Hi guys,

here's a series of cleanup patches to the OMAP serial
driver. A later series could be made re-implementing
DMA using the DMA Engine API. Note that for RX DMA
we could be using RX Timeout IRQ as a hint that we better
use PIO instead ;-)

All patches were tested on my pandaboard, but I'd really
like to receive Tested-by on other platforms.

After this goes in, I'll probably try to get UART wakeup
working again and only after that look at DMA.

cheers

Felipe Balbi (13):
  serial: omap: define and use to_uart_omap_port()
  serial: omap: always return IRQ_HANDLED
  serial: omap: define helpers for pdata function pointers
  serial: omap: don't access the platform_device
  serial: omap: drop DMA support
  serial: add OMAP-specific defines
  serial: omap: simplify IRQ handling
  serial: omap: refactor receive_chars() into rdi/rlsi handlers
  serial: omap: move THRE check to transmit_chars()
  serial: omap: stick to put_autosuspend
  serial: omap: set dev->drvdata before enabling pm_runtime
  serial: omap: drop unnecessary check from remove
  serial: omap: make sure to suspend device before remove

Apart from that one question on last patch, rest of the clean-up
is really good. Nice work.

FWIW,
