From 2d602098f9def150d1111f334a668391c25da5cf Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Wed, 5 Sep 2018 13:59:00 -0700 Subject: mb/google/octopus: Configure H1 interrupt pad using Rx level config This change configures GPIO_63 (which is used for H1 interrupts) as Rx Level. This ensures that the signal gets passed on to the next logic state as is and the APIC entry can be configured to trigger interrupt on level or edge as per the kernel driver expectation. TEST=Verified that no H1 interrupt timeouts are seen with 100 iterations of warm and 100 iterations of cold reboot.
