Merge tag 'regulator-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is an extremely quiet release for the regulator API, we've got a
  small set of bug fixes and minor feature enhancements for drivers plus
  a couple of more visible changes:

   - add support for ramp times in regulators that don't use selectors.

   - new driver for LTC3676"

+Linear Technology LTC3676 8-output regulators
+
+Required properties:
+- compatible: "lltc,ltc3676"
+- reg: I2C slave address
+
+Required child node:
+- regulators: Contains eight regulator child nodes sw1, sw2, sw3, sw4,
+  ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as
+  documented in Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Each regulator is defined using the standard binding for regulators. The
+nodes for sw1, sw2, sw3, sw4, ldo1, ldo2 and ldo4 additionally need to specify
+the resistor values of their external feedback voltage dividers:
+
+Required properties (not on ldo3):
+- lltc,fb-voltage-divider: An array of two integers containing the resistor
+  values R1 and R2 of the feedback voltage divider in ohms.
+
+Regulators sw1, sw2, sw3, sw4 can regulate the feedback reference from:
+412.5mV to 800mV in 12.5 mV steps. The output voltage thus ranges between
+0.4125 * (1 + R1/R2) V and 0.8 * (1 + R1/R2) V.
+
+Regulators ldo1, ldo2, and ldo4 have a fixed 0.725 V reference and thus output
+0.725 * (1 + R1/R2) V. The ldo3 regulator is fixed to 1.8 V.  The ldo1 standby
+regulator can not be disabled and thus should have the regulator-always-on
+property set.
