NanoPi R4S has a EEPROM attached to the 2nd I2C bus (U92), which stores the MAC address. Changes in v3: - Added address-cells and size-cells Changes in v2: - Added the size of EEPROM - Added `mac-address` cell to pass the MAC address to kernel - Removed `read-only` property in EEPROM node Signed-off-by: Tianling Shen <cnsztl@gmail.com> --- .../boot/dts/rockchip/rk3399-nanopi-r4s.dts | 20 +++++++++++++++++++ 1 file changed, 20 insertions(+)
