Subject[PATCH v5 0/6] serial: mvebu-uart: Support for higher baudrates
Date
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 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.

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
