+
+* Marvell Berlin2 chip control binding
+
+Marvell Berlin SoCs have a chip control register set providing several
+individual registers dealing with pinmux, padmux, clock, reset, and secondary
+CPU boot address. Unfortunately, the individual registers are spread among the
+chip control registers, so there should be a single DT node only providing the
+different functions which are described below.
+
+Required properties:
+- compatible: shall be one of
+ "marvell,berlin2-chip-ctrl" for BG2
+ "marvell,berlin2cd-chip-ctrl" for BG2CD
+ "marvell,berlin2q-chip-ctrl" for BG2Q
+- reg: address and length of following register sets for
+ BG2/BG2CD: chip control register set
+ BG2Q: chip control register set and cpu pll registers
+
+* Marvell Berlin2 system control binding
+
+Marvell Berlin SoCs have a system control register set providing several
+individual registers dealing with pinmux, padmux, and reset.
+
+Required properties:
+- compatible: should be one of
+ "marvell,berlin2-system-ctrl" for BG2
+ "marvell,berlin2cd-system-ctrl" for BG2CD
+ "marvell,berlin2q-system-ctrl" for BG2Q
+- reg: address and length of the system control register set
+
+* Clock provider binding
+
+As clock related registers are spread among the chip control registers, the
+chip control node also provides the clocks. Marvell Berlin2 (BG2, BG2CD, BG2Q)
+SoCs share the same IP for PLLs and clocks, with some minor differences in
+features and register layout.
+
+Required properties:
+- #clock-cells: shall be set to 1
+- clocks: clock specifiers referencing the core clock input clocks
+- clock-names: array of strings describing the input clock specifiers above.
+ Allowed clock-names for the reference clocks are
+ "refclk" for the SoCs osciallator input on all SoCs,
+ and SoC-specific input clocks for
+ BG2/BG2CD: "video_ext0" for the external video clock input
+
+Clocks provided by core clocks shall be referenced by a clock specifier
+indexing one of the provided clocks. Refer to dt-bindings/clock/berlin<soc>.h
+for the corresponding index mapping.
+
+* Pin controller binding
+
+Pin control registers are part of both register sets, chip control and system
+control. The pins controlled are organized in groups, so no actual pin
+information is needed.
+
+A pin-controller node should contain subnodes representing the pin group
+configurations, one per function. Each subnode has the group name and the muxing
+function used.
+
+Be aware the Marvell Berlin datasheets use the keyword 'mode' for what is called
+a 'function' in the pin-controller subsystem.
+
+Required subnode-properties:
+- groups: a list of strings describing the group names.
+- function: a string describing the function used to mux the groups.
+
+Example:
+
+chip: chip-control@ea0000 {
+ compatible = "marvell,berlin2-chip-ctrl";
+ #clock-cells = <1>;
+ reg = <0xea0000 0x400>;
+ clocks = <&refclk>, <&externaldev 0>;
+ clock-names = "refclk", "video_ext0";
+
+ spi1_pmux: spi1-pmux {
+ groups = "G0";
+ function = "spi1";
+ };
+};
+
+sysctrl: system-controller@d000 {
+ compatible = "marvell,berlin2-system-ctrl";
+ reg = <0xd000 0x100>;
+
+ uart0_pmux: uart0-pmux {
+ groups = "GSM4";
+ function = "uart0";
+ };
+
+ uart1_pmux: uart1-pmux {
+ groups = "GSM5";
+ function = "uart1";
+ };
+
+ uart2_pmux: uart2-pmux {
+ groups = "GSM3";
+ function = "uart2";
