Subject: [PATCH 1/2] dt-bindings: reset: imx8mq: Add _N suffix to IMX8MQ_RESET_MIPI_CSI*_RESET
Date: Tue, 31 Mar 2026 18:13:30 +0800 [thread overview]
Message-ID: <20260331101331.1405588-2-robby.cai@nxp.com> (raw)
In-Reply-To: <20260331101331.1405588-1-robby.cai@nxp.com>
The assert logic of the MIPI CSI reset signals is active-low on i.MX8MQ,
but the existing names do not indicate this explicitly. To improve
consistency and clarity, append the _N suffix to all
IMX8MQ_RESET_MIPI_CSI*_RESET definitions. The deprecated
IMX8MQ_RESET_MIPI_CSI*_RESET versions remain temporarily for DT ABI
compatibility and will be removed at an appropriate time in the future.
