kernel: rtl8366_smi: explicitly set phy addr for switch
By default rtl8366_smi use phy addr 0 at mii-bus to access switch registers. This patch allow to set it explicitly in dts-file: rtl8367 { compatible = "realtek,rtl8367b"; phy-id = <29>; /* switch address at mii-bus */ realtek,extif2 = <1 0 1 1 1 1 1 1 2>; mii-bus = <&mdio>; cpu-port = <7>; } Use default 0 address if not set. Backward compatibility tested on tplink archer c2 v1 (rtl8367rb switch) Signed-off-by: Serge Vasilugin <vasilugin@yandex.ru> [code style fixes, add explicit phy_id assignment in probe_plat, use phy-id instead of phy_id for of property name] Signed-off-by: Chuanhong Guo <gch981213@gmail.com> [rebase] Signed-off-by: Gaspare Bruno <gaspare@anlix.io> [added phy_id to struct rtl8366_smi] Signed-off-by: Mieczyslaw Nalewaj <namiltd@yahoo.com>
