This patch provides a driver for the SCMI pin control protocol which is based on ARM's System Control and Management Interface (SCMI) 3.2. Currently, only the PINCTRL_CONFIG_SET command is implemented.
What is the SCMI provider for this platform ?
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.
Can I use optee-os as a SCMI provider instead ?
+#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.
OK
