[PATCH v4 0/6] mfd: cpcap: convert documentation to schema and add Mot board support

[PATCH v4 0/6] mfd: cpcap: convert documentation to schema and add Mot board support

[Svyatoslav Ryhel]

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)

[PATCH v4 4/6] dt-bindings: mfd: motorola-cpcap: document Mapphone and Mot CPCAP

[Svyatoslav Ryhel]

Add compatibles for Mapphone and Mot CPCAP subdevice compositions. Both
variations cannot use st,6556002 fallback since they may be based on
different controllers.

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

[Svyatoslav Ryhel]

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Removed st,6556002 as it is no longer applicable to all cases and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.

My bot found errors running 'make dt_binding_check' on your patch:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.kernel.org/project/devicetree/patch/20260417071106.21984-2-clamor95@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
