dt-bindings: mfd: samsung,s2mps11: add s2mpg10
The Samsung S2MPG10 PMIC is similar to the existing PMICs supported by
this binding.
It is a Power Management IC for mobile applications with buck
converters, various LDOs, power meters, RTC, clock outputs, and
additional GPIOs interfaces.
Unlike other Samsung PMICs, communication is not via I2C, but via the
Samsung ACPM firmware, it therefore doesn't need a 'reg' property but
needs to be a child of the ACPM firmware node instead.
S2MPG10 can also act as a system power controller allowing
implementation of a true cold-reset of the system.
Support for the other components like regulators and power meters will
be added in subsequent future patches.
