Hello!
Here's a set of 3 patches against DaveM's 'net-next.git' repo. They (gradually)
add R8A77980 GEther support to the 'sh_eth' driver, starting with couple new
register bits/values introduced with this chip, and ending with adding a new
'struct sh_eth_cpu_data' instance connected to the new DT "compatible" prop
value...
[1/1] sh_eth: add RGMII support
[2/3] sh_eth: add EDMR.NBST support
[3/3] sh_eth: add R8A77980 support
