This series of patches fix many bugs:
- a wrong enum type was used when calling dma_sync_*_for_cpu() and
dma_sync_*_for_device()
- IO accesses to registers were done in atmel_serial_probe() after the
peripheral clock had been disabled.
- the -EDEFER error was not handled properly in atmel_serial_probe()
- the Hardware Handshaking mode could never be enabled to control the RTS line
The patches were made from the next-20141205 tag of the linux-next repository.
They were tested on a SAMA5Dx FPGA platform.
