Does it actually fix it on a clean 5.8-rc kernel? From what I know, the efuse driver cannot probe, because the nemc driver requests the complete memory resource, so the efuse driver's devm_platform_ioremap_resource() fails. I did send a patch to fix this (https://lore.kernel.org/lkml/551a8560261543c1decb1d4d1671ec4b7fa52fdb.1582905653.git.hns@goldelico.com/), but it's hard to have somebody merge it, because nobody maintains drivers/memory/. > Fixes: 19c968222934 ("MIPS: DTS: CI20: make DM9000 Ethernet > controller use NVMEM to find the default MAC address"). That shouldn't be a fix IMHO - the devicetree was updated in one commit, the config should be updated in another. The "bug" here is that it wasn't done right away. > Signed-off-by: 周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com> Btw - when you add a Fixes: tag to fix a commit that is not for the kernel currently in RC phase, you need to Cc linux-stable as well.

The patch I mentioned was merged, so starting from 5.9-rc1 the efuse driver should work. Please resend this patch after 5.9-rc1 then.

The commit 19c968222934 ("MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the default MAC address") add EFUSE node for DM9000 in CI20, however, the EFUSE driver is not selected, which will cause the DM9000 to fail to read the MAC address from EFUSE, causing the following issue: [FAILED] Failed to start Raise network interfaces. Fix this problem by select CONFIG_JZ4780_EFUSE by default in the ci20_defconfig. Fixes: 19c968222934 ("MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the default MAC address").
