[PATCH v3 0/2] hwmon/pmbus: isl68137: Add RAA228942/RAA228943 support

[Dawei Liu]

Add support for Renesas RAA228942 and RAA228943 digital
dual-output 16-phase PWM controllers.

Changes in v3:
  - Update commit message to clarify hardware differences
    (suggested by Krzysztof Kozlowski)
  - Drop enum cleanup patch as it has been merged

Changes in v2:
  - Remove entire unused enum chips
    (suggested by Guenter Roeck)
  - Improve commit message to clarify hardware difference
  - Split enum chips cleanup into separate patch

[PATCH 1/2] hwmon: (pmbus/isl68137) Add support for Renesas RAA228942 and RAA228943

[Dawei Liu]

RAA228942 and RAA228943 are Renesas digital dual-output
16-phase (X+Y <= 16) PWM controllers with 2-rail non-TC
driver configuration. They have different hardware
interfaces and feature sets compared to existing
family members.

Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):
https://elixir.bootlin.com/linux/v6.4-rc1/source/Documentation/process/submitting-patches.rst#L597

Anyway, same feedback as last time. I responded to your answer but you
did not give me chance anymore and sent v3.

Best regards,
Krzysztof
