From 8fcd559ef9780bb1f8a81e4fcf2985782b01817a Mon Sep 17 00:00:00 2001 From: Divya Chellap Date: Wed, 25 Oct 2017 16:34:11 +0530 Subject: soraka: update pad reset config of WLAN_PE_RST to RSMRST In skylake based platforms, setting GPIO pad reset config to DEEP will reset the gpio configuration across warm reset, set it to RSMRST to preserve the configuration across warm resets. Also, moving the configuration from early to late as appropriate. BUG=b:64386481 BRANCH=none TEST= WiFi functionality across S3, DeepS3, S0ix and warm/cold reboot.
