Subject: [PATCH 2/2] arm64: dts: imx8mq: correct usb controller clocks
Date: Wed, 10 Jul 2019 19:19:17 +0800 [thread overview]
Message-ID: <20190710111917.6615-2-jun.li@nxp.com> (raw)
In-Reply-To: <20190710111917.6615-1-jun.li@nxp.com>
From: Li Jun <jun.li@nxp•com>
The correct clock for "bus_early", "ref", "suspend" should be:
IMX8MQ_CLK_USB1_CTRL_ROOT, IMX8MQ_CLK_USB_CORE_REF, IMX8MQ_CLK_32K,
especially we may need the right suspend clock rate to set register
in controller driver.
