Subject: [PATCH 12/16] arm: dts: add mt7623-mt6323.dtsi file
Date: Mon, 23 Jan 2017 12:29:31 +0100 [thread overview]
Message-ID: <1485170975-51813-13-git-send-email-john@phrozen.org> (raw)
In-Reply-To: <1485170975-51813-1-git-send-email-john-Pj+rj9U5foFAfugRpC6u6w@public.gmane.org>
MediaTek produces various PMICs. Which one is used depends on the actual
circuit design. Instead of adding the correct PMIC node to every dts file
we instead add a new intermediate dtsi file which adds the PMIC node.
Additionally we also add the phandles for the regulators to various nodes.
