sh: Fix up more fallout from pointless ARM __iomem churn.

2012-10-15T05:08:48+00:00

It was already pointed out how to fix these cases before the offending
patches were merged, but unsurprisingly, that didn't happen. As this
change is entirely superfluous to begin with, simply shut things up by
casting everything away.

sh: intc: optimize intc IRQ lookup

2012-01-24T08:41:55+00:00

This ensures that the sense/prio lists are sorted at registration time,
enabling us to use a simple binary search for an optimized lookup
(something that had been on the TODO for some time).

sh: intc: Use IRQ_SET_MASK_OK_NOCOPY for intc_set_affinity.

2012-01-24T07:55:57+00:00

intc_set_affinity() updates the cpumask in place, so there's no need for
the upper layer to do this itself.

sh: intc: Kill off superfluous irq_shutdown hooking.

2012-01-24T06:38:57+00:00

This already gets handled via disable, as per the notes in linux/irq.h.

sh: intc: Prefer IRQCHIP_SKIP_SET_WAKE over a dummy set_wake callback.

2012-01-24T05:54:10+00:00

It's possible to use IRQCHIP_SKIP_SET_WAKE to get the behaviour that
we're after, without having to bother with a dummy ->set_wake() callback
for the IRQ chip.

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.

sh: intc: enable both edges GPIO interrupts on sh7372

2011-07-21T07:53:24+00:00

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.
