-Synaptics SoC Device Tree Bindings
-
-According to https://www.synaptics.com/company/news/conexant-marvell
-Synaptics has acquired the Multimedia Solutions Business of Marvell, so
-berlin SoCs are now Synaptics' SoCs now.
-
----------------------------------------------------------------
-
-Boards with a SoC of the Marvell Berlin family, e.g. Armada 1500
-shall have the following properties:
-
-* Required root node properties:
-compatible: must contain "marvell,berlin"
-
-In addition, the above compatible shall be extended with the specific
-SoC and board used. Currently known SoC compatibles are:
-    "marvell,berlin2"      for Marvell Armada 1500 (BG2, 88DE3100),
-    "marvell,berlin2cd"    for Marvell Armada 1500-mini (BG2CD, 88DE3005)
-    "marvell,berlin2ct"    for Marvell Armada ? (BG2CT, 88DE????)
-    "marvell,berlin2q"     for Marvell Armada 1500-pro (BG2Q, 88DE3114)
-    "marvell,berlin3"      for Marvell Armada ? (BG3, 88DE????)
-
-* Example:
-
-/ {
-	model = "Sony NSZ-GS7";
-	compatible = "sony,nsz-gs7", "marvell,berlin2", "marvell,berlin";
-
-	...
-}
-
-* Marvell Berlin CPU control bindings
-
-CPU control register allows various operations on CPUs, like resetting them
-independently.
-
-Required properties:
-- compatible: should be "marvell,berlin-cpu-ctrl"
-- reg: address and length of the register set
-
-Example:
-
-cpu-ctrl@f7dd0000 {
-	compatible = "marvell,berlin-cpu-ctrl";
-	reg = <0xf7dd0000 0x10000>;
-};
-
-* 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:
-	* the first and second values must be:
-		"simple-mfd", "syscon"
-- 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:
-	* the first and second values must be:
-		"simple-mfd", "syscon"
-- reg: address and length of the system control register set
-
-Example:
-
-chip: chip-control@ea0000 {
-	compatible = "simple-mfd", "syscon";
-	reg = <0xea0000 0x400>;
-
-	/* sub-device nodes */
-};
-
-sysctrl: system-controller@d000 {
-	compatible = "simple-mfd", "syscon";
-	reg = <0xd000 0x100>;
-
-	/* sub-device nodes */
-};
