kernel: rtl8367b: add configuration for extif2
Both rtl8367b and rtl8367s have two extended interface rtl8367rb: 5 port + 2*RGMII/MII rtl8367s: 5 port + SGMII/HSGMI + RGMII/MII (?)rtl8367sb: 5 port + 2*RGMII/MII These interfaces correspond to EXT1 and EXT2 (ports 6 and 7 respectivly). This patch allow to configure EXT2 in dts-file: rtl8367rb { compatible = "realtek,rtl8367b"; cpu_port = <7>; realtek,extif2 = <1 0 1 1 1 1 1 1 2>; mii-bus = <&mdio0>; phy_id = <29>; }; Signed-off-by: Serge Vasilugin <vasilugin@yandex.ru> [fix indent, replace magic value, alter commit message] Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
