Hi Marek, System Manager which runs on M core sets pin or group configurations. U-Boot sends a SCMI message to System Manager to perform hardware operations. You can refer to the source code for details: https://github.com/nxp-imx/imx-sm. > > +#include "pinctrl-imx.h" > > + > > +#if defined(CONFIG_IMX93) > > Use IS_ENABLED() or CONFIG_IS_ENABLED() > > > +#define DAISY_OFFSET 0x360 > > Why can this offset information not be queried from the firmware interface ? This offset information is not provided by System Manager. DAISY_OFFSET is used to convert the daisy register address in imx95-pinfunc.h for System Manager to use.
