Hi,
This is a resend of the Allwinner D1 LDO driver series, separated by
subsystem. This part contains just the regulator driver bits. The sunxi
SRAM binding part will be sent out after the merge window due to a
conflict in next.
Original cover letter:
This series adds the binding and driver for one of the two pairs of LDOs
inside the Allwinner D1 SoC. I am splitting up the two pairs of LDOs to
unblock merging the SoC devicetree; the analog LDOs depend on the audio
codec binding, but they are not required to boot.
A binding and driver change is required for the SRAM controller, to
accept the regulators device as its child node.
The example for the regulator device binding is in SRAM controller
binding document, per Rob's request to keep MFD examples in one place.
Because of this, at least the first 3 patches need to be taken together
through the regulator tree, though it should be fine to merge the whole
series that way.
Changes in v5:
- Correct the voltage calculation for the non-linearity around 1.6 V.
Changes in v4:
- Fix the order of the maintainer/description sections
- Replace unevaluatedProperties with "additionalProperties: false"
- Drop the analog LDOs until the codec binding is ready
- Drop the analog LDOs until the codec binding is ready
- Remove unevaluatedProperties from regulators schema reference
- Check the compatible string instead of the node name
Changes in v3:
- Add "reg" property to bindings
- Add "unevaluatedProperties: true" to regulator nodes
- Minor changes to regulator node name patterns
- Remove system-ldos example (now added in the parent binding)
- Adjust control flow in sun20i_regulator_get_regmap() for clarity
- Require the regulators node to have a unit address
- Reference the regulator schema from the SRAM controller schema
- Move the system LDOs example to the SRAM controller schema
- Reorder the patches so the example passes validation
Changes in v2:
- Remove syscon property from bindings
- Update binding examples to fix warnings and provide context
- Use decimal numbers for .n_voltages instead of field widths
- Get the regmap from the parent device instead of a property/phandle

The Allwinner D1 SoC contains two pairs of in-package LDOs. The pair of
"system" LDOs is for general purpose use. LDOA generally powers the
board's 1.8 V rail. LDOB powers the in-package DRAM, where applicable.

D1 contains two pairs of LDOs, "analog" LDOs and "system" LDOs. They are
similar and can share a driver, but only the system LDOs have a DT
binding defined so far.
The system LDOs have a single linear range. The voltage step is not an
integer, so a custom .list_voltage is needed to get the rounding right.

This says that the driver depends on the SRAM change which isn't getting
merged this time round?

The SRAM driver change was already merged. The regulator DT binding doesn't
depend on the SRAM binding change; it's the other way around: the SRAM
binding change adds a reference to the new regulator binding.
Hope that explains things.

Looks like the patch was from when of_device.h still included of.h.
I'll send a new version shortly.

Thanks!
[1/2] regulator: dt-bindings: Add Allwinner D1 system LDOs
commit: 622bab1884847fcf3f9bfdf1d534fac3a5fe859f

commit: 4e70b26c873dfff317039458a6ea66314bbdce99
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
