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".
