This patch series add support for baudrates higher than 230400 on Marvell Armada 37xx boards. This new version v3 is rebased on top of Linus master branch and all already applied patches were dropped. There are no changes in patches itself since v2. Please review these patches as they touch both Device Tree bindings and mvebu-uart.c driver.
