Subject: [RFC 5/5] arm64: dts: imx8mq: Add the opp table and the cpu-supply nodes
Date: Wed, 13 Feb 2019 19:05:17 +0000	[thread overview]
Message-ID: <1550084693-9797-6-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1550084693-9797-1-git-send-email-abel.vesa@nxp.com>

Add the opp table containing only non over drive opps.
Also add the cpu-supply nodes for the A53 cores in the EVK board.
