Chen Minqiang f6d81e2fa1 mt7620: gsw: make IntPHY and ExtPHY share mdio addr 4 possible ... To share mdio addr for IntPHY and ExtPHY, as described in the documentation (MT7620_ProgrammingGuide.pdf). (refer: http://download.villagetelco.org/hardware/MT7620/MT7620_ProgrammingGuide.pdf) when port4 setup to work as gmac mode, dts like: &gsw { mediatek,port4 = "gmac"; }; we should set SYSCFG1.GE2_MODE==0x0 (RGMII). but SYSCFG1.GE2_MODE may have been set to 3(RJ-45) by uboot/default so we need to re-set it to 0x0 before this changes: gsw: 4FE + 2GE may not work correctly and MDIO addr 4 cannot be used by ExtPHY after this changes: gsw: 4FE + 2GE works and MDIO addr 4 can be used by ExtPHY Signed-off-by: Chen Minqiang <ptpt52@gmail.com>		2018-08-06 07:12:31 +02:00
