[PATCH v5 0/8] mfd: AXP20x: Add support for AXP202 and AXP209

[Carlo Caione]

AXP209 and AXP202 are the PMUs (Power Management Unit) used by A10, A13
and A20 SoCs and developed by X-Powers, a sister company of Allwinner.
AXP20x comprises an adaptive USB-Compatible PWM charger, 2 BUCK DC-DC
converters, 5 LDOs, multiple 12-bit ADCs of voltage, current and temperature
as well as 4 configurable GPIOs. 

This set of patches introduces the core driver and support for two different
subsystems:
	- Regulators
	- PEK (Power Enable Key)

Changes since v1:

	- Added a new standalone patch for defconfig

	- MFD core:
	  * Removed axp,system-power-controller property

	- Bindings documentation:
	  * Corrected description for dcdc-workmode property
	  * Removed unused axp20x-pek compatible

	- Input misc PEK driver:
	  * Fixed seconds in lower case

	- Regulators subsystem:
	  * Fixed axp20x_set_suspend_voltage()
	  * Switched to using multi-bit control for regulators
	  * When "regulators" node is not found driver doesn't quit
	  * Driver is now using devm_regulator_register()
	  * Added module_platform_driver() instead of subsys_initcall()

	- DT:
	  * Added new DTSI for AXP209
	  * Added support for cubietruck and olinuxino-micro

Changes since v2:

	- Added a new patch for multi_v7_defconfig to enable MFD core
	  and subsystems

	- DT:
	  * Dropped axp,system-power-controller property from DTS
	  * Moved compatible and interrupt-related properties from the
	    DTSI file to the DTS board files

	- Regulators subsystem:
	  * Deleted useless struct axp20x_regulators
	  * Added a warning when out of specs values are used for the
	    dcdc frequency

	- MFD core:
	  * Fixed coding style
	  * Removed IDs from device table for i2c

	- Bindings documentation:
	  * Several corrections and fixes

Changes since v3:

	- Removed x-powers-axp209.dtsi file
	- Rewritten bindings document

	- MFD core:
	  * Fixed casting
	  * Better comments / documentation

	- Input misc PEK driver:
	  * Timings are now expressed in ms and the sysfs appies the
	    closest possible value
	  * No more useless pretty-printing
	  * Removed devm_request_threaded_irq in favour of
	    devm_request_any_context_irq
	  * Moved from input attributes to platform device attributes

	- Regulators subsystem:
	  * Removed suspend mode (axp20x_set_suspend_voltage)
	  * Added regulators input supply

	- DT:
	  * DTs doesn't include anymore the dtsi
	  * Added input supplies for regulators

Changes since v4:

	- Removed regulator patches already applied / acked by Mark Brown

	- Input misc PEK driver:
	  * Don't print anymore the "us" unit
	  * Added cleanup for attributes when unbindind the device
	  * Fixed error code returned when device_create_file() fails

	- DT:
	  * Enable all the regulators on at boot-time
       	  * Removed min and max microvolts for all the regulators but DCDC2
	  * Moved the axp_ipsout regulator outside the MFD node
	  
	- MFD core:
	  * The supply regulators are now specified in the MFD driver using
	    regulator_bulk_register_supply_alias() and the .parent_supplies
	    in the MFD cell

[PATCH v5 1/8] mfd: AXP20x: Add mfd driver for AXP20x PMIC

[Carlo Caione]

This patch introduces the preliminary support for PMICs X-Powers AXP202
and AXP209. The AXP209 and AXP202 are the PMUs (Power Management Unit)
used by A10, A13 and A20 SoCs and developed by X-Powers, a sister company
of Allwinner.

The core enables support for two subsystems:
- PEK (Power Enable Key)
- Regulators

There is still a small bug in the MFD core that causes hitting the

WARN_ON(!list_empty(&dev->devres_head));

in linux/drivers/base/dd.c#L272 when using the
regulator_bulk_register_supply_alias(). The warning complains that the MFD
core is trying to probe a device that has devres attached.
Charles Keepax is looking for this problem and a patch should be submitted
soon, see http://www.spinics.net/lists/linux-input/msg31099.html and

[PATCH v5 1/8] mfd: AXP20x: Add mfd driver for AXP20x PMIC

[Carlo Caione]

This patch introduces the preliminary support for PMICs X-Powers AXP202
and AXP209. The AXP209 and AXP202 are the PMUs (Power Management Unit)
used by A10, A13 and A20 SoCs and developed by X-Powers, a sister company
of Allwinner.

The core enables support for two subsystems:
- PEK (Power Enable Key)
- Regulators

Signed-off-by: Carlo Caione <carlo@caione.org>
Acked-by: Lee Jones <lee.jones@linaro.org>
---

There is still a small bug in the MFD core that causes hitting the

WARN_ON(!list_empty(&dev->devres_head));

in linux/drivers/base/dd.c#L272 when using the
regulator_bulk_register_supply_alias(). The warning complains that the MFD
core is trying to probe a device that has devres attached.
Charles Keepax is looking for this problem and a patch should be submitted
soon, see http://www.spinics.net/lists/linux-input/msg31099.html and
following

[PATCH v5 4/8] input: misc: Add driver for AXP20x Power Enable Key

[Carlo Caione]

This patch add support for the Power Enable Key found on MFD AXP202 and
AXP209. Besides the basic support for the button, the driver adds two
entries in sysfs to configure the time delay for power on/off.

Well, we have the schematics for most of these boards (at least all
the cubie and olinuxinos).

As far as the other boards are concerned, if we don't have that
information, I'd say leave them alone until someone has access to
these informations.

Well, we have the schematics for most of these boards (at least all
the cubie and olinuxinos).

As far as the other boards are concerned, if we don't have that
information, I'd say leave them alone until someone has access to
these informations.

What do you mean exactly with "leave them alone". The problem is that
if the regulator is not explicitly marked as always-on, it is disabled
at boot time, so I think that the most safe thing to do is leave them
on to avoid turning off something at boot time that could be
important.

What do you mean exactly with "leave them alone". The problem is that
if the regulator is not explicitly marked as always-on, it is disabled
at boot time, so I think that the most safe thing to do is leave them
on to avoid turning off something at boot time that could be
important.

What I mean is that no information is still better than wrong
informations. If you don't have the schematics, then don't do anything
on this boards. Hopefully, someone with more infos on this will know
what to do.

Moreover, I have the feeling that you just copy pasted all the
informations on this patch. The first example I'm seeing is the
cubieboard, for which we do have the schematics, and this patch says
that ldo4 is used for HDMI, and that is required to stays always on,
while LDO4 doesn't seem to be used at all, and that HDMI takes
directly its input source from DC-5V.

I guess you need some more refining on this patch.

What I mean is that no information is still better than wrong
informations. If you don't have the schematics, then don't do anything
on this boards. Hopefully, someone with more infos on this will know
what to do.

Moreover, I have the feeling that you just copy pasted all the
informations on this patch. The first example I'm seeing is the
cubieboard, for which we do have the schematics, and this patch says
that ldo4 is used for HDMI, and that is required to stays always on,
while LDO4 doesn't seem to be used at all, and that HDMI takes
directly its input source from DC-5V.

I guess you need some more refining on this patch.

I partially agree here. Not specifying the voltage range for the
regulators but only keeping them always-on from a practical point of
view means that we do nothing with those regulators (see also
https://www.mail-archive.com/linux-input-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg09532.html

The names for the regulators are taken from the original Allwinner
driver and (of course) they can have nothing to do with the function
they have in the board. I agree that this could be misleading so I'll
change them with more general names. Concerning LDO4 that is always
on, it was off until this v4, but I changed it back to have one common
DT representation among all the boards.

> I guess you need some more refining on this patch.

Ok, I'll submit a v6 only for this patch.

I'm sorry, you did a great job on this PMIC driver, but this is just
wrong. I'm completely fine with the names. What I'm not fine with is
all this "one common DT representation across all boards". Pretty much
all the boards are wired differently when it comes to regulators. Why
do you want to just do some copy pasting without any checking on the
schematics side if not just for the joy of duplicating code?

Please, please, *please* make sure that the informations you put in

Yes.

Weren't you in receipt of my email sent out an hour before this one?

I thought you were re-sending the test though (v6?).

If you can set that, complete with all the Acks, I'd be much obliged.
