arm64: dts: ti: k3-am642-main: fix ports mac properties
[ Upstream commit 50c9bfc ] The current device tree CPSW3g node adds non-zero "mac-address" property to the ports, which prevents random MAC address assignment to network devices if bootloader failed to update DT. This may cause more then one host to have the same MAC in the network. mac-address = [00 00 de ad be ef]; mac-address = [00 01 de ad be ef]; In addition, there is one MAC address available in eFuse registers which can be used for default port 1. Hence, fix ports MAC properties by: - resetting "mac-address" property to 0 - adding ti,syscon-efuse = <&main_conf 0x200> to Port 1 Fixes: 3753b12 ("arm64: dts: ti: k3-am64-main: Add CPSW DT node") Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Reviewed-by: Vignesh Raghavendra <vigneshr@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Link: https://lore.kernel.org/r/20210608184940.25934-1-grygorii.strashko@ti.com Signed-off-by: Sasha Levin <sashal@kernel.org>
