regulator: max8973: Finalize switch to GPIO descriptors

2024-02-26T13:46:33+00:00

The dvs gpio was still using a legacy number passed from the
platform data. There are no in-tree users of the platform data
so just switch it to a gpio descriptor and obtain it in probe(),
the device tree users will work just as fine with this.

Drop the entirely unused enable_gpio from the platform data
as well. The device tree bindings mentions this but the driver
does not look for it and makes no use of it: it should probably
be implemented properly in a separate patch.

regulator: Reuse LINEAR_RANGE() in REGULATOR_LINEAR_RANGE()

2023-12-19T16:15:14+00:00

REGULATOR_LINEAR_RANGE() repeats what LINEAR_RANGE() provides.
Deduplicate the former by using the latter. No functional change
intended.

regulator: event: Add regulator netlink event support

2023-12-06T13:14:54+00:00

This commit introduces netlink event support to the regulator subsystem.

Changes:
- Introduce event.c and regnl.h for netlink event handling.
- Implement reg_generate_netlink_event to broadcast regulator events.
- Update Makefile to include the new event.c file.

regulator: Implement uv_survival_time for handling under-voltage events

2023-11-13T01:26:28+00:00

Add 'uv_survival_time' field to regulation_constraints for specifying
survival time post critical under-voltage event. Update the regulator
notifier call chain and Device Tree property parsing to use this new
field, allowing a configurable timeout before emergency shutdown.

regulator: mt6358: Add missing regulators for MT6366

2023-10-02T18:43:49+00:00

When support for the MT6366 PMIC regulators was added, it was assumed
that it had the same functionality as MT6358. In reality there are
differences. A few regulators have different ranges, or were renamed
and repurposed, or removed altogether.

Add the 3 regulators that were missing from the original submission.
These are added for completeness. VSRAM_CORE is not used in existing
projects. VM18 and VMDDR feed DRAM related consumers, and are not used
in-kernel.

regulator: Use bitfield values for range selectors

2023-07-25T11:14:27+00:00

Right now the regulator helpers expect raw register values for the range
selectors. This is different from the voltage selectors, which are
normalized as bitfield values. This leads to a bit of confusion. Also,
raw values are harder to copy from datasheets or match up with them,
as datasheets will typically have bitfield values.

Make the helpers expect bitfield values, and convert existing users. The
field in regulator_desc is renamed to |linear_range_selectors_bitfield|.
This is intended to cause drivers added in the same merge window and
out-of-tree drivers using the incorrect variable and values to break,
preventing incorrect values being used on actual hardware and potentially
producing magic smoke.

Also include bitops.h explicitly for ffs(), and reorder the header include
statements. While at it, also replace module.h with export.h, since the
only use is EXPORT_SYMBOL_GPL.

Merge tag 'regulator-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

2023-06-28T20:32:47+00:00

Pull regulator updates from Mark Brown:
 "This release is almost all drivers, there's some small improvements in
  the core but otherwise everything is updates to drivers, mostly the
  addition of new ones.

  There's also a bunch of changes pulled in from the MFD subsystem as
  dependencies, Rockchip and TI core MFD code that the regulator drivers
  depend on.

  I've also yet again managed to put a SPI commit in the regulator tree,
  I don't know what it is about those two trees (this for
  spi-geni-qcom).

  Summary:

   - Support for Renesas RAA215300, Rockchip RK808, Texas Instruments
     TPS6594 and TPS6287x, and X-Powers AXP15060 and AXP313a"

regulator: pca9450: Fix LDO3OUT and LDO4OUT MASK

2023-06-19T14:13:17+00:00

L3_OUT and L4_OUT Bit fields range from Bit 0:4 and thus the
mask should be 0x1F instead of 0x0F.
