    ARM: dts: NSP: Enable SFP on bcm958625hr · 046ead61
    Florian Fainelli authored
    Enable the SFP connected to port 5 of the switch and wire up all GPIOs
    to the SFP cage. Because of a hardware limitation of the i2c controller
    on the iProc SoCs which prevents large i2c (> 63 bytes) transactions to
    work, we use the i2c-gpio interface instead, which does not have that
    limitation. This allows us to read the SFP module EEPROM, which would
    not be possible otherwise since it exceeds that size during a single
    read transfer.
