We can now drop legacy platform data one interconnect target module at

This breaks wifi on BeagleBone Blue (found via git bisect). In dmesg, I see:
platform 47810000.mmc: Cannot lookup hwmod 'mmc3'
Thanks for letting me know and sorry for breaking it.
How can we fix it?
The warning you pasted above hints that we're still trying to
probe mmc3 using platform data, and that data no longer exists.
Looks like I've completely missed updating the dts file for
mmc3 that is directly on the l3 interconnect instead of l4 like
all the other mmc instances. The same applies for am4 too, and
I've also left some "ti,hwmods" properties around too..
Care to try the following patch and see if it fixes the issue
for you?
Oh I just noticed this needs to be fixed in v5.2, not in v5.3-rc
series. It's best to keep the "ti,hwmods" property still around
as there may be dependencies to ti-sysc driver changes in v5.3-rc
series for dropping it. Below is a more minimal fix to try.
Regards,
Tony
