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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
In the multi-evt case we were accidentally associating the parent IRQ, fix this up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
Presently it's assumed that the irqdomain code handles the irq_desc allocation for us, but this isn't necessarily the case when we've pre-allocated IRQs via sparseirq. Previously we had a -EEXIST check in the code that attempted to trap these cases and simply update them in-place, but this behaviour was inadvertently lost in the transition to irqdomains. This simply restores the previous behaviour, first attempting to let the irqdomain core fetch the allocation for us, and falling back to an in-place domain association in the extant IRQ case. Fixes up regressions on platforms that pre-allocate legacy IRQs (specifically ARM-based SH-Mobile platforms, as SH stopped pre-allocating vectors some time ago).

Trivial support for irq domains, using either a linear map or radix tree depending on the vector layout. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
This switches to using irq_alloc_desc() directly for subgroup IRQs. We still need to call activate_irq() on these in order to make them requestable, at least up until these get moved in to their own irq domain.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
Now that all of the users have been converted away, kill off the remnants of the old API. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

intc_ack_data is flagged as __init when it shouldn't be, causing section mismatches in non-init paths like intc_set_ack_handle(): WARNING: drivers/built-in.o(.text+0x5d760): Section mismatch in reference from the function intc_set_ack_handle() to the function .init.text:intc_ack_data() The function intc_set_ack_handle() references the function __init intc_ack_data(). This is often because intc_set_ack_handle lacks a __init annotation or the annotation of intc_ack_data is wrong.

SH intc has a compile time dependency on NR_IRQS. Make this dependency a local define so that shmobile (and ARM in general) can have run-time NR_IRQS setting. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
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). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
