[PATCH V4 3/3] arm64: tegra: Fix Tegra234 MGBE PTP clock

Jon Hunter
2026-04-01T10:30:07Z

The Tegra MGBE PTP clock is incorrectly named as 'ptp-ref' and not
'ptp_ref' and this causing the initialisation of the PTP clock to fail.
The device-tree binding doc for the device and the Tegra MGBE driver
have been updated to use the correct name and so update the device-tree
for Tegra234 as well.
