regulator: mp886x: Fix ID table driver_data

2025-06-30T15:06:40+00:00

Currently, the driver_data of the i2c ID table is wrong, so it won't work if any mp886x user makes use of the ID table. Fortunately, there's no such user in upstream source code, we can fix the issue by using different ID table entry for mp8867 and mp8869.

regulator: mp886x: Make similar OF and ID table

2023-09-11T00:31:26+00:00

Make similar OF and ID table to extend support for ID match using i2c_match_data(). Currently it works only for OF match tables as the driver_data is wrong for ID match.

regulator: Explicitly include correct DT includes

2023-07-14T19:52:54+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

regulator: Switch i2c drivers back to use .probe()

2023-05-07T23:50:11+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 5.4 and 5.10

2023-03-20T13:11:28+00:00

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14") but changes regulators didn't exist in Linux 5.4 but did exist in Linux 5.10.

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: 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.
