[PATCH 07/13] sandbox: use nvmem-reboot-mode instead of syscon-reboot-mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We have some syscon-reboot-mode users in tree, but no nvmem-reboot-mode
yet. Use the new nvmem-cells binding to remedy this. Added benefit is
that we no longer access unpartitioned space; The reboot mode is now
clearly described in the device tree.
