Hi,

rtc is fused out on dra76 and accessing target module
register is causing a boot crash hence disable it.
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?
dra76 & dra71 have rtc fused out. So i did not introduce a new dtsi file
to disable.
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.
For now rtc is disabled only in dra71/dra76. So best disable it in the
evm.dts? Not sure if we need dynamic disabling as we know at DT level
that it is to be disabled.
