-Subject: [PATCH] net: stmmac: sunxi platfrom extensions for GMAC in Allwinner
- A20 SoC's
-
-The Allwinner A20 has an ethernet controller that seems to be
-an early version of Synopsys DesignWare MAC 10/100/1000 Universal,
-which is supported by the stmmac driver.
-
-Allwinner's GMAC requires setting additional registers in the SoC's
-clock control unit.
-
-The exact version of the DWMAC IP that Allwinner uses is unknown,
-thus the exact feature set is unknown.
-
-Signed-off-by: Chen-Yu Tsai <wens@csie.org>
