Subject: [PATCH 3/3] arm64: dts: Add power controller device node of MT8192
Date: Fri, 4 Sep 2020 14:44:55 +0800	[thread overview]
Message-ID: <1599201895-11013-4-git-send-email-weiyi.lu@mediatek.com> (raw)
In-Reply-To: <1599201895-11013-1-git-send-email-weiyi.lu@mediatek.com>

Add power controller node for MT8192.
In scpsys node, it contains clocks and regmapping of
infracfg for bus protection.
And list all the power domains of MT8192 under scpsys node
to show the dependency between each other through hierarchical
structure.
