Subject: [PATCH v3 1/2] regulator: dt-bindings: Document TI TPS65185

Document the TPS65185. GPIO names are same as in the datasheet except for
the PWRUP pad which is described as "enable". That pin is optional because
the rising edge corresponds to setting one register bit and falling edge
to another register bit.

+description:
+  TPS65185 is a Power Management IC to provide Power for EPDs with one 3.3V
+  switch, 2 symmetric LDOs behind 2 DC/DC converters, and one unsymmetric
+  regulator for a compensation voltage.
