Subject: [PATCH v2 0/4] J721E: Use external clock in EVM for SERDES
Date: Thu, 3 Jun 2021 20:04:23 +0530 [thread overview]
Message-ID: <20210603143427.28735-1-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.
Changes from v1:
1) Fixed clock names as suggested by Nishanth
2) Limit to < 100 lines
v1: http://lore.kernell.org/r/20210512151209.27560-1-kishon@ti.com
