Subject: [PATCH v1 3/3] arm64: dts: imx94: Add OCOTP node
Date: Wed, 24 Sep 2025 18:06:25 +0800 [thread overview]
Message-ID: <20250924-imx943-v1-3-0d32d7852ecb@oss.nxp.com> (raw)
In-Reply-To: <20250924-imx943-v1-0-0d32d7852ecb@oss.nxp.com>
From: Alice Guo <alice.guo@nxp.com>
Add the OCOTP controller node to the i.MX94 device tree. This enables
support for accessing eFuse regions on i.MX94 SoCs via the imx-ocotp
driver.
