[PATCH v2 1/2] dt-bindings: hwmon: pmbus: isl68137: Add Renesas RAA229639 and RAA229640

[Colin Huang]

From: Colin Huang <u8813345@gmail.com>

Add Device Tree compatible strings for Renesas RAA229639 and
RAA229640 PMBus devices.

A fallback compatible is not introduced because the available
documentation does not establish DT-level compatibility with
any existing supported device.

[PATCH v2 2/2] hwmon: (pmbus/isl68137): Add Renesas RAA229639 and RAA229640

[Colin Huang]

From: Colin Huang <u8813345@gmail.com>

Add support for the Renesas RAA229639 and RAA229640 PMBus
voltage regulator devices.

Both devices are supported by the existing raa_dmpvr2_2rail
driver variant, so no functional changes are required beyond
adding the corresponding device IDs and OF match entries.

Author: Colin Huang <u8813345@gmail.com>

hwmon: (pmbus/isl68137): Add Renesas RAA229639 and RAA229640

This commit adds support for the Renesas RAA229639 and RAA229640 PMBus
voltage regulator devices. It updates the existing raa_dmpvr2_2rail driver
variant by adding the corresponding device IDs and OF match entries.

[Severity: Low]
Since these new devices are being added to the driver, should they also be
documented in the "Supported chips" list within
Documentation/hwmon/isl68137.rst alongside the existing parts?

Please don't respin before people have a chance to actually respond to
the thread. Please see my commentary on V(this - 1) on the compatiblity
of the devices being added.
