From c0a239233331f7d6d2256dde80cb19fd6f9b3542 Mon Sep 17 00:00:00 2001 From: Jens Rottmann Date: Mon, 5 Mar 2012 15:07:54 -0800 Subject: [PATCH] cs5535-clockevt: Allow the MFGPT IRQ to be shared Shared timer IRQs are not a good solution, however the Geode platform has no APIC, IRQs are a scarce resource and there is no technical reason to forbid it rightaway. Increased latencies and overhead due to sharing are still better than a driver refusing to load.
