Revision 9f78c607600ce4f2a952560de26534715236f612 authored by Roja Rani Yarubandi on 25 May 2021, 13:10:50 UTC, committed by Wolfram Sang on 04 June 2021, 20:32:39 UTC
If the hardware is still accessing memory after SMMU translation
is disabled (as part of smmu shutdown callback), then the
IOVAs (I/O virtual address) which it was using will go on the bus
as the physical addresses which will result in unknown crashes
like NoC/interconnect errors.
So, implement shutdown callback for i2c driver to suspend the bus
during system "reboot" or "shutdown".
