ILSEL_ENABLE(9) 					    Machine Specific Interfaces 					   ILSEL_ENABLE(9)

NAME
       ilsel_enable - Enable an ILSEL set.

SYNOPSIS
       int ilsel_enable(ilsel_source_t set);

ARGUMENTS
       set
	   ILSEL source (see ilsel_source_t enum in include/asm-sh/ilsel.h).

DESCRIPTION
       Enables a given non-aliased ILSEL source (<= ILSEL_KEY) at the highest available interrupt level. Callers should take care to order
       callsites noting descending interrupt levels. Aliasing FPGA and external board IRQs need to use ilsel_enable_fixed.

       The return value is an IRQ number that can later be taken down with ilsel_disable.
