ilsel_disable - Disable an ILSEL set : Bit position for ILSEL set value (retval from enable routines)

Disable a previously enabled ILSEL set.

int ilsel_enable

set

ilsel_enable - Enable an ILSEL set. : ILSEL source (see ilsel_source_t enum in include/asm-sh/ilsel.h).

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().

int ilsel_enable_fixed	(	ilsel_source_t	set,
		unsigned int	level
	)

ilsel_enable_fixed - Enable an ILSEL set at a fixed interrupt level : ILSEL source (see ilsel_source_t enum in include/asm-sh/ilsel.h). : Interrupt level (1 - 15)

Enables a given ILSEL source at a fixed interrupt level. Necessary both for level reservation as well as for aliased sources that only exist on special ILSEL::s.

Returns an IRQ number (as ilsel_enable()).
