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:

This is another step in the v42l-subdev assimilation. This implements various call-outs to sub-devices based on state changes within the pvrusb2 driver. 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:

This introduces some additional isolation in the pvrusb2 from the old i2c layer, a step along the way to separate the driver from that layer and to make it easier to introduce the common v4l2-subdev framework as the eventual replacement. Signed-off-by:

Define a v4l2_device instance in the pvrusb2 driver and initialize / tear it down appropriately. This is a step in the v4l2-subdev adoption effort. Signed-off-by:

This is the first step in the effort to move the pvrusb2 driver over to using the v4l2-subdev framework. This commit involves mainly splitting apart pvrusb2-i2c-core - part of it is the driver's I2C adapter driver and the rest is the old i2c module handling logic. The i2c module handling junk is moved out to pvrusb2-i2c-track and various header references are correspondingly updated. Yes, this patch has a huge pile of checkpatch complaints, but I'm NOT going to fix any of it. Why? First, I'm moving a large chunk of existing code and I'm not going to spend time adjusting it to match someone's idea of coding style. Second, in the end I expect all that moved code to go away by the time the rework is done so wasting time on it now to adhere to the standard is in the end a large waste of time. Signed-off-by:
