[PATCH v6 00/10 RESEND] Add RT5033 charger device driver

[PATCH v6 00/10 RESEND] Add RT5033 charger device driver

[Jakob Hauser]

This patchset adds the charger driver "rt5033-charger". It is part of the
multifunction device rt5033. The patchset is based on an older version by
Beomho Seo of March 2015. For more information on the history and setup of
the patchset see the cover sheet of version v1, there is a link further down
below the changelog.

RESEND: Sorry for spamming. The first try of sending v6 got interrupted and
was split into two threads on the lore list. Therefore sending it again.

Changes in v6:
 - Patch 5: In function rt5033_charger_probe() after
   calling rt5033_charger_dt_init() replaced the return value from "-ENODEV"
   to "PTR_ERR(charger->chg)", as suggested by Christophe.
 - Patch 9: Changed the patch from adding "power-supplies: true" to replacing
   "additionalProperties: false" by "unevaluatedProperties: false", as
   suggested by Krzysztof.

[PATCH v6 01/10 RESEND] mfd: rt5033: Drop rt5033-battery sub-device

[Jakob Hauser]

From: Stephan Gerhold <stephan@gerhold.net>

The fuel gauge in the RT5033 PMIC (rt5033-battery) has its own I2C bus
and interrupt lines. Therefore, it is not part of the MFD device
and needs to be specified separately in the device tree.

[PATCH v6 02/10 RESEND] mfd: rt5033: Fix chip revision readout

[Jakob Hauser]

After reading the data from the DEVICE_ID register, mask 0x0f needs to be
applied to extract the revision of the chip [1].

The other part of the DEVICE_ID register, mask 0xf0, is a vendor identification
code. That's how it is set up at similar products of Richtek, e.g. RT9455 [2]
page 21 top.

[PATCH v6 03/10 RESEND] mfd: rt5033: Fix STAT_MASK, HZ_MASK and AICR defines

[Jakob Hauser]

The charger state mask RT5033_CHG_STAT_MASK should be 0x30 [1][2].

The high impedance mask RT5033_RT_HZ_MASK is actually value 0x02 [3] and is
assosiated to the RT5033 CHGCTRL1 register [4]. Accordingly also change
RT5033_CHARGER_HZ_ENABLE to 0x02 to avoid the need of a bit shift upon
application.

For input current limiting AICR mode, the define for the 1000 mA step was
missing [5]. Additionally add the define for DISABLE option. Concerning the
mask, remove RT5033_AICR_MODE_MASK because there is already
RT5033_CHGCTRL1_IAICR_MASK further up. They are redundant and the upper one
makes more sense to have the masks of a register colleted there as an
overview.

[PATCH v6 04/10 RESEND] mfd: rt5033: Apply preparatory changes before adding rt5033-charger driver

[Jakob Hauser]

Order the register blocks to have the masks in descending manner.

Add new defines for constant voltage shift (RT5033_CHGCTRL2_CV_SHIFT),
MIVR mask (RT5033_CHGCTRL4_MIVR_MASK), pre-charge current shift
(RT5033_CHGCTRL4_IPREC_SHIFT), internal timer disable
(RT5033_INT_TIMER_DISABLE), termination disable (RT5033_TE_DISABLE),
CFO disable (RT5033_CFO_DISABLE), UUG disable (RT5033_CHARGER_UUG_DISABLE).

The fast charge timer type needs to be written on mask 0x38
(RT5033_CHGCTRL3_TIMER_MASK). To avoid a bit shift on application, change the
values of the timer types to fit the mask. Added the timout duration as a
comment. And the timer between TIMER8 and TIMER12 is most likely TIMER10, see
e.g. RT5036 [1] page 28 bottom.

Add value options for MIVR (Minimum Input Voltage Regulation).

Move RT5033_TE_ENABLE_MASK to the block "RT5033 CHGCTRL1 register", in order
to have the masks of the register collected there. To fit the naming scheme,
rename it to RT5033_CHGCTRL1_TE_EN_MASK.

Move RT5033_CHG_MAX_CURRENT to the block "RT5033 charger fast-charge current".

Add new defines RT5033_CV_MAX_VOLTAGE and RT5033_CHG_MAX_PRE_CURRENT to the
blocks "RT5033 charger constant charge voltage" and "RT5033 charger pre-charge
current limits".

In include/linux/mfd/rt5033.h, turn power_supply "psy" into a pointer in order
to use it in devm_power_supply_register().

[PATCH v6 05/10 RESEND] power: supply: rt5033_charger: Add RT5033 charger device driver

[Jakob Hauser]

This patch adds device driver of Richtek RT5033 PMIC. The driver supports
switching charger. rt5033 charger provides three charging modes. The charging
modes are pre-charge mode, fast charge mode and constant voltage mode. They
vary in charge rate, the charge parameters can be controlled by i2c interface.

[PATCH v6 06/10 RESEND] power: supply: rt5033_charger: Add cable detection and USB OTG supply

[Jakob Hauser]

Implement cable detection by extcon and handle the driver according to the
connector type.

There are basically three types of action: "set_charging", "set_otg" and
"set_disconnect".

A forth helper function to "unset_otg" was added because this is used in both
"set_charging" and "set_disconnect". In the first case it covers the rather
rare event that someone changes from OTG to charging without disconnect. In
the second case, when disconnecting, the values are set back to the ones from
initialization to return into a defined state.

Additionally, there is "set_mivr". When connecting to e.g. a laptop/PC, the
minimum input voltage regulation (MIVR) shall prevent a voltage drop if the
cable or the supply is weak. The MIVR value is set to 4600MV, same as in the
Android driver [1]. When disconnecting, MIVR is set back to DISABLED.

In the function rt5033_get_charger_state(): When in OTG mode, the chip
reports status "charging". Change this to "discharging" because there is
no charging going on in OTG mode [2].

[PATCH v6 07/10 RESEND] power: supply: rt5033_battery: Move struct rt5033_battery to battery driver

[Jakob Hauser]

Move struct rt5033_battery from the mfd header into the battery driver because
it's not used by others.

Within struct rt5033_battery, remove the line "struct rt5033_dev *rt5033;"
because it doesn't get used.

In rt5033.h, remove #include <linux/power_supply.h>, it's not necessary
anymore.

In rt5033_battery.c, remove #include <linux/mfd/rt5033.h>, it's not necessary
anymore either. Instead add #include <linux/regmap.h> and

[PATCH v6 08/10 RESEND] power: supply: rt5033_battery: Adopt status property from charger

[Jakob Hauser]

The rt5033-battery fuelgauge can't get a status by itself. The rt5033-charger
can, let's get this value.

To get the charger as a "supplier" from the devicetree, the "of_node" needs
to be initiated.

Additionally, in the probe function replace dev_err() with dev_err_probe(),
this will avoid printing an error for -EPROBE_DEFER when the battery driver
probes before the charger driver.

Currently this is not in use. The rt5033 charger driver gets introduced 
by this pachset.

The struct rt5033_charger was added in Dec 2014 with the mfd driver [1] 
but the charger driver didn't make it [2] and further effort to 
implement it phased out [3].

You're waiting on me.  I will apply all of the patches and submit a PR.

You're in the queue - please stand-by.

I just realized that there is one patch missing in the immutable branch 
"ib-mfd-power-v6.5" [1]. Unfortunately I haven't noticed earlier. The 
immutable branch holds 9 patches, the patchset has 10 patches [2]. The 
missing patch is No. 6 "power: supply: rt5033_charger: Add cable 
detection and USB OTG supply".

As this patch No. 6 affects only the file 
drivers/power/supply/rt5033_charger.c and is the last patch on that 
file, it's no problem to add this patch on top of the other patches.

Could you submit another pull request for the v6.5 merge window to add 
this patch?

Did you take this pull-request?

If so, would you like to apply the missing patch or would you like me to
take it via MFD (without a subsequent PR)?

Re: [GIT PULL] Immutable branch between MFD and Power due for the v6.5 merge window

[Jakob Hauser]

Hi Sebastian,

The patch 6 "power: supply: rt5033_charger: Add cable detection and USB 
OTG supply" of the series v6 RESEND of rt5033-charger is still missing.

The lore link of the series v6 RESEND is above [2]. The patchwork link 
to v6 RESEND is:
https://patchwork.kernel.org/project/linux-pm/list/?series=747771&state=%2A&archive=both

Additionally, there were two follow-up clean-up patches. There were no 
review comments so far. Lore and patchwork links are:
https://lore.kernel.org/linux-pm/cover.1686948074.git.jahau@rocketmail.com/T/#t
https://patchwork.kernel.org/project/linux-pm/list/?series=758018&state=%2A&archive=both

Could you apply those three patches? (1x patch 6 of v6 RESEND series + 
2x clean-up patches.)

I've just noticed that a new patch by Rob was added to rt5033-charger. 
Can you rebase the other three patches by your own or do you want me to 
rebase and resend them?

Multiple fixes now follow this patch, so I am unapplying it.

Sebastian, would you mind collecting it up please?

I'm leaving for a two week hiking trip (with basically no internet
access) in some hours. My planed return date is basically when Linus
is expected to tag 6.6-rc1, so I will not queue any more patches and
send my pull request early (within the next few hours).

I planned to catch up with the power-supply backlog last week during
Chaos Communication Camp, but it was too hot to do any sensible
review. Now I expect to process the power-supply backlog in the
week after the merge window.

Greetings and sorry for the inconvenience,

-- Sebastian

The patch 6 of the rt5033-charger series v6 gathered some issues. For 
all of them a solution was provided. Thanks to everyone involved! 
However, I don't know what's the best way to put them together.

- As the patch 6 was forgotten to apply with the others of the
   patchset, in the meantime another small patch by Rob sneaked in. The
   patch 6 needs to be rebased on Rob's patch. It affects the includes.
   Would be nice to order them alphabetically after rebase.

- After patch 6 was added on top of Rob's patch in linux-next, there
   was a build failure. This is because "linux/of.h" now explicitly
   needs to be added to the rt5033-charger driver. Stephen Rothwell
   provided a fix. I'm not sure on the order: Maybe that needs to be
   added before adding patch 6 to avoid the build failure when the
   kernel test bot checks each commit separately.
 
https://lore.kernel.org/linux-next/20230821125741.3a2474d7@canb.auug.org.au/T/#u

- Beyond that, the kernel test bot also complained about undefined
   reference related to extcon. I didn't understand why this happens
   because the driver has "linux/extcon.h" included. Randy was attentive
   and provided a fix. Here again I'm not sure about the order, I guess
   this should be added before adding patch 6 to avoid build failures if
   each commit is tested separately.
   Kernel test bot complaints:
     x86_64 clang 
https://lore.kernel.org/oe-kbuild-all/202308220324.LsI8q3ML-lkp@intel.com/T/#u
     x86_64 gcc 
https://lore.kernel.org/oe-kbuild-all/202308240723.O2rW0InU-lkp@intel.com/T/#u
     arm gcc 
https://lore.kernel.org/oe-kbuild-all/202308250617.ue4uQxWa-lkp@intel.com/T/#u
   Fix by Randy:
 
https://lore.kernel.org/linux-pm/20230828224201.26823-1-rdunlap@infradead.org/T/#u

- Yang noticed that the mutex_unlock() is not handled correctly in
   some error path and provided a fix:
 
https://lore.kernel.org/linux-pm/20230822030207.644738-1-yangyingliang@huawei.com/T/#u

- There are two clean-up patches by me. They need to be rebased to the
   patches mentioned above but there shouldn't be conflicts with them.
 
https://lore.kernel.org/linux-pm/cover.1686948074.git.jahau@rocketmail.com/T/#u

Please also note that the commit hash in the linked fixes above refers 
to linux-next, where the patch 6 had been applied. As the patch was 
dropped later on, I don't know what this means for the commit hashes in 
the fixes.

What's the best way to proceed? Can you put these patches together? Or 
do you want me something to do?

Kind regards,
Jakob

You need to do this yourself.

Rebase all of the fixes on top of v6.6-rc1 (which will be released in a
little under a week).  Ensure that each patch builds as it's applied so
as not to harm bisecability.  If you have to squash them to prevent
built-breakages, then so be it, but don't forget to credit the
contributors.  Once complete, post as a set and we'll take it from
there.

Fully agreed. I expect to see a new series with the missing bits.
