[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The new compatible strings are defined as standalone enums without a generic fallback, causing drivers to fail to probe.
- [Low] The commit message description starts with a lowercase letter, violating MFD subsystem guidelines.

--- Patch [4]: [PATCH v7 4/6] dt-bindings: mfd: motorola-cpcap: document Mapphone and Mot CPCAP ---
commit d9f93935d00aa3510052461fef588d4ce3014eed
Author: Svyatoslav Ryhel <clamor95@gmail.com>

dt-bindings: mfd: motorola-cpcap: document Mapphone and Mot CPCAP

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

[Severity: Low]
This isn't a bug, but should the description part of the commit message be
capitalized? The MFD subsystem guidelines typically expect a capitalized
description after the subsystem prefix.

[Severity: Medium]
Since these new compatible strings are defined as standalone enums without a
generic fallback, will the core driver fail to probe these devices? 

Looking at drivers/mfd/motorola-cpcap.c, cpcap_of_match[] lacks a match for
these specific strings:

static const struct of_device_id cpcap_of_match[] = {
	{ .compatible = "motorola,cpcap", },
	{ .compatible = "st,6556002", },
	{},
};

Are there plans to update the driver's match table to recognize these new
standalone compatibles, or could a generic fallback like "motorola,cpcap" be
added to the bindings?
