regulator: Drop obsolete dependencies on COMPILE_TEST

2022-11-24T16:30:19+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

As a minor optimization, this also lets us drop several occurrences of
of_match_ptr(), __maybe_unused and some ifdef guarding, as we now know
what all of this will resolve to, we might as well save cpp some work.

regulator: mp886x: Convert to use regulator_set_ramp_delay_regmap

2021-05-25T15:45:09+00:00

Use regulator_set_ramp_delay_regmap instead of open-coded.

regulator: mp886x: use "mps,switch-frequency-hz"

2020-08-24T13:17:53+00:00

As Rob suggested, use the "mps,switch-frequency-hz" instead of the
"mps,switch-frequency" for switch frequency. Fortunately, the switch
frequency support isn't released, so we can modify it now without
any concern.

regulator: mp886x: implement set_ramp_delay

2020-07-31T18:53:35+00:00

Implement the .set_ramp_delay for MP8867 and MP8869. MP8867 and MP8869
could share the implementation, the only difference is the slew_rates
array.

regulator: mp886x: use .probe_new

2020-07-02T15:45:46+00:00

Use the new .probe_new for mp886x. It does not use the const
struct i2c_device_id * argument, so convert it to utilise the
simplified i2c driver registration.

regulator: mp886x: add MP8867 support

2020-03-16T18:27:35+00:00

MP8867 is an I2C-controlled adjustable voltage regulator made by
Monolithic Power Systems. The difference between MP8867 and MP8869
are:
1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of
MP8867 is determined by the I2C control.
2.For MP8867, when setting voltage, if the step is within 5, we
need to manually set the GO BIT to 0.

regulator: add support for MP8869 regulator

2020-03-16T18:27:34+00:00

The MP8869 from Monolithic Power Systems is a single output DC/DC
converter. The voltage can be controlled via I2C.
