config VIDEO_PVRUSB2
tristate "Hauppauge WinTV-PVR USB2 support"
depends on VIDEO_V4L2 && I2C
select VIDEO_TUNER
select VIDEO_TVEEPROM
select VIDEO_CX2341X
select VIDEO_SAA711X
select VIDEO_CX25840
select VIDEO_MSP3400
select VIDEO_WM8775
select VIDEO_CS53L32A
---help---
This is a video4linux driver for Conexant 23416 based
usb2 personal video recorder devices.
To compile this driver as a module, choose M here: the
module will be called pvrusb2
config VIDEO_PVRUSB2_SYSFS
bool "pvrusb2 sysfs support"
default y
depends on VIDEO_PVRUSB2 && SYSFS
---help---
This option enables the operation of a sysfs based
interface for query and control of the pvrusb2 driver.
This is not generally needed for v4l applications,
although certain applications are optimized to take
advantage of this feature.
If you are in doubt, say Y.
Note: This feature is experimental and subject to change.
config VIDEO_PVRUSB2_DVB
bool "pvrusb2 ATSC/DVB support"
default y
depends on VIDEO_PVRUSB2 && DVB_CORE
select DVB_LGDT330X if MEDIA_SUBDRV_AUTOSELECT
select DVB_S5H1409 if MEDIA_SUBDRV_AUTOSELECT
select DVB_S5H1411 if MEDIA_SUBDRV_AUTOSELECT
select DVB_TDA10048 if MEDIA_SUBDRV_AUTOSELECT
select MEDIA_TUNER_TDA18271 if MEDIA_SUBDRV_AUTOSELECT
select MEDIA_TUNER_SIMPLE if MEDIA_SUBDRV_AUTOSELECT
select MEDIA_TUNER_TDA8290 if MEDIA_SUBDRV_AUTOSELECT
---help---
This option enables a DVB interface for the pvrusb2 driver.
If your device does not support digital television, this
feature will have no affect on the driver's operation.
If you are in doubt, say Y.
config VIDEO_PVRUSB2_DEBUGIFC
bool "pvrusb2 debug interface"
depends on VIDEO_PVRUSB2_SYSFS
---help---
This option enables the inclusion of a debug interface
in the pvrusb2 driver, hosted through sysfs.
You do not need to select this option unless you plan
on debugging the driver or performing a manual firmware
extraction.
If you are in doubt, say N.

The encoder seems to speak entirely using blocks 32 bit words.
In ivtv driver terms, this is a mailbox at MBOX_BASE which we
populate with data and watch what the hardware does with it.
The first word is a set of flags used to control the
transaction, the second word is the command to execute, the
third byte is zero (ivtv driver suggests that this is some
kind of return value), and the fourth byte is a specified
timeout (windows driver always uses 0x00060000 except for one
case when it is zero). All successive words are the argument
words for the command.
First, write out the entire set of words, with the first word
being zero.
Next, write out just the first word again, but set it to
IVTV_MBOX_DRIVER_DONE | IVTV_DRIVER_BUSY this time (which
probably means "go").
Next, read back the return count words. Check the first word,
which should have IVTV_MBOX_FIRMWARE_DONE set. If however
that bit is not set, then the command isn't done so repeat the
read until it is set.
Finally, write out just the first word again, but set it to
0x0 this time (which probably means "idle").
