This patch series add support for baudrates higher than 230400 on Marvell Armada 37xx boards. Please review these patches as they touch both Device Tree bindings and mvebu-uart.c driver.
Stephen, is this patch series OK now? Or is there any other issue?
Changes in v5:
* fixed yaml binding file
Changes in v4:
* converted armada3700-uart-clock documentation to YAML
* split documentation changes into two commits:
- first which adds clock documentation
- second which updates UART documentation
Changes in v3:
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.

math64: New DIV_U64_ROUND_CLOSEST helper
serial: mvebu-uart: implement UART clock driver for configuring UART
base clock
dt-bindings: mvebu-uart: document DT bindings for
marvell,armada-3700-uart-clock
dt-bindings: mvebu-uart: update information about UART clock
arm64: dts: marvell: armada-37xx: add device node for UART clock and
use it
