devicetree binding for stmmac states: - compatible: Should be "snps,dwmac-<ip_version>", "snps,dwmac" For backwards compatibility: "st,spear600-gmac" is also supported. Previously, when specifying "snps,dwmac-4.10a", "snps,dwmac" as your compatible string, plat_stmmacenet_data would have both has_gmac and has_gmac4 set. This would lead to stmmac_hw_init calling dwmac1000_setup rather than dwmac4_setup, resulting in a non-functional driver. This happened since the check for has_gmac is done before the check for has_gmac4. However, the order should not matter, so it does not make sense to have both set. If something is valid for both, you should do as the stmmac_interrupt does: if (priv->plat->has_gmac || priv->plat->has_gmac4) ... The places where it was obvious that the author actually meant if (has_gmac || has_gmac4) rather than if (has_gmac) has been updated. Signed-off-by:
