Add device-tree binding documentation SFP transceivers. Support for SFP transceivers has been recently introduced (drivers/net/phy/sfp.c). Signed-off-by: Baruch Siach <baruch@tkos.co.il> --- The SFP driver is on net-next. Not sure about the rate-select-gpio property name. The SFP+ standard (not supported yet) uses two signals, RS0 and RS1. RS0 is compatible with the SFP rate select signal, while RS1 controls the Tx rate. --- Documentation/devicetree/bindings/net/sff-sfp.txt | 24 +++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/sff-sfp.txt
