From c806e4cc59208afb8b00da0a2cd34909e6bb9fb3 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Fri, 28 Oct 2016 09:07:49 -0700 Subject: [PATCH] skylake: Add GPIO macro for configuring inverted APIC input Add a GPIO macro that allows a pin to be routed to the APIC with the input inverted. This allows a normal interrupt to get used as a GPE during firmware and still be used as a perhiperal interrupt in the kernel.
