Subject: [PATCH v5 8/9] ARM: nspire: Use syscon-reboot to handle restart
Date: Mon, 23 Jan 2023 15:49:23 -0600 [thread overview]
Message-ID: <20230123214924.27476-9-afd@ti.com> (raw)
In-Reply-To: <20230123214924.27476-1-afd@ti.com>
Writing this bit can be handled by the DT syscon-reboot driver.
Enable that driver and remove the machine_desc version.
