From e0516a64e7ea9d9522d98f9f5f47aa38f147779f Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Wed, 2 Mar 2011 15:00:08 +0800 Subject: arm: pmu: allow platform specific irq enable/disable handling This patch introduces .enable_irq and .disable_irq into struct arm_pmu_platdata, so platform specific irq enablement can be handled after request_irq, and platform specific irq disablement can be handled before free_irq. This patch is for support of pmu irq routed from CTI on omap4.
