Paul Mundt bec36eca6f sh: hd64461: Fix up I/O base register offsets.
hd64461 is mapped in a fixed location, so the I/O base itself is fairly
meaningless as a configuration item. Additionally, this makes it
impossible to share hd64461 code alongside generic drivers (in the case
of sh_dac_audio), so simply make it commonly defined and permit the
mach_is_foo() logic to work out the proper semantics.

Matt Fleming 135210b378 sh: Switch HD64461 from hw_interrupt_type to irq_chip
Use struct irq_chip for the interrupt handler for the HD64461. Also
convert some in{b,w} and out{b,w} calls to the equivalent __raw_* calls.
Include <linux/io.h> and not <asm/io.h> to stop checkpatch.pl
complaining.

This change should now allow machines with HD64461 to define
GENERIC_HARDIRQS_NO__DO_IRQ.

Paul Mundt 3eeebf17f3 sh: Kill off long-dead HD64465 cchip support.
This code has been dead for many years. The last update it received
was in 2003 in order to update it for the driver model changes, though
it had already been in disarray and unused before that point. The only
boards that ever used this chip have not had users in many years either,
so it is finally safe to just kill it off and move on with life.

Magnus Damm 7f3edee81f sh: intc - remove default interrupt priority tables
This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.

The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

- Speedup sense and priority configuration code
- Allocate data using bootmem, allows intc data structures to be

Magnus Damm 48180cab3a sh: intc - convert voyagergx code
This patch converts the sh-specific voyagergx interrupt code to make use
of intc. A lot of "interesting" old cruft gets replaced with intc tables
and some simple demux code.

- All interrupt sources in the sm501 data sheet are now in the header.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 200.
- set_irq_chained_handler() is now used to hook up the demux function.

In the future it would probably make sense to move the interrupt demuxer
into into the mfd driver, but this is probably a nice step in the right
direction until that happens.

Tested on a R2D-1 board using the serial port hooked up to the sm501.

Ingo Molnar d1bef4ed5f [PATCH] genirq: rename desc->handler to desc->chip
This patch-queue improves the generic IRQ layer to be truly generic, by adding
various abstractions and features to it, without impacting existing
functionality.

While the queue can be best described as "fix and improve everything in the
generic IRQ layer that we could think of", and thus it consists of many
smaller features and lots of cleanups, the one feature that stands out most is
the new 'irq chip' abstraction.

The irq-chip abstraction is about describing and coding and IRQ controller
driver by mapping its raw hardware capabilities [and quirks, if needed] in a
straightforward way, without having to think about "IRQ flow"
(level/edge/etc.) type of details.

This stands in contrast with the current 'irq-type' model of genirq
architectures, which 'mixes' raw hardware capabilities with 'flow' details.
The patchset supports both types of irq controller designs at once, and
converts i386 and x86_64 to the new irq-chip design.

As a bonus side-effect of the irq-chip approach, chained interrupt controllers
(master/slave PIC constructs, etc.) are now supported by design as well.

The end result of this patchset intends to be simpler architecture-level code
and more consolidation between architectures.

We reused many bits of code and many concepts from Russell King's ARM IRQ
layer, the merging of which was one of the motivations for this patchset.

This patch:

rename desc->handler to desc->chip.

Originally i did not want to do this, because it's a big patch.  But having
both "desc->handler", "desc->handle_irq" and "action->handler" caused a
large degree of confusion and made the code appear alot less clean than it
truly is.

I have also attempted a dual approach as well by introducing a
desc->chip alias - but that just wasnt robust enough and broke
frequently.

So lets get over with this quickly.  The conversion was done automatically
via scripts and converts all the code in the kernel.

This renaming patch is the first one amongst the patches, so that the
remaining patches can stay flexible and can be merged and split up
without having some big monolithic patch act as a merge barrier.
