Subject: [PATCH 07/13] sandbox: use nvmem-reboot-mode instead of syscon-reboot-mode
Date: Sat, 19 Jun 2021 05:45:10 +0200	[thread overview]
Message-ID: <20210619034516.6737-8-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210619034516.6737-1-a.fatoum@pengutronix.de>

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.
