Data Structures
struct	Dss_IrqParams
	Structure containing DSS interrupt information. Events should be enabled only for available Video Ports and Video Pipes. More...
struct	Dss_RmInfo
	Structure containing resources manager information. This enables display sharing between two different softwares. More...
struct	Dss_SocParams
	DSS SOC parameters. More...
struct	Dss_DctrlOldiParams
	Structure containing OLDI configuration. This structure is used as an argument to IOCTL_DSS_DCTRL_SET_OLDI_PARAMS. More...

Macros
#define	DSS_DCTRL_MAX_NODES   ((uint32_t) 9U)
	Defines maximum number of nodes for allocation including invalid node. More...
#define	DSS_DCTRL_MAX_EDGES   ((uint32_t) 8U)
	Defines maximum number of edges for allocation. This is derived by looking at all possible DSS connections in the SoC. More...
