This is still not making any sense. The quality of regulation and
output voltage are essentially orthogonal, and obviously there's a
specific API for bypass which is something different again to both
mode and output voltage selection.

Do you recommend adding API's (similar to bypass) for BOOST and SWITCH?

No. A boost regulator is still a voltage regulator, it just happens to
raise rather than lower the voltage but it's otherwise a normal
regulator. I'm not sure what you mean by "SWITCH" - from the name it'd
just be a bypass?

Copy-pasting Laxman's explanation


Palma have SMPS10 regulator which can generate two voltage level 3.75 and 5V.
This SMPS10 has the two outputs OUT1 and OUT2 and having one input IN1.

SMPS10-OUT2 is always connected to SMPS10-IN1 via following logic:
- Through parasitic diode (no sw control)
- In bypass mode (bit configuration is there to enable/disable Bypass)
- In Boost mode (bit configuration is there to enable/disable Boost mode)

SMPS10-OUT1 is connected to the SMPS10-OUT2 pin through Switch (SW control for enabling/disabling this switch).
