[PATCH 0/2] Add ICSSG MDIO nodes on AM65x & J721E SoCs

Hi Nishanth,

The following series adds the base MDIO nodes representing the MDIO
sub-module present in each of the ICSSG subsystem. These build on
top of the foundation ICSSG nodes added in v5.13-rc1. Please see
the previous ICSSG foundation series for more details [1]. 

The MDIO nodes would only be used on boards wired for supporting
the ICSSG Ethernet, so in general are expected to be disabled in
all boards where they are not pinned out.

I have added these as "enabled" by default in the base dtsi files,
and have marked it disabled in all the existing board dts files
until we are ready to add in the ICSSG Ethernet functionality.

Note that the bus_freq property throws a warning with W=2, but this
had been a legacy property defined a long back. The davinci-mdio
binding continues to use this.

regards
Suman
