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.

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.

Pali Rohár (6):
  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
  serial: mvebu-uart: implement support for baudrates higher than 230400
