Merge tag 'remoteproc-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc
Pull remoteproc update from Ohad Ben-Cohen:
- Remoteproc Recovery - by Fernando Guzman Lugo
When a remote processor crash is detected, this mechanism will remove
all virtio children devices, wait until their drivers let go, hard
reset the remote processor and reload the firmware (resulting in the
relevant virtio children devices re-added). Essentially the entire
software stack is reset, together with the relevant hardware, so
users don't have to reset the entire phone.
- STE Modem driver is added - by Sjur Brændeland
- OMAP DSP boot address support is added - by Juan Gutierrez
- A handful of fixes/cleanups - Sjur Brændeland, Dan Carpenter, Emil
Goode
