4 Subject: [PATCH] ARM: dts: sun7i: Add GMAC clock node to sun7i DTSI
6 The GMAC uses 1 of 2 sources for its transmit clock, depending on the
7 PHY interface mode. Add both sources as dummy clocks, and as parents
8 to the GMAC clock node.

24 + * The actual TX clock rate is not controlled by the gmac_tx clock.
