That's what i have in v4.19.x-bone "today" (and > v4.20.x-bone/v5.0.x-bone).. This is the latest series that I posted for pruss remoteproc https://lkml.org/lkml/2019/2/4/677 I have been mostly focussing on remoteproc framework and PRU ethernet driver use case. I see that uio_pruss is important for the bone community. We will need to work together to make sure that it continues to operate when the PRUSS remoteproc stuff gets merged to kernel.org. I will keep you all in cc when I post v3 of the series so you can test uio_pruss.c and review the patches. Meanwhile, I'd like to understand what must be done to ensure uio_pruss.c is supported. We might need to make some changes to uio_pruss.c so that it can understand the device tree node (interrupts, memory regions) and do runtime_pm etc. It will be great if we don't have to make any device tree changes when switching between pruss_remoteproc and uio_pruss drivers. Just unbinding the current driver and binding the alternate driver should work. > > Last i looked at v4.19.x-bone and uio_pruss, you'll need to revert all > uio changes in v4.18.x/v4.19.x/etc..
