relatives are grouped together in their own section seems totally

The tps65910_irq_exit() cleanup function was generating a warning from

as the driver wasn't cleaning up its IRQs on exit at all so there was no

When the byte swap was factored out into the per-register I/O functions
the register restore for the IRQ mask cache (which we use and store in

swap when it uses the bulk I/O. Fix this by writing the cache out one
register at a time.

The WM831x AUXADC hardware can schedule multiple conversions at once,
allowing higher performance when more than one source is in use as we
can have the hardware start new conversions without having to wait for
a register write.

Take advantage of this in the interrupt driven case, maintaining a list of
callers that are waiting for AUXADC conversions and completing them all
simultaneously. The external interface of the AUXADC is not changed so
there will be limited use of the feature immediately.

This allows boards to leave the irq_base field unitialized and
prevents them having to reserve irqs in the platform.
pdata can be optional for irq support now. Without pdata the
driver allocates some free irq range. With pdata and irq_base > 0
the driver allocates exactly the specified irq.
Without pdata the irq defaults to IRQF_TRIGGER_LOW.
