For the 3.12 merge window we have one new driver for the DA9063 PMIC

Browse Source 
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";
};
