Subject: [PATCH] i3c: mctp: workaround for wrong DCR value
|
||
|
|
|
||
|
|
In GNR A0 there is an issue about DCR value. I3C MNG IP in GNR A0
|
||
|
|
introduces itself with DCR=0xC9. Adding this value to allow MCTP over
|
||
|
|
I3C driver to be loaded in this case as well.
|
||
|
|
Issue will be fixed in GNR B0.
