Data Structures
struct	dataTypeInfo
	This structure contains information about data type and bpp. More...
struct	CsitxDrv_EventObj
	CSITX event object. More...
struct	CsitxDrv_QueObj
	Structure defining the queue object used in queue/dequeue operation. Instead of creating frame objects, this is used so that any other information could be queued/dequeued along with the frame. Already qElem is added to avoid dynamic allocation of Queue nodes. More...
struct	CsitxDrv_ChBufManObj
	Structure to store the buffer management functionality variables for a channel. If serialized multi-channel transitions is disabled through 'serialMultiChanEnable', then following is the association of the Q's freeQ -> per channel and is part of channel buffer management object curQ -> per channel and is part of channel buffer management object doneQ -> per instance and is part of instance buffer management object txQObj -> Queue elements are defined in the channel buffer management object. More...
struct	CsitxDrv_InstBufManObj
	Structure to store the buffer management functionality variables for a instance. More...
struct	CsitxDrv_ChObj
	CSITX Driver Channel Object. More...
struct	CsitxDrv_CslObj
	CSITX CSL-FL instance Object. More...
struct	CsitxDrv_InstObj
	CSITX Driver Instance Object. More...
struct	CsitxDrv_CommonObj

Macros
#define	CSITX_DRV_TRPD_SIZE   ((sizeof(CSL_UdmapTR15) * 2U) + 4U)
	UDMA TR packet descriptor memory. This contains the CSL_UdmapCppi5TRPD + Padding to sizeof(CSL_UdmapTR15) + one Type_15 TR (CSL_UdmapTR15) + one TR response of 4 bytes. Since CSL_UdmapCppi5TRPD is less than CSL_UdmapTR15, size is just two times CSL_UdmapTR15 for alignment. More...
#define	CSITX_DRV_RING_ENTRY_SIZE   (sizeof(uint64_t))
	Size (in bytes) of each ring entry (Size of pointer - 64-bit) More...
#define	CSITX_DRV_RING_MEM_SIZE
	Total ring memory. More...
#define	CSITX_DRV_RING_MEM_SIZE_ALIGN   ((CSITX_DRV_RING_MEM_SIZE + UDMA_CACHELINE_ALIGNMENT) & ~(UDMA_CACHELINE_ALIGNMENT - 1U))
	This ensures every channel memory is aligned. More...
#define	CSITX_DRV_TRPD_SIZE_ALIGN   ((CSITX_DRV_TRPD_SIZE + UDMA_CACHELINE_ALIGNMENT) & ~(UDMA_CACHELINE_ALIGNMENT - 1U))
	This ensures every channel memory is aligned. More...
#define	CSITX_DRV_DEF_PSIL_THREAD_ID   ((uint32_t) 0xFFU)
	PSIL Default thread ID. More...
