Subject: net: stmmac: dwmac-sun8i: Allow all RGMII modes
From: Chen-Yu Tsai <wens@xxxxxxxx>
[ Upstream commit f1239d8aa84dad8fe4b6cc1356f40fc8e842db47 ]
Allow all the RGMII modes to be used. This would allow us to represent
the hardware better in the device tree with RGMII_ID where in most
cases the PHY's internal delay for both RX and TX are used.
