2011-11-05sh: intc: Allow triggering on both edges for ARM SoCsMagnus Damm
Enable IRQ_TYPE_EDGE_BOTH on all R/SH-Mobile ARM SoCs. This hardware feature is supported by sh7367, sh7377, sh7372 and sh73a0. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-10-28sh: intc: Add IRQ trigger bit field checkMagnus Damm
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.

2011-07-21sh: intc: enable both edges GPIO interrupts on sh7372Magnus Damm
IRQ-capable GPIOs on sh7372 can be configured to produce interrupts on both edges. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-01-19sh: update INTC to clear IRQ sense valid flagMagnus Damm
Clear the valid flag is in the INTC code. Without this fix bit 7 of the sense register is mistakenly set. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-10-05sh: intc: Split up the INTC code.Paul Mundt
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.
