Hi David,
It sounds like we want a solution that
* lives in core code
* doesn't require tuner drivers to save state
* manages hybrid tuners appropriately
* allows for gradual API change-over (no flag day for tuners or
for capture devices)
* has a reasonable

Without this patch, MythTV requires some workarounds to be able to

What does the V4L2 API spec say about tuning frequency being persistent

have that assumption, or is cx231xx wrong to

Tuner standards and frequencies must be persistent. So cx231xx is wrong.
Actually, all V4L2 settings must in general be persistent (there are
some per-filehandle settings when dealing with low-level subdev setups or

This isn't just the cx231xx driver. Almost all USB devices that have

Hmm, it sounds like perhaps changing the standby call in the tuner core
to asynchronously power down the tuner may be the way to go -- ie, when
we tell it to standby, it will do a schedule_work for some 10 seconds
