Subject: [PATCH V4 3/6] dt-bindings: can: flexcan: add fsl,scu-index property to indicate a resource
Date: Wed, 21 Oct 2020 13:24:34 +0800 [thread overview]
Message-ID: <20201021052437.3763-4-qiangqing.zhang@nxp.com> (raw)
In-Reply-To: <20201021052437.3763-1-qiangqing.zhang@nxp.com>
For SoCs with SCU support, need setup stop mode via SCU firmware,
so this property can help indicate a resource in SCU firmware.
