Hi,

In this patchset v4,all the comments provided for patchset v3
are addressed.Also there is considerable
change in the code related to how the per port
uart structure is registerd with uart core.
so the patch [patch v4 1/5] considerably differs from [patch v3 1/5]

Thanks and Regards
Sudheer.V

changes in v4:
- since TX uart interrupt is being invoked by 8250 framework
  instead of expected TX DMA interrupt,registration of uart port is changed.
  per port uart structure registration is done directly now
  instead of going throgh 8250 framework.
  so there is considerable change in code against v3 patch
changes in v3:
- custom debugs replaced with pr_debug in 8250_ast2500_uart_dma.c
- change logs added in patches
