Merge Linus master into drm-next

The merge is clean, but the arm build fails afterwards,
due to API changes in the regulator tree.

I've included the patch into the merge to fix the build.

+- compatible: "x-powers,axp202" or "x-powers,axp209"

+- interrupt-parent: The parent interrupt controller
+- interrupts: SoC NMI / GPIO interrupt connected to the PMIC's IRQ pin
+- interrupt-controller: axp20x has its own internal IRQs
+- #interrupt-cells: Should be set to 1
+
+Optional properties:
+- x-powers,dcdc-freq: defines the work frequency of DC-DC in KHz
+		      (range: 750-1875). Default: 1.5MHz
+- <input>-supply: a phandle to the regulator supply node. May be omitted if
+		  inputs are unregulated, such as using the IPSOUT output
+		  from the PMIC.
+
+- regulators: A node that houses a sub-node for each regulator. Regulators
+	      not used but preferred to be managed by the OS should be
+	      listed as well.
+	      See Documentation/devicetree/bindings/regulator/regulator.txt
+	      for more information on standard regulator bindings.
+
+Optional properties for DCDC regulators:
+- x-powers,dcdc-workmode: 1 for PWM mode, 0 for AUTO (PWM/PFM) mode
+			  Default: Current hardware setting
+			  The DCDC regulators work in a mixed PWM/PFM mode,
+			  using PFM under light loads and switching to PWM
+			  for heavier loads. Forcing PWM mode trades efficiency
+			  under light loads for lower output noise. This
+			  probably makes sense for HiFi audio related
+			  applications that aren't battery constrained.
