From d6a1f863433bdf3f8406dedfa33fa79ee9259db3 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 6 May 2011 11:02:45 +0000 Subject: [PATCH] mmc: sdhi: support up to 3 interrupt sources Convert the SDHI code to support more than a single interrupt source. Needed to support hardware that uses GIC instead of INTC as interrupt controller. Will also allow us to remove the irq forwarding workaround from the INTC code in the future.
