Subject: [PATCH] ARM: dts: imx7s: Add snvs-poweroff support
Date: Thu, 21 Mar 2024 11:31:15 -0300 [thread overview]
Message-ID: <20240321143115.1117060-1-festevam@gmail.com> (raw)
From: Fabio Estevam <festevam@denx.de>
Just like other i.MX devices, i.MX7 also supports using the SNVS
block to poweroff the chip.
Add an entry for it.
