Subject: [PATCH] regulator: s2mps11: add support for S2MPS15 regulators
The S2MPS15 PMIC is similar in functionality to S2MPS11/14 PMIC. It contains
27 LDO and 10 Buck regulators and allows programming these regulators via a
I2C interface. This patch adds initial support for LDO/Buck regulators of
S2MPS15 PMIC.
