This series adds support for Marvell berlin4ct pin-controller, allowing to configure the pin muxing from the device tree. This series applies on top of patches adding GPIO support for berlin4ct[1].

| Message-ID | <qanfI-6H6-25@gated-at.bofh.it> |
| In reply to | #1228419 |
Add the avio, soc, sm pinctrl nodes for Marvell berlin4ct SoC. This
patch also adds urt0 txd and rxd muxing setup in the dtsi because uart0
always use them to work, no other possibilities.

Please split the patch into two:
one adding the pinctrl nodes and
one adding the default pinmux to uart0 node.

pinctrl-names = "default", "default"; refers to pinctrl-0 and pinctrl-1
respectively. There is no pinctrl-1, so please remove the second
pinctrl-names element.

If you change the driver to generic function names ("uart0") this
boils down to a single
uart0_pmux: uart0-pmux {
groups = "SM_UART0_TXD", "SM_UART0_RXD";
function = "uart0";
};
pinmux node and the reference in uart0 node to
pinctrl-0 = <&uart0_pmux>;
pinctrl-names = "default";
