This patch series add support for baudrates higher than 230400 on Marvell Armada 37xx boards. Changes in v7: * fixed lint errors in yaml binding file Changes in v6: * fixed yaml binding file and dts files 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.
