[PATCH v4 0/5] EDAC: Versal NET: Add support for error notification

[Shubhrajyoti Datta]

Adds support for the error notification.
Currently 20 errors has been tested.
This driver is receiving events over rpmsg.
It does not access the registers by itself instead the NMC
reads and sends the info by rpmsg

Also we register the edac once and it reports the errors for all the
events including the 8 DDRMC controllers. So while registering we give
the particulars of the 1st controller.


Changes in v4:
Update the compatible
align the example
Enhance the description for rproc
Update the compatible

Changes in v3:
make remove void

Changes in v2:
- Export the symbols for module compilation
- rename EDAC to memory controller
- update the compatible name
- Add remote proc handle
- Read the data width from the registers
- Remove the dwidth, rank and channel number the same is read from the RpMsg.
- remove reset
- Add the remote proc requests
- remove probe_once
- reorder the rpmsg registration
- the data width , rank and number of channel is read from message.
