[RFC] [PATCH 0/2] High Speed uart support on 3430

[Girish]

Hi,
This patch series adds high speed uart support on 3430. 

UART library Interfaces:
The UART library interfaces the user drivers with UART hardware and exports API’s to configure UART for different types of
applications such as High speed(HS) UART, IrDA and Bluetooth etc. 
The most of the API’s exported by UART library are functionality based API’s which are used by client drivers for different purposes
such as 
-	Requesting UART
-	Initial UART configuration
-	Data transfer Configuration(DMA mode)
-	ISR registration
-	UART Speed change


Regards,
Girish

Well all that sounds good, but please move the driver to drivers/serial
to start with.

This UART driver is more like an independent library which doesn't interface with serial framework so this might not fit in
driver/serial. Any comments?

Is it possible to make a driver for omap uarts based on your library? 
Current generic drivers seems to trigger some hw(?) bugs, so at least in 
  we had to use custom serial driver. Also working power management was 
added so that clock are not used when the uart is not actually used.
