LTE GPIO configuration LTE module is not expected to be powered off during warm reset. Hence configure the LTE_PWR_OFF_ODL (GPP_A10) gpio pad reset configuration to PWROK and set the TX state to 1. BUG=b:163100335 BRANCH=dedede TEST=Verified through the waveforms that power sequence is meeting the LTE module requirements.
