This driver allows I/O operations on the Samsung S2MPS11 PMIC,
which provides lots of LDO/BUCK outputs.

To enable it, update defconfig with:
- CONFIG_DM_PMIC_S2MPS11
and additional, if were not defined:
- CONFIG_CMD_PMIC
- CONFIG_ERRNO_STR

The binding info: doc/device-tree-bindings/pmic/s2mps11.txt

nit: I don't think this should have a DM_ prefix. Remember that all
the CONFIG_DM_... options are going to be removed one day. It is
intended to select the DM version of a subsystem. In your case you
only have a DM version of the driver, so just CONFIG_PMIC_S2MPS11
seems fine.

+
+Required properties:
+- compatible: "samsung,s2mps11-pmic"
+- reg = 0x66
+
+With those two properties, the pmic device can be used for read/write only.

+Example:
