What comes to the ROHM drivers, I am ok with the "swnode stuff" proposed
by Dmitry (if it helps with cropping some legacy). Still, from the ROHM
driver POV, I sure have no problems with just simple zeroing the gpios
and providing the IRQ which in driver side is clean(ish) and simpl(ish) :)
So, in case someone opposes Dmitry's changes, for ROHM drivers:

You are slowly wearing me down on the 80 limit by pointing out lots of

Show us what that looks like with this series squashed into a single patch
as a percursor. It might be worth doing as part of that larger work - on its
own it's not justified.
A series must be applicable 1 patch at a time without breaking anything.

Normally I'd fix it manually while applying, but kernel test robot found
newly added compiler warnings in the meantime, so please include that in
the followup v3.

* [PATCH v4 5/6 RESEND] mfd: motorola-cpcap: diverge configuration per-board

In-Reply-To: <20260428153611.142816-1-clamor95@gmail.com>
MFD have rigid subdevice structure which does not allow flexible dynamic
subdevice linking. Address this by diverging CPCAP subdevice composition
to take into account board specific configuration.
Create a common default subdevice composition, rename existing subdevice
composition into cpcap_mapphone_mfd_devices since it targets mainly
Mapphone board.
Removed st,6556002 as it is no longer applicable to all cases and
duplicates motorola,cpcap, which is used as the default composition.

-
-Optional subnodes:
-
-The sub-functions of CPCAP get their own node with their own compatible values,
-which are described in the following files:
-
-- Documentation/devicetree/bindings/power/supply/cpcap-battery.yaml
-- Documentation/devicetree/bindings/power/supply/cpcap-charger.yaml

-- Documentation/devicetree/bindings/iio/adc/motorola,cpcap-adc.yaml
-
-The only exception is the audio codec. Instead of a compatible value its
-node must be named "audio-codec".
-
-Required properties for the audio-codec subnode:
-
-- #sound-dai-cells = <1>;
-- interrupts : should contain jack detection interrupts, with headset
- detect interrupt matching "hs" and microphone bias 2
- detect interrupt matching "mb2" in interrupt-names.
-- interrupt-names : Contains "hs", "mb2"
-
-The audio-codec provides two DAIs. The first one is connected to the
-Stereo HiFi DAC and the second one is connected to the Voice DAC.
-

* [PATCH v4 0/6 RESEND] mfd: cpcap: convert documentation to schema and add Mot board support
From: Svyatoslav Ryhel @ 2026-04-28 15:36 UTC (permalink / raw)
To: Dmitry Torokhov, Rob Herring, Krzysztof Kozlowski, Conor Dooley,
Lee Jones, Pavel Machek, Svyatoslav Ryhel, David Lechner,

Cc: linux-input, devicetree, linux-kernel, linux-leds
The initial goal was only to add support for the CPCAP used in the Mot
Tegra20 board; however, since the documentation was already partially
converted, I decided to complete the conversion to schema too.
The CPCAP regulator, leds, rtc, pwrbutton and core files were converted
from TXT to YAML while preserving the original structure. Mot board
compatibility was added to the regulator and core schema. Since these
were one-line patches, they were not separated into dedicated commits;
however, the commit message notes this for both cases.
Finally, the CPCAP MFD was slightly refactored to improve support for
multiple subcell compositions.
---
Changes in v2:
- fixed code style
- rtc conversion was picked, so patch dropped
- added audio ports description into mfd schema
- splitted schema conversion and compatible addition
- minor style improvements and typo fixes
Changes in v3:
- added regulator node names list into pattern
- filled spi_device_id with driver data
- ADC patches were picked, so changes dropped
Changes in v4:
- dropped regulator patches (applied)
