Subject: [PATCH v3 1/7] power: act8945a_charger: Remove "battery_temperature"
Date: Fri, 29 Jul 2016 09:25:22 +0800	[thread overview]
Message-ID: <1469755528-8413-2-git-send-email-wenyou.yang@atmel.com> (raw)
In-Reply-To: <1469755528-8413-1-git-send-email-wenyou.yang@atmel.com>

Remove "battery_temperature" member, it is redundant, it is the
hardware's responsibility to handle TH pin properly.
It is unnecessary to use the dt property to check if there is
a battery temperature monitor or not.
