Subject: [PATCH 5/7] ARM: dts: sun8i: a83t: cubietruck-plus: Add AXP818 regulator nodes
Date: Fri, 29 Sep 2017 11:25:12 +0800 [thread overview]
Message-ID: <20170929032514.31727-6-wens@csie.org> (raw)
In-Reply-To: <20170929032514.31727-1-wens@csie.org>
This patch adds device nodes for all the regulators of the AXP818 PMIC.
References to the 3.3V dummy regulator are replaced, and it is disabled.
