[PATCH 00/14] regulator: axp20x: Stop AXP209 from crashing when enabling LDO3

[Priit Laes]

This series implements voltage ramping for AXP209 DCDC2 and LDO3
regulators and software based soft-start for AXP209 LDO3 regulator.

Both features are needed to work around a PMIC shutdown when
toggling LDO3 on certain boards with high capacitance on the
LDO3 output.

Similar features (or workarounds) have been also implemented
on u-boot side [1].

Also included in this series are various magic constant cleanups
and also fix for core regulator framework, where 'always-enabled'
constraint overrides the 'soft-start' and 'ramp-delay' features.

[1] https://lists.denx.de/pipermail/u-boot/2018-November/348612.html

[PATCH 01/14] regulator: axp20x: use defines for masks

[Priit Laes]

From: Olliver Schinagl <oliver@schinagl.nl>

The AXP20X driver currently has several masks defined throughout the
code. Use nice defines to make them clean and more descriptive.

Additionally include bitops.h, which was missing before, and sort
headers.

[PATCH 02/14] regulator: axp20x: name voltage ramping define properly

[Priit Laes]

From: Olliver Schinagl <oliver@schinagl.nl>

The current axp20x names the ramping register 'scal' which probably
means scaling. Since the register really has nothing to do with
scaling, but really is the voltage ramp we rename it appropriately.

[PATCH 03/14] regulator: core: enable power when setting up constraints

[Priit Laes]

From: Olliver Schinagl <oliver@schinagl.nl>

When a regulator is marked as always on, it is enabled early on, when
checking and setting up constraints. It makes the assumption that the
bootloader properly initialized the regulator, and just in case enables
the regulator anyway.

Some constraints however currently get missed, such as the soft-start
and ramp-delay. This causes the regulator to be enabled, without the
soft-start and ramp-delay being applied, which in turn can cause
high-currents or other start-up problems.

By moving the always-enabled constraints later in the constraints check,
we can at least ensure all constraints for the regulator are followed.

[PATCH 04/14] regulator: axp20x: add support for set_ramp_delay for AXP209

[Priit Laes]

From: Olliver Schinagl <oliver@schinagl.nl>

The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3.

This patch adds preliminary support for the regulator-ramp-delay property
for these 2 regulators. Note that the voltage ramp only works when
regulator is already enabled. E.g. when going from say 0.7 V to 3.6 V.

When turning on the regulator, no voltage ramp is performed in hardware.

What this means, is that if the bootloader brings up the voltage at 0.7 V,
the ramp delay property is properly applied. If however, the bootloader
leaves the power off, no ramp delay is applied when the power is
enabled by the regulator framework.

[PATCH 06/14] regulator: axp20x: add software based soft_start for AXP209 LDO3

[Priit Laes]

From: Olliver Schinagl <oliver@schinagl.nl>

In the past, there have been words on various lists that if LDO3 is
disabled in u-boot, but enabled in the DTS, the axp209 driver would
fail to continue/hang. Several enable/disable patches have been
issues to devicetree's in both the kernel and u-boot to address
this issue.

What really happened however, was that the AXP209 shuts down without
a notice and without setting an interrupt. This is caused when LDO3
gets overloaded, for example with large capacitors on the LDO3 output.

Normally, we would expect that AXP209 would source 200 mA as per
datasheet and set and trigger an interrupt when being overloaded.
For some reason however, this does not happen.

As a work-around, we use the soft-start constraint of the regulator
node to first bring up the LDO3 to the lowest possible voltage and
then enable the LDO. After that, we can set the requested voltage
as usual.

Combining this setting with the regulator-ramp-delay allows LDO3 to
enable voltage slowly and staggered, potentially reducing overall
inrush current.

[PATCH 07/14] dt-bindings: mfd: axp20x: Add software based soft_start for AXP209 LDO3

As a work-around, implement software-based 'regulator-soft-start'

After that, we can set the requested voltage as usual.

[PATCH 08/14] regulator: dts: enable soft-start and ramp delay for the OLinuXino Lime2

[Priit Laes]

From: Olliver Schinagl <oliver@schinagl.nl>

The OLinuXino Lime2 has a big capacitor on its LDO3 output. It is
actually too large, causing the PMIC to shutdown when toggling the LDO3.

By enabling soft-start and ramp delay we increase the time for the
capacitor to charge lowering the current drain on the power regulator.

[PATCH 09/14] regulator: dts: add full voltage range to LDO4 on the Lime2

[Priit Laes]

From: Olliver Schinagl <oliver@schinagl.nl>

With commit b43776d65a33b46092 ("ARM: dts: sunxi: Use axp209.dtsi for
Olinuxino Lime2") we force them an arbitrary 2.8 volts. Granted, for
LDO3 this may be less arbitrary, but for LDO4 this is just wrong.

In the defense of LDO3, LDO3 is the regulator that feeds port bank E,
which has no other purpose then a CSI/TS interface, however the case
may still be, that the connected IO may be just as well be 3.3 volts.
The big misnomer is however, that the schematic names GPIO-2 pin4
LDO3_2.8V, rather then VDD-CSI0 or similar.

This is much worse for LDO4 however, which is not referenced on any
pin, is now set to 2.8 volts, but port bank G can also support various
other peripherals such as UARTS etc.

By having 2.8 volts however for LDO4, we thus now have peripherals that
no longer function properly all of the time.

Ideally, we want to set a supply voltage for each port bank, but the
monolithic nature of the sunxi pinctroller currently prevents this and
as such, the board should at least configure the LDO4 with the proper
ranges.

Until we can set the consumer at the port bank level, a child
device-tree has to do something like:

&reg_ldo4 {
    regulator-min-microvolt = <3300000>;
    regulator-max-microvolt = <3300000>;
};

While doing this the same way results in the same solution currently,
we force the hack into the final devicetree rather then having it wrong
at the board level.

In general you want to run regulators at the lowest voltage you can,
this tends to reduce power consumption.

This is obviously broken even according to your analysis above - if you
have consumers for which 2.8V is too low allowing other consumers to set
even lower voltages is not going to help as soon as they start doing
that.

This is a generic property, there is no need to document it in each
device binding.

This is some pretty generic code, and could be useful to some other
users. I guess a generic function would be better for this.

As we discussed on the U-Boot ML already, this shouldn't be made
always-on but tied to the consumer device (the pinctrl one) instead.

Please help fix up the subject. Should read

"ARM: dts: sun7i: set proper lradc vref on OLinuXino Lime2"

or

"ARM: dts: sun7i: olinoxino-lime2: set proper lradc vref"

It's not unwelcome here though.

Yes, makes sense. Although, should we then also distinguish between
regulators which support soft-start in hardware and devices which emulate
it by delay, like in this case?

Quick test (after applying this: http://code.bulix.org/w01xab-518044?raw )
results in failure:

And I cannot actually see the link between pinctrl and ldo4. There's currently only this link:

sun4i-pinctrl 1c20800.pinctrl: Linked as a consumer to regulator.0

$ cat /sys/class/regulator/regulator.0/name

Drivers should not be emulating soft start, if they need a ramp delay
they should set that in their descriptor and let the framework do it.
