This patch series brings a better support of the ports found on Intel Penwell SoCs. Besides it does a good clean up it allows to provide support for newer Intel SoCs that use same IP, such as Intel Tangier, though it's not a part of this series. The differences to current implementation: - the HSU DMA driver is written using DMAEngine framework since 8250 supports latter - DMA driver uses all for accessible descriptors when former relied only on one (this increases performance of DMA) - the copy of the most functionality of the 8250 is removed (the old tty/serial/mfd.c driver) The series had been tested on Intel Medfield and Edison boards. Note that the serial device name is changed from a non-standard ttyMFDx to ttySx. Greg, I hope it will be no objection from you to pass this through tty tree. So, it would nice to have an Ack from you, Vinod.
