[PATCH v1 1/7] regulator: dt-bindings: add documentation for s2mps16-pmic regulators
Posted by Ivaylo Ivanov 2 weeks, 4 days ago 
The S2MPS16 is a PMIC found in exynos8890 devices, which controls voltage
regulators - 38 LDOs, of which 11 are used for CP, and 11 BUCKs, of which
1 is used for CP. Provide documentation for devicetree definitions,
regulator naming patterns, etc.

What does unimplemented mean? In some driver? If so, that's specific to 
a driver and not relevant to the binding.

Also, drop 'documentation for' in the subject.
