From 6f499069e8fac8c12a2e2872b51ea4ff43957eb8 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sat, 6 Jun 2015 11:52:24 +0300 Subject: sandy/ivy: Fix PIRQs on Chromebooks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This partially reverts commit 33b535f1. After this commit, samsung/lumpy had its internal USB EHCI controller broken, with no assigned IRQ. PIRQA-PIRQH may be wired as edge-triggered interrupts, making them exclusive for the GPIO to use. They cannot be used for PCI devices at the same time.
