Merge tag 'rproc-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull remoteproc updates from Bjorn Andersson:

 - Transition the i.MX8MP DSP remoteproc driver to use the reset
   framework for driving the run/stall reset bits

 - Add support for managing the modem remoteprocessor on the Qualcomm
   MSM8226, MSM8926, and SM8750 platforms
