Hi, This series adds support for the armada-37xx extended UART port. The new capabilities of this IP compared to the standard port are the possibility to use DMA, it has bigger FIFOs (128 bytes instead of 32/64), it is possible to fill the FIFO byte-per-byte or 4 bytes at a time, it as RTC and CTS control, it supports transfer count for RX/TX with transfer finish status and finally it may achieve higher baudrates by the use of special dividers. Almost none of these extended features is implemented though. For now, the extended UART is just supported with the same features as the standard UART. This IP is present on the Armada 3720 SoC and is now enabled by the device tree related patches on the Armada-3720-DB. As adding the node to enable the second port on Armada-3720-ESPRESSObin could break existing users by changing the configuration of some pins on the main headers, only a side note is added on how to do it easily. - The driver patches should go through Greg KH. - The DT patches should go through the mvebu maintainers. - We would also like the DT binding documentation update to go through the mvebu maintainers, as it conflicts with another DT change.
