[PATCH v2 0/2] regulator: fp9931: fix voltage mapping and runtime PM issues

Posted by robby.cai@oss.nxp.com 10 hours ago

From: Robby Cai <robby.cai@nxp.com>

This series fixes two issues in the FP9931/JD9930 regulator driver.

Patch 1 fixes errors in the VPOS/VNEG voltage selector table, correcting
an off-by-one entry and extending the table to cover the full selector
range defined by the datasheet [1].

Patch 2 fixes a Runtime PM reference counting bug in the V3P3 regulator
callbacks that can lead to "Runtime PM usage count underflow!" warnings.

Thanks,

Changes in v2:
- [1/2] Extend VPOSNEG_table[] to cover selectors 0x29-0x3f as defined by the datasheet and reformat the table for readability.
- [2/2] Refine commit message; no code change.
