The v4l2-subdev infrastructure requires that an initialization call must be issued to all attached sub-devices before normal operation can start. This change satisfies that requirement. Signed-off-by:

When a pvrusb2 driver instance first initializes, we need to be sure to send out a complete state update for everything to all attached modules. The old i2c layer did this by keeping a separate mask of "stale" bits for each attached module - and setting that mask to all stale when that module attaches. But the new sub-device adaptation I've implemented here no longer has per-module stale bits. So instead there's now a global "force dirty" bit that is set upon instance initialization, before the sub-devices are attached. After the first update, this bit is cleared, allowing for normal update-on-dirty behavior. In this manner, we ensure that all sub-devices have been properly synchronized at initialization.

The tuner sub-device isn't going to work very well unless we tell it the correct tuner type to use... Signed-off-by:

The sub-device update mechanism relies on various "dirty" bits in the driver in order to know what pieces of state need to be propagated out to the various sub-devices. But that won't work if the dirty bits are cleared before the update gets a chance to run. This change ensures that the update takes place before the dirty bits are cleared. Signed-off-by:

A sub-device won't successfully attach to our I2C adapter if its class isn't set to zero. Right the class is still set to I2C_CLASS_TV_ANALOG in order to allow the old mechanism to still work. This change temporarily sets the class to zero during the interval when the sub-device attaches. This code will get removed when the old i2c layer is finally removed from the driver. Signed-off-by:

The pvrusb2 driver had previously been using i2c module specific calls to set the sample rate (a long long time ago this was needed). These days it is safe to use a broadcast so let's just broadcast this when communicating audio sample rate to sub-devices. Signed-off-by:

Lay down a foundation whereby it becomes possible to send customized updates to specific sub-devices. (This becomes useful for routing configuration, which is a very sub-device specific operation.) Signed-off-by:

The pvrusb2 driver has a function that reports internal state. It can be accessed from either the debug interface or as the result of a v4l log status request. This change adds information listing sub-devices to the report. Signed-off-by:

Other code may need to treat the video decoder sub-device in a special manner, so this change implements code to recognize when such a sub-device is connected to the driver, does any special processing for it, and notes who the device is for future reference. Signed-off-by:

Tie up loose ends with v4l2-subdev setup. Set attached module's group ID to match our internal ID, emit a few useful messages when sub-devices are dealt with, implement better error legs, and fix an error in the old i2c layer (caused by changes related to the v4l2-subdev work here). Signed-off-by:

In order to keep a sub-device from promiscuously attaching to the pvrusb2 driver, the i2c adapter's class must be cleared. This change clears that class by default. Signed-off-by:

This implements a temporary mechanism to "untrack" an i2c module from the old i2c layer. The v4l2-subdev related code in the driver will use this to remove a sub-device from the old i2c layer. In the end, once the old i2c layer is removed, this will also eventually go away. Signed-off-by:
