+* Samsung S2MPS11, S2MPS13, S2MPS14 and S2MPU02 Voltage and Current Regulator
The Samsung S2MPS11 is a multi-function device which includes voltage and
current regulators, RTC, charger controller and other sub-blocks. It is
addressed by the host system using different I2C slave addresses.
Required properties:
-- compatible: Should be "samsung,s2mps11-pmic" or "samsung,s2mps14-pmic"
- or "samsung,s2mpu02-pmic".
+- compatible: Should be "samsung,s2mps11-pmic" or "samsung,s2mps13-pmic"
+ or "samsung,s2mps14-pmic" or "samsung,s2mpu02-pmic".
- reg: Specifies the I2C slave address of the pmic block. It should be 0x66.
Optional properties:
- interrupts: Interrupt specifiers for interrupt sources.
Optional nodes:
-- clocks: s2mps11 and s5m8767 provide 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 :
