Subject: [PATCH] regulator: axp20x: fix LDO2/4 description
Date: Wed, 23 Sep 2020 08:51:42 +0800 [thread overview]
Message-ID: <20200923005142.147135-1-icenowy@aosc.io> (raw)
Currently we wrongly set the mask of value of LDO2/4 both to the mask of
LDO2, and the LDO4 voltage configuration is left untouched. This leads
to conflict when LDO2/4 are both in use.
Fix this issue by setting different vsel_mask to both regulators.
Fixes: db4a555f7c4c ("regulator: axp20x: use defines for masks")
