Well, this patch is about moving the pinctrl nodes to the common SoC dtsi. The next 6 patches are about setting the default pinctrl property.

Ok, I see. Well, strictly speaking the setting node itself is always valid, no matter if the board uses it. So that is why I first moved them into kirkwood.dtsi and did set the pinctrl-0 property in the later patches, e.g. commit message of Patch 9 reads:
""" Most boards use the default UART0/1 pinctrl setting without RTS/CTS. Add the pinctrl setting to the toplevel SoC UART nodes and put a note in front of the corresponding pinctrl node to overwrite the setting on board level. Currently, both boards using a different UART pinctrl setting (Openblocks A6, A7) already overwrite the pinctrl node. """
But I can, of course, reword this commit message.
