The dsa core now supports reading from and writing to a switch EEPROM if connected. Describe optional devicetree property indicating that an EEPROM is present and its size. Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- v3: - eeprom-length property is attached to switch devicetree node, not to dsa node. v2: - Added patch Documentation/devicetree/bindings/net/dsa/dsa.txt | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-)
