devicetree binding for stmmac states: - compatible: Should be "snps,dwmac-<ip_version>", "snps,dwmac" For backwards compatibility: "st,spear600-gmac" is also supported. Since dwmac-generic.c calls stmmac_probe_config_dt explicitly, another alternative would have been to remove all compatible strings other than "snps,dwmac" and "st,spear600-gmac" from dwmac-generic.c. However, that would probably do more good than harm, since when trying to figure out what hardware a certain driver supports, you usually look at the compatible strings in the struct of_device_id, and not in some function defined in a completely different file. No functional change intended. Signed-off-by: Niklas Cassel <niklas.cassel@axis.com> Acked-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S. Miller <davem@davemloft.net>
