That will also unblock my PRUSS. If you can add the data to others as well, it will help in easier migration of the individual drivers, otherwise the ti-sysc interconnect, hwmod, and hwmod reset data combinations will all have to be supported in code. regards Suman > > I've been testing the reset handling logic with OMAP remoteproc > driver which has been converted to use generic reset framework.

Ok, so you are saying you would need the PRM data for am4 in addition? I can generate that one also. -Tero > > regards > Suman > >> >> I've been testing the reset handling logic with OMAP remoteproc >> driver which has been converted to use generic reset framework.

Almost all of the active remoteprocs will be covered by these. OMAP3 ISP driver is also fully upstream, so we would have to manage its legacy compatibility. regards Suman > > -Tero > >> >> regards >> Suman >> >>> >>> I've been testing the reset handling logic with OMAP remoteproc >>> driver which has been converted to use generic reset framework.
