v2 is based on the latest omap-serial runtime patches, which
can be found here[1]
The series passes minimal data that allows serial console
boot, with UART's initialised from device tree.
However some of low power support for UART and remote
wakeup needs more work.
Boot tested on OMAP4 panda and OMAP4 sdp boards.
Patches can be found here..

Changes in v2:
-1- Got rid of binding to define which uart is console
-2- Added checks to default clock speed to 48Mhz
-3- Added compatible for each OMAP family
-4- Used of_alias_get_id to populate port.line
regards,
Rajendra
