From f01b1f90bf46ddaf2a68215a9489364c974e5689 Mon Sep 17 00:00:00 2001 From: Benoit Cousson Date: Wed, 29 Feb 2012 22:38:06 +0100 Subject: mfd: Make twl4030 SIH SPARSE_IRQ capable twl4030 is using a two level irq controllers infrastruture. So far, only the first level was using dynamic irq_desc allocation to be able to have irq_domain support for device tree. There is a need to allocate separate irq_descs for the SIH too to avoid hacking the first level with interrupts from the second level. Add an irq_base parameter to allow the caller to provide the base from pdata or from dynamic allocation. Affect TWL4030_NR_IRQS to the twl-core IRQs only. Moreover that will allow the extraction of the of_node pointer for further Device Tree conversion.
