[PATCH 4/4] arm: Kconfig: allow OMAP to use sparse IRQ numbering

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Select HAVE_SPARSE_IRQ to allow OMAP to use
sparse IRQ numbering scheme. The main difference
is that irq_descs will be added to a radix tree
instead of a static array.
