Honestly, when explaining new functionality like this, it would be lovely to also give an example of the _why_, not just the what. Ie, some concrete example of "this is useful to have the remoteproc continue scanning wireless networks" or whatever. I'm sure there's some actual use-case for this all, but neither the pull request nor the individual commits seem to actually explain that "why", only the "what". I've pulled this, but hope that these kinds of issues can be explained better.. I think a lot of people care more about "why" than some implementation detail "what" cases. Linus

Thank you!
The following changes since commit a38fd8748464831584a19438cbb3082b5a2dab15: Linux 5.12-rc2 (2021-03-05 17:33:41 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc.git tags/rproc-v5.13 for you to fetch changes up to edf696f26855788cdff832ac83319e1f2aafcc90: remoteproc: stm32: add capability to detach (2021-04-14 09:59:21 -0500) ---------------------------------------------------------------- remoteproc updates for v5.13 This adds support to the remoteproc core for detaching Linux from a running remoteproc, e.g. to reboot Linux while leaving the remoteproc running, and it enable this support in the stm32 remoteproc driver. It also introduces a property for memory carveouts to track if they are iomem or system ram, to enable proper handling of the differences. The imx_rproc received a number of fixes and improvements, in particular support for attaching to already running remote processors and i.MX8MQ and i.MX8MM support. The Qualcomm wcss driver gained support for starting and stopping the wireless subsystem on QCS404, when not using the TrustZone-based validator/loader. Finally it brings a few fixes to the TI PRU and to the firmware loader for the Qualcomm modem subsystem drivers. ---------------------------------------------------------------- Arnaud POULIQUEN (1):
