Subject: [PATCH 0/4] J721E: Use external clock in EVM for SERDES
Date: Wed, 12 May 2021 20:42:05 +0530 [thread overview]
Message-ID: <20210512151209.27560-1-kishon@ti.com> (raw)
J721E EVM has clock generator that feeds both to the SERDES and to the
PCIe slot present in the EVM. In order to use common reference clock on
either side of the link, configure SERDES to use external reference
clock.
Previously SERDES used internal reference clock and the attached device
used clock from clock generator in the EVM.

arm64: dts: ti: k3-j721e-main: Fix external refclk input to SERDES
arm64: dts: ti: k3-j721e-main: Add #clock-cells property to serdes DT
node
arm64: dts: ti: k3-j721e-common-proc-board: Use external clock for
SERDES
arm64: dts: ti: k3-j721e-common-proc-board: Re-name "link" name as
"phy"
