Merge tag 'mfd-3.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next

Pull MFD (multi-function device) updates from Samuel Ortiz:
 "For the 3.12 merge window we have one new driver for the DA9063 PMIC
  from Dialog Semiconductor.

  Besides that driver we also have:

   - Device tree support for the s2mps11 driver

   - More devm_* conversion for the pm8921, max89xx, menelaus, tps65010,
     wl1273 and pcf50633-adc drivers.

   - A conversion to threaded IRQ and IRQ domain for the twl6030 driver.

   - A fairly big update for the rtsx driver: Better power saving
     support, better vendor settings handling, and a few fixes.

   - Support for a couple more boards (COMe-bHL6 and COMe-cTH6) for the
     Kontron driver.

   - A conversion to the dev_get_platdata() API for all MFD drivers.

   - A removal of non-DT (legacy) support for the twl6040 driver.

   - A few fixes and additions (Mic detect level) to the wm5110 register
     tables.

   - Regmap support for the davinci_voicecodec driver.

   - The usual bunch of minor cleanups and janitorial fixes"

+* Samsung S2MPS11 Voltage and Current Regulator
+
+The Samsung S2MP211 is a multi-function device which includes voltage and
+current regulators, RTC, charger controller and other sub-blocks. It is
+interfaced to the host controller using a I2C interface. Each sub-block is
+addressed by the host system using different I2C slave address.
+
+Required properties:
+- compatible: Should be "samsung,s2mps11-pmic".
+- reg: Specifies the I2C slave address of the pmic block. It should be 0x66.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+  the interrupts from s2mps11 are delivered to.
+- interrupts: Interrupt specifiers for interrupt sources.
+
+Optional nodes:
+- clocks: s2mps11 provides three(AP/CP/BT) buffered 32.768 KHz outputs, so to
+  register these as clocks with common clock framework instantiate a sub-node
+  named "clocks". It uses the common clock binding documented in :
+  [Documentation/devicetree/bindings/clock/clock-bindings.txt]
+  - #clock-cells: should be 1.
+
+  - The following is the list of clocks generated by the controller. Each clock
+    is assigned an identifier and client nodes use this identifier to specify
+    the clock which they consume.
+    Clock               ID
+    ----------------------
+    32KhzAP		0
+    32KhzCP		1
+    32KhzBT		2
+
+- regulators: The regulators of s2mps11 that have to be instantiated should be
+included in a sub-node named 'regulators'. Regulator nodes included in this
+sub-node should be of the format as listed below.
+
+	regulator_name {
+		[standard regulator constraints....];
+	};
+
+ regulator-ramp-delay for BUCKs = [6250/12500/25000(default)/50000] uV/us
+
+ BUCK[2/3/4/6] supports disabling ramp delay on hardware, so explictly
+ regulator-ramp-delay = <0> can be used for them to disable ramp delay.
+ In absence of regulator-ramp-delay property, default ramp delay will be used.
+
+NOTE: Some BUCKs share the ramp rate setting i.e. same ramp value will be set
+for a particular group of BUCKs. So provide same regulator-ramp-delay<value>.
+Grouping of BUCKs sharing ramp rate setting is as follow : BUCK[1, 6],
+BUCK[3, 4], and BUCK[7, 8, 10]
+
+The regulator constraints inside the regulator nodes use the standard regulator
+bindings which are documented elsewhere.
+
+The following are the names of the regulators that the s2mps11 pmic block
+supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
+as per the datasheet of s2mps11.
+
+	- LDOn
+		  - valid values for n are 1 to 28
+		  - Example: LDO0, LD01, LDO28
+	- BUCKn
+		  - valid values for n are 1 to 9.
+		  - Example: BUCK1, BUCK2, BUCK9
+
+Example:
+
+	s2mps11_pmic@66 {
+		compatible = "samsung,s2mps11-pmic";
+		reg = <0x66>;
+
+		s2m_osc: clocks{
+			#clock-cells = 1;
+			clock-output-names = "xx", "yy", "zz";
+		};
+
+		regulators {
+			ldo1_reg: LDO1 {
+				regulator-name = "VDD_ABB_3.3V";
+				regulator-min-microvolt = <3300000>;
+				regulator-max-microvolt = <3300000>;

+				regulator-name = "VDD_ALIVE_1.1V";
+				regulator-min-microvolt = <1100000>;
+				regulator-max-microvolt = <1100000>;
+				regulator-always-on;
+			};

+			buck1_reg: BUCK1 {
+				regulator-name = "vdd_mif";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1350000>;
+				regulator-always-on;
