Subject: [PATCH] arm64: dts: ti: k3-am62a7-phyboard-lyra-rdk: Update ethernet internal delay
Date: Fri, 4 Oct 2024 15:10:49 -0700 [thread overview]
Message-ID: <20241004221049.1155022-1-nmorrisson@phytec.com> (raw)
Update the RGMII delay to 2.5ns to improve performance. We use an
additional mapper board for the am62a7 phyBOARD Lyra which makes this
delay necessary.
Signed-off-by: Nathan Morrisson <nmorrisson@phytec.com>
