ARM: dts: sun6i: hummingbird: Add ethernet phy reset gpio properties
On the Hummingbird A31 board, the RTL8211E ethernet phy has its reset line connect to a gpio pin, instead of floating like on other boards. Add the stmmac properties for describing the reset gpio. The reset delays were taken from the RTL8211E datasheet. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
