* @ volume : audio volume V4L2 control ( non - cx2583x devices only )
* @ mute : audio mute V4L2 control ( non - cx2583x devices only )
* @ pvr150_workaround : whether we enable workaround for Hauppauge PVR150
* hardware bug ( audio dropping out )

* this mode gets turned on when the bridge driver calls
* cx25840 subdevice init core op
* @ radio : set if we are currently in the radio mode , otherwise
* the current mode is non - radio ( that is , video )
* @ std : currently set video standard
* @ vid_input : currently set video input
* @ vid_config : currently set video output configuration
* only used in the generic mode
* @ aud_input : currently set audio input
* @ audclk_freq : currently set audio sample rate
* @ audmode : currently set audio mode ( when in non - radio mode )
* @ vbi_line_offset : vbi line number offset
* @ id : exact device model
* @ rev : raw device id read from the chip
* @ is_initialized : whether we have already loaded firmware into the chip
* and initialized it
* @ vbi_regs_offset : offset of vbi regs
* @ fw_wait : wait queue to wake an initialization function up when
* firmware loading ( on a separate workqueue ) finishes
* @ fw_work : a work that actually loads the firmware on a separate
* workqueue
* @ ir_state : a pointer to chip IR controller private data
* @ pads : array of supported chip pads ( currently only a stub )
