Hi,

So for a fix, can we have a separate dra7 something dtsi file
to disable these instead?

Or are there already multiple SoC revisions for the same EVM?

Then in the long run, if there are the same EVMs with multiple
SoC options, the best thing to do is to would be to detect the
SoC type and update the property dynamically to set the features
not available on the booted SoC to status = "disabled". Seems
like that could be done in the ti-sysc driver probe unless needed
earlier.

Regards,

Tony
