From 5a3ff8473c9100adb06d60e52477668d1504e8cf Mon Sep 17 00:00:00 2001 From: "Cousson, Benoit" Date: Tue, 28 Feb 2012 14:10:09 +0100 Subject: ARM: OMAP: irqs: Fix NR_IRQS value to handle PRCM interrupts The following commit: 2f31b51659c2d8315ea2888ba5b93076febe672b Author: Tero Kristo Date: Fri Dec 16 14:37:00 2011 -0700 ARM: OMAP4: PRM: use PRCM interrupt handler introduced the PRCM interrupt handler and thus the need for 64 more interrupts. Since SPARSE_IRQ is still not fully functional on OMAP, the NR_IRQS needs to be updated to avoid the failure that happen during irq_alloc_descs call inside the PRCM driver: [ 0.208221] PRCM: failed to allocate irq descs: -12 Later the mux framework is then unable to request an IRQ from the PRCM interrupt handler. [ 1.802795] mux: Failed to setup hwmod io irq -22 Fix that by adding 64 more interrupts for OMAP2PLUS config.
