Subject: [PATCH 0/2] regulator: fp9931: fix voltage mapping and runtime PM issues
Date: Tue, 21 Jul 2026 17:59:57 +0800	[thread overview]
Message-ID: <20260721095959.1855436-1-robby.cai@oss.nxp.com> (raw)

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

Hi,

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

Patch 1 fixes an off-by-one error in the VPOS/VNEG voltage selector
table and aligns it with the datasheet-defined voltage mapping [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,
Robby
