+ANATOP REGULATOR
+
+Anatop is an integrated regulator inside i.MX6 SoC.
+
+Required properties:
+- compatible:		Must be "fsl,anatop-regulator".
+- regulator-name:	Name of the regulator
+- anatop-reg-offset:	u32 value representing the anatop MFD register offset.
+- anatop-vol-bit-shift:	u32 value representing the bit shift for the register.
+- anatop-vol-bit-width:	u32 value representing the number of bits used in the
+  			register.
+- anatop-min-bit-val:	u32 value representing the minimum value of this
+  			register.
+- anatop-min-voltage:	u32 value representing the minimum voltage of this
+  			regulator.
+- anatop-max-voltage:	u32 value representing the maximum voltage of this
+  			regulator.
+
+Optional properties:
+- anatop-delay-reg-offset: u32 value representing the anatop MFD step time
+  			   register offset.
+- anatop-delay-bit-shift: u32 value representing the bit shift for the step
+  			  time register.
+- anatop-delay-bit-width: u32 value representing the number of bits used in
+  			  the step time register.
+- anatop-enable-bit:	  u32 value representing regulator enable bit offset.
+- vin-supply:		  input supply phandle.

+GPIO-based Sysinfo device
+
+This binding describes several GPIOs which specify a board revision. Each GPIO
+forms a digit in a ternary revision number. This revision is then mapped to a
+name using the revisions and names properties.
+
+Each GPIO may be floating, pulled-up, or pulled-down, mapping to digits 2, 1,
+and 0, respectively. The first GPIO forms the least-significant digit of the
+revision. For example, consider the property
+
+	gpios = <&gpio 0>, <&gpio 1>, <&gpio 2>;
+
+If GPIO 0 is pulled-up, GPIO 1 is pulled-down, and GPIO 2 is floating, then the
+revision would be
+
+	0t201 = 2*9 + 0*3 + 1*3 = 19
+
+If instead GPIO 0 is floating, GPIO 1 is pulled-up, and GPIO 2 is pulled-down,
+then the revision would be
+
+	0t012 = 0*9 + 1*3 + 2*1 = 5
+
+Required properties:
+- compatible: should be "gpio-sysinfo".
+- gpios: should be a list of gpios forming the revision number,
+  least-significant-digit first
+- revisions: a list of known revisions; any revisions not present will have the
+  name "unknown"
+- names: the name of each revision in revisions
+
+Example:
+sysinfo {
+	compatible = "gpio-sysinfo";
+	gpios = <&gpio_a 15>, <&gpio_a 16>, <&gpio_a 17>;
+	revisions = <19>, <5>;
+	names = "rev_a", "foo";
+};

+=============
+
+Synopsis
+--------
+
+::
+
+    reset [-w]
+
+Description
+-----------
+
+Perform reset of the CPU. By default does COLD reset, which resets CPU,
+DDR and peripherals, on some boards also resets external PMIC.
+
+-w
+    Do warm WARM, reset CPU but keep peripheral/DDR/PMIC active.
+
+
+Return value
+------------
+
+The return value $? is always set to 0 (true).
