From e33b67523f556aa7ddb09f1c7fa4de5c080670c9 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 12 Mar 2015 08:40:37 +0000 Subject: [PATCH] ARM: imx6: Allow GPC interrupts affinity to be changed While converting the GPC code to a stacked irqchip, we lost the possibility to change the CPU affinity of an interrupt routed through the GPC. This patch restore the expected behaviour by forwarding the affinity setup to the underlying irqchip (GIC).
