[PATCH v2 0/7] serial: 8250_omap: workaround for IP errata

[Sekhar Nori <nsekhar-l0cyMroinI0@public.gmane.org>]

This series works around "Advisory 21" as documented in
AM437x SoC errata[1]. This errata prevents UART module
from idling after DMA is used. AM335x and DRA7x also suffer
from the same errata and chip design team is in the process
of updating the errata documents of those devices as well.

Patch 1/7 fixes a related bug but can be applied independently.
