ARM: dts: stm32: Add PTP clock to Ethernet controller
Add the PTP clock to the Ethernet controller. Otherwise, the driver uses the main clock to derive the PTP frequency which is not necessarily the correct one. Tested with linuxptp on Olimex STMP1-OLinuXino-LIME2. Signed-off-by: Kurt Kanzenbach <[email protected]> Signed-off-by: Alexandre Torgue <[email protected]>
