net: dsa: microchip: Support optional 125MHz SYNCLKO output
The KSZ9477 series chips have a SYNCLKO pin which by default outputs a 25MHz clock, but some board setups require a 125MHz clock instead. Added a microchip,synclko-125 device tree property to allow indicating a 125MHz clock output is required. Signed-off-by: Robert Hancock <hancock@sedsystems.ca> Signed-off-by: David S. Miller <davem@davemloft.net>
