omap2_mcspi fixes + cleanups
McSPI functional updates:
- Implement the spi_transfer.delay_usecs mechanism (previously omitted).
- Remove strange per-device <asm/arch/mcspi.h> hookery ... it's not even
correct as a per-device config. We *always* want "single channel" mode
(in "keep chipselect active" mode); and if we used "turbo", it would
be a per-transfer option (as an rx-only double buffering tweak).
- When enabling/disabling a channel, old value is irrelevant; don't read.
- Sanity check spi->mode bits, and reject ones we don't support.
- Streamline DMA channel selection: do it once during probe(), using static
tables; smaller, faster. OMAP 2430 still needs changes here, minimally for
the third SPI controller. (Board init should change too, to not assume
all SPI controllers are used on every board...)
- Remove #ifdefs around doing reset on driver startup ... enable clocks
so we can do that (!), and turn on auto-idle.
- Waste less time enabling/disabling the clocks while working the queue.
- Flag DMA channels as freed when we do so ... so they can't get reused
later (when another driver may own them).
- Minor PIO fix: don't need to verify TX side completed except for TX_ONLY
mode, since RX completed implies TX completed.
- Remove bogus code which always dropped chipselect after the last RX_ONLY
word (rather than leaving it enabled).
- Move error checks out of work loop into setup() and transfer(), so that
they're reported ASAP rather than as mysterious transfer errors).
Plus a handful of cleanups: whitespace fixes, comments.
