Subject: [PATCH v3 1/6] dt-bindings: firmware: arm,scmi: Add properties for i.MX95 Pinctrl OEM extensions
Date: Sun, 28 Apr 2024 13:07:47 +0800 [thread overview]
Message-ID: <20240428-pinctrl-scmi-oem-v3-v3-1-eda341eb47ed@nxp.com> (raw)
In-Reply-To: <20240428-pinctrl-scmi-oem-v3-v3-0-eda341eb47ed@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
i.MX95 Pinctrl is managed by System Control Management Interface(SCMI)
firmware using OEM extensions. No functions, no groups are provided by
the firmware. To reuse generic properties, add the binding to enable
pinmux, slew-rate, bias-pull-up and etc, under a subnode of '-pins'.
