From 954111695cb7e27647ed9c150cac2f77d39c1e09 Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Wed, 18 Sep 2019 11:22:56 -0600 Subject: mb/google/hatch: Remove GPIO_DRIVER from pen eject GPIO configuration A closer read of the EDS indicates that when GPIO Driver mode is selected, GPIO input event updates are limited to GPI_STS only. GPI_GPE_STS updates are therefore masked, and we don't want to enable this behavior. It masks the GPE and does not allow us to see this GPE as a wake source, obscuring the reason that the system woke up. Also switch the IRQ from level-triggered to edge-triggered, otherwise the system will auto-wake from any sleep state when the pen is ejected from the garage. BUG=b:132981083 BRANCH=none TEST=Wake up system from S0ix using pen eject, verify that mosys eventlog shows GPE#8 as the S0ix wakeup source. Wake up system from S3 via pen eject, and verify that the wakeup source shows as GPE#8.
