Subject: [PATCH] arm64: dts: imx8mn: Init rates and parents configs for clocks
Date: Fri, 10 Jan 2020 07:20:31 +0000 [thread overview]
Message-ID: <1578640589-17210-1-git-send-email-peng.fan@nxp.com> (raw)
From: Peng Fan <peng.fan@nxp.com>
Add the initial configuration for clocks that need default parent and rate
setting.
NoC sources from SYS PLL3, running at 600MHz. Audio AHB/IPG clks needs
to run at 400MHz for better performance.
