Subject: [PATCH 2/3] ARM: dts: arria10: Add stmmac ptp_ref clock

From: Dalon Westergreen <dalon.westergreen@...ux.intel.com>

Add the default stmmac ptp_ref clock for arria10.  The stmmac
driver defaults the ptp_ref clock to the main stmmac clock
if the ptp_ref clock is not set in the devicetree.  This is inappropriate
for the arria10 device.  The default ptp_ref clock is peri_emac_ptp_clk.
