Subject: [PATCH] mfd: axp20x: Mark axp288 CHRG_BAK_CTRL register volatile
Date: Fri, 22 Dec 2017 13:35:09 +0100 [thread overview]
Message-ID: <20171222123509.9503-1-hdegoede@redhat.com> (raw)
The input current limit bits get updated by the charger detection logic,
so we should not cache the contents of this register.
