Greetings,

Thank you all for your feedback. I have integrated your recommendations
into this revised patch series (v2); please disregard the previous thread.

Summary of Changes:
- Patch 1/3: Updates the Device Tree Schema bindings to include
  "qcom,pmi8998-vbus-reg" for PMI8998 support.
- Patch 2/3: Extends the Qualcomm USB VBUS regulator driver to support
  PMI8998, dynamically configuring the regulator based on the PMIC type.
- Patch 3/3: Adds the VBUS regulator node to pmi8998.dtsi, enabling
  USB Type-C VBUS support.

Motivation:
To enable VBUS operation on the SDM845 platform PMI8998 PMIC.

Kernel Version & Testing:
- These patches were developed and tested on Linux 6.13.
- Attempting to run Linux 6.14-rc2 on our Lantronix SOM resulted in a
  hard crash, making it unsuitable for validation.
- Validation was performed using a modified device tree, confirming proper
  regulator configuration.
- No regressions were observed on existing PMIC configurations.

Next Steps:
If there are any suggestions or required changes, please let me know.
I will be happy to revise and address any concerns.

Thanks again,
James A. MacInnes
