sh: intc: Allow triggering on both edges for ARM SoCs

2011-11-04T15:57:48+00:00

Enable IRQ_TYPE_EDGE_BOTH on all R/SH-Mobile ARM SoCs.
This hardware feature is supported by sh7367, sh7377,
sh7372 and sh73a0.

sh: intc: Add IRQ trigger bit field check

2011-10-28T05:39:24+00:00

R-Mobile SoCs such as sh73a0 include PINT blocks in INTC
that come with 2-bit IRQ trigger support. Add code to make
sure the bit width is checked so 4-bit only modes like for
instance EDGE_BOTH will fail for PINT.

IRQ-capable GPIOs on sh7372 can be configured to produce interrupts on
both edges.

sh: update INTC to clear IRQ sense valid flag

2011-01-19T10:02:35+00:00

Clear the valid flag is in the INTC code.
Without this fix bit 7 of the sense register
is mistakenly set.

sh: intc: Split up the INTC code.

2010-10-05T13:10:30+00:00

This splits up the sh intc core in to something more vaguely resembling
a subsystem. Most of the functionality was alread fairly well
compartmentalized, and there were only a handful of interdependencies
that needed to be resolved in the process.

This also serves as future-proofing for the genirq and sparseirq rework,
which will make some of the split out functionality wholly generic,
allowing things to be killed off in place with minimal migration pain.
