Subject: [PATCH v4 7/7] ARM: dts: berlin: add the pinctrl node and muxing setup for uarts
From: Antoine Tenart <antoine.tenart@...e-electrons.com>
Add pinctrl bindings and system control nodes to what we currently know
about Berlin SoCs. Where available, also set default pinctrl property
for uarts, when there is only one pinmux option for it.
