Paul Mundt 0dd4d5cbe4 sh: Fix up more fallout from pointless ARM __iomem churn.
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.

Paul Mundt b59f9f9775 sh: intc: optimize intc IRQ lookup
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).

Paul Mundt 3037764213 sh: intc: Use IRQ_SET_MASK_OK_NOCOPY for intc_set_affinity.
intc_set_affinity() updates the cpumask in place, so there's no need for
the upper layer to do this itself.

Paul Mundt 29775df10f sh: intc: Kill off superfluous irq_shutdown hooking.
This already gets handled via disable, as per the notes in linux/irq.h.

Paul Mundt 5bbda4e4ac sh: intc: Prefer IRQCHIP_SKIP_SET_WAKE over a dummy set_wake callback.
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.

Magnus Damm 7d377b170a sh: intc: Allow triggering on both edges for ARM SoCs
Enable IRQ_TYPE_EDGE_BOTH on all R/SH-Mobile ARM SoCs.
This hardware feature is supported by sh7367, sh7377,
sh7372 and sh73a0.

Magnus Damm 52e3124f24 sh: intc: Add IRQ trigger bit field check
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.

Magnus Damm 8a5a778665 sh: update INTC to clear IRQ sense valid flag
Clear the valid flag is in the INTC code.
Without this fix bit 7 of the sense register
is mistakenly set.

Paul Mundt 2be6bb0c79 sh: intc: Split up the INTC code.
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.
