This patch series fixes mvebu-uart driver used on Marvell Armada 37xx
boards and add support for baudrates higher than 230400.
Pali Rohár (10):
serial: mvebu-uart: fix calculation of clock divisor
serial: mvebu-uart: do not allow changing baudrate when uartclk is not
available
serial: mvebu-uart: correctly calculate minimal possible baudrate
dt-bindings: mvebu-uart: fix documentation
arm64: dts: marvell: armada-37xx: Fix reg for standard variant of UART
serial: mvebu-uart: remove unused member nb from struct mvebu_uart
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
arm64: dts: marvell: armada-37xx: add device node for UART clock and
use it
