Detailed Description

struct s5p_mfc_dev - The struct containing driver internal parameters.

: v4l2_device : video device for decoding : video device for encoding : platform device : child device of the left memory bank (0) : child device of the right memory bank (1) : base address of the MFC hw registers : irq resource : control framework handler for decoding : control framework handler for encoding : power management control : MFC hardware variant information : couter of active MFC instances : lock for operations on videobuf2 queues : lock for changing/checking if a context is ready to be processed : lock for video_device : variable used by the waitqueue : type of last interrupt : error number for last interrupt : waitqueue for waiting for completion of device commands : size of firmware : address of the beggining of bank 1 memory : address of the beggining of bank 2 memory : used for hardware locking : array of driver contexts : number of the currently running context : used to mark which contexts are waiting for hardware : counter for the watchdog : workqueue for the watchdog : worker for the watchdog : videobuf2 allocator contexts for two memory banks : flag set when entering suspend : common context memory (MFCv6) : hardware error code from which warnings start : ops structure holding HW operation function pointers : cmd structure holding HW commands function pointers
