Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

ethernet@1101c000: Unevaluated properties are not allowed ('clk_csr' was unexpected)

'clk_csr' properity is parsed in driver, but it is not documented in
bingings for now. We will push a patch to describe 'clk_csr' in
snps,dwmac.yaml file in next version patches.

That's not what your driver change is saying. They are the same or
compatible according to your patch #1.
