Subject: [PATCH] i3c: master: drop GETMRL and GETMWL for MNG use case
|
|
|
|
For MNG use case there is no need to send GETMRL and GETMWL because those
|
|
CCCs are not supported by target device. For MNG use case will use
|
|
hardcoded maximum values.
|
|
Moreover there is an issue in ICE1.0 where PEC error counter is bumped up
|
|
in case sending not supported CCC.
