Subject: [PATCH v1 3/3] arm64: dts: imx8mp: add ABB spi sensors
Date: Sat, 19 Jul 2025 08:33:54 +0200 [thread overview]
Message-ID: <20250719063355.73111-4-hs@denx.de> (raw)
In-Reply-To: <20250719063355.73111-1-hs@denx.de>
add for the spi busses the ABB sensor trivial compatible
entry, so they can be accessed from userspace.
