Hi Michal, Thanks for reviews. I will ping you once driver changes are approved. Or Mathieu can take this in remoteproc tree, either way is fine.

Hi Mathieu, Yes I agree. I think it should be same as of bindings example. However, I will have to test and make sure no impact on driver. I will fix it in next revision. Meanwhile, are you going to review driver changes as well or do you want to wait for next revision ?

Add properties as per new bindings in zynqmp remoteproc node to represent TCM address and size. This patch also adds alternative remoteproc node to represent remoteproc cluster in split mode. By default lockstep mode is enabled and users should disable it before using split mode dts. Both device-tree nodes can't be used simultaneously one of them must be disabled. For zcu102-1.0 and zcu102-1.1 board remoteproc split mode dts node is enabled and lockstep mode dts is disabled.
