[PATCH v2 13/14] arm64: dts: ti: k3-j721e-common-proc-board: Use external clock for SERDES

From: Kishon Vijay Abraham I
Date: Tue Dec 22 2020 - 02:07:25 EST


Use external clock for all the SERDES used by PCIe controller. This will
make the same clock used by the local SERDES as well as the clock
provided to the PCIe connector.
