      1* Pin-controller driver for the Marvell Berlin SoCs
      2
      3Pin control registers are part of both chip controller and system
      4controller register sets. Pin controller nodes should be a sub-node of
      5either the chip controller or system controller node. The pins
      6controlled are organized in groups, so no actual pin information is
      7needed.
      8
      9A pin-controller node should contain subnodes representing the pin group
     10configurations, one per function. Each subnode has the group name and
     11the muxing function used.
     12
     13Be aware the Marvell Berlin datasheets use the keyword 'mode' for what
     14is called a 'function' in the pin-controller subsystem.
     15
     16Required properties:
     17- compatible: should be one of:
     18	"marvell,berlin2-soc-pinctrl",
     19	"marvell,berlin2-system-pinctrl",
     20	"marvell,berlin2cd-soc-pinctrl",
     21	"marvell,berlin2cd-system-pinctrl",
     22	"marvell,berlin2q-soc-pinctrl",
     23	"marvell,berlin2q-system-pinctrl",
     24	"marvell,berlin4ct-avio-pinctrl",
     25	"marvell,berlin4ct-soc-pinctrl",
     26	"marvell,berlin4ct-system-pinctrl",
     27	"syna,as370-soc-pinctrl"
     28
     29Required subnode-properties:
     30- groups: a list of strings describing the group names.
     31- function: a string describing the function used to mux the groups.
     32
     33Example:
     34
     35sys_pinctrl: pin-controller {
     36	compatible = "marvell,berlin2q-system-pinctrl";
     37
     38	uart0_pmux: uart0-pmux {
     39		groups = "GSM12";
     40		function = "uart0";
     41	};
     42};
     43
     44&uart0 {
     45	pinctrl-0 = <&uart0_pmux>;
     46	pinctrl-names = "default";
     47};
