Merge tag 'regulator-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This time around most of the changes are a lot of new drivers along
  with the standard set of fixes and cleanups (thanks again largely to
  Axel Lin).  We do have one nice new feature in the core which factors
  out the disappointingly tricky code around DT parsing, only a couple
  of drivers have been converted so far:

   - Factor out the code for parsing the standard bindings for a set of
     regulators out of DT, making the probe part of a lot of drivers
     simplier.
   - New drivers for Dialog DA9213, HiSilicon HI6420, Intersil
     ISL9305/H, Ricoh RN5T618, Rockchip RK808, Skyworks SKY81452,
     Silergy SYR82x, and Qualcomm RPM"

+Binding for Maxim MAX77802 regulators
+
+This is a part of device tree bindings of MAX77802 multi-function device.
+More information can be found in bindings/mfd/max77802.txt file.
+
+The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional node:
+- regulators : The regulators of max77802 have to be instantiated
+  under subnode named "regulators" using the following format.
+
+        regulator-name {
+                standard regulator constraints....
+        };
+        refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+The regulator node name should be initialized with a string to get matched
+with their hardware counterparts as follow. The valid names are:
+
+        -LDOn   :       for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
+                        and 32-35.
+                        example: LDO1, LDO2, LDO35.
+        -BUCKn  :       for BUCKs, where n can lie in range 1 to 10.
+                        example: BUCK1, BUCK5, BUCK10.
