Subject: [PATCH 05/17] dt-bindings: mfd: samsung,s2mps11: add s2mpg11-pmic

The Samsung S2MPG11 PMIC is similar to the existing S2MPG10 PMIC
supported by this binding.

It is a Power Management IC for mobile applications with buck
converters, various LDOs, and power meters and typically complements an
S2MPG10 PMIC in a main/sub configuration as the sub-PMIC.

Like S2MPG10, 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.

Add the PMIC, the regulators node, and the supply inputs of the
regulator rails, with the supply names matching the datasheet.

Note: S2MPG11 is typically used as the sub-PMIC together with an
S2MPG10 PMIC in a main/sub configuration, hence the datasheet and the
binding both suffix the supplies with an 's'.
