From 58c063ebd099e94a45da8c0c6ba48b0128a59b03 Mon Sep 17 00:00:00 2001 From: Maulik V Vaghela Date: Fri, 10 Jun 2022 19:55:24 +0530 Subject: mb/google/nissa: Skip locking for GPP_F14 GPIO There is an existing issue for nissa boards where wake up from RTC wake is not working during suspend_stress_test. This issue was root caused to the patch which was setting GPE_EN bits for the GPIOs before locking. Reference: https://review.coreboot.org/c/coreboot/+/64089 Later issue was found to be with GPP_F14 configuration for nissa boards. When coreboot skips setting GPE_EN bit for GPP_F14, RTC wake works properly. Another way to make it work is to skip locking GPP_F14 GPIO to allow kernel to configure it properly. This patch skips the locking for GPP_F14 to allow kernel to configure it later. This fixes the issue of RTC wake not working. Note: This patch provides workaround for the existing issue and BUG will be closed once actual reason is identified and proper fix is available. BUG=b:234097956 BRANCH=None TEST=RTC wake works on Nivviks board with the patch.
