Subject: [PATCH RFC 0/7] regulator: new APIs for voltage reference supplies
Date: Wed, 27 Mar 2024 18:18:49 -0500 [thread overview]
Message-ID: <20240327-regulator-get-enable-get-votlage-v1-0-5f4517faa059@baylibre.com> (raw)
In the IIO subsystem, we noticed a pattern in many drivers where we need
to get, enable and get the voltage of a supply that provides a reference
voltage. In these cases, we only need the voltage and not a handle to
the regulator. Another common pattern is for chips to have an internal
reference voltage that is used when an external reference is not
available. There are also a few drivers outside of IIO that do the same.
So we would like to propose a couple of new regulator consumer APIs to
handle these specific cases to avoid repeating the same boilerplate code
in multiple drivers.
As an example of how these functions are used, I have included a few
patches to consumer drivers. But to avoid a giant patch bomb, I have
omitted the iio/adc and iio/dac patches I have prepared from this
series. I will send those separately but these will add 12 more users
of devm_regulator_get_enable_get_voltage() and 24 more users of
devm_regulator_get_optional_enable_get_voltage(). In total, this will
eliminate nearly 1000 lines of similar code.
