CDI_RDEV_CFG

#define CDI_RDEV_CFG	(		csi,
			i2c
	)		(((uint32_t)(csi) << (uint32_t)RDEV_CFG_I2C_BITS) | (i2c))

Macro to create root device configuration with the connected CSI port and I2C bus.

Parameters

[in]	csi	The CSI port number defined in NvSiplCapInterfaceType.
[in]	i2c	The I2C bus number defined in DevBlkCDI_I2CPort.

Definition at line 68 of file devblk_cdi.h.

CDI_RDEV_CFG_EX

#define CDI_RDEV_CFG_EX	(		csi,
			i2c,
			disPwrCtrl
	)

Value:

         ((i2c & 0xffU) | \
          ((uint32_t)(csi & 0xffU) << (uint32_t)RDEV_CFG_I2C_BITS) | \
          ((uint32_t)(disPwrCtrl & 1U) << (uint32_t)RDEV_CFG_SLV_BIT))

Extended macro to create root device configuration with the connected CSI port, I2C bus, and an option to disable power control from root device.

Parameters

[in]	csi	The CSI port number defined in NvSiplCapInterfaceType.
[in]	i2c	The I2C bus number defined in DevBlkCDI_I2CPort.
[in]	disPwrCtrl	A flag to disable power control. Value must be 0 (root device turns on power for devices in DevBlkCDIRootDeviceCreate() and turns off power for devices in DevBlkCDIRootDeviceDestroy()) or 1 (root device does not control power for devices in DevBlkCDIRootDeviceCreate() and DevBlkCDIRootDeviceDestroy()). Valid range: [0, 1].

CDI_SLV_RDEV_CFG

#define CDI_SLV_RDEV_CFG	(		csi,
			i2c
	)		((i2c) | ((uint32_t)(csi) << RDEV_CFG_I2C_BITS) | ((uint32_t)(1U) << RDEV_CFG_CSI_BITS))

Macro to create a passive root device configuration with the connected CSI port and I2C bus when the application is run on a passive SoC.

Parameters

[in]	csi	The CSI port number defined in NvSiplCapInterfaceType.
[in]	i2c	The I2C bus number defined in DevBlkCDI_I2CPort.
