The PTP clock for the Tegra234 MGBE device is incorrectly named 'ptp-ref' and should be 'ptp_ref'. This is causing the following warning to be observed on Tegra234 platforms that use this device: ERR KERN tegra-mgbe 6800000.ethernet eth0: Invalid PTP clock rate WARNING KERN tegra-mgbe 6800000.ethernet eth0: PTP init failed Although this constitutes an ABI breakage in the binding for this device, PTP support has clearly never worked and so fix this now so we can correct the device-tree for this device. Note that the MGBE driver still supports the legacy 'ptp-ref' clock name and so older/existing device-trees will still work, but given that this is not the correct name, there is no point to advertise this in the binding.
