Hi, This series adds the DT binding and the driver for loading and booting the DSP devices present on various Keystone2 SoC families. The current series supports the 66AK2H/K, 66AK2L and 66AK2E SoC families. Support for the remaining 66AK2G SoC family will be added later as it is awaiting the dependent clock and reset drivers to be merged into mainline. Supported features include basic load/boot using DSP internal memory regions and error recovery. IPC based on the virtio-rpmsg transport with vrings in external DDR memory and interrupts supported through MMRs. The DTS nodes will be posted separately once the binding is accepted. The virtio-rpmsg based IPC stack would require some support in the virtio_rpmsg driver (first 2 patches from Loic's "virtio_rpmsg: make rpmsg channel configurable" series [1] to begin with) if using CMA pools from HighMem area. regards Suman [1] https://lkml.org/lkml/2017/3/28/349 Andrew F.
