Subject: [PATCH 0/4] Enable Remote GPIO over RPMSG on i.MX Platform
Date: Mon, 18 Aug 2025 15:44:16 -0500 [thread overview]
Message-ID: <20250818204420.794554-1-shenwei.wang@nxp.com> (raw)
Support the remote devices on the remote processor via the RPMSG bus on
i.MX platform.
The expected DTS layout structure is following:
cm33: remoteproc-cm33 {
compatible = "fsl,imx8ulp-cm33";
rpmsg {
rpmsg-io-channel {
gpio@0 {
compatible = "fsl,imx-rpmsg-gpio";
reg = <0>;
};
gpio@1 {
compatible = "fsl,imx-rpmsg-gpio";
reg = <1>;
};
...
};
rpmsg-i2c-channel {
i2c@0 {
compatible = "fsl,imx-rpmsg-i2c";
reg = <0>;
};
};
...
};
};
