Subject: [PATCH 5/6] arm64: dts: zynqmp: Move USB clocks to dwc3 node
Date: Fri, 14 Jan 2022 18:39:03 -0500 [thread overview]
Message-ID: <20220114233904.907918-6-sean.anderson@seco.com> (raw)
In-Reply-To: <20220114233904.907918-1-sean.anderson@seco.com>
These clocks are not used by the dwc3-xilinx driver except to
enable/disable them. Move them to the dwc3 node so its driver can use
them to configure the reference clock period.
