I took another look at using the DMA framework for this and I still
don't think it fits. The problem is that the DMA hardware is so
tightly coupled to the 8250 UART hardware that a generic DMA model
where a DMA engine will read the data from the UART data register when
Data Ready is asserted and tr

Add a UART driver for the new Broadcom 8250 based STB UART. The new
UART is backward compatible with the standard 8250, but has some
additional features. The new features include a high accuracy baud
rate clock system and DMA support.
The driver will use the new optional BAUD MUX clock to select t
