This will cause audible clicks and pops when starting or stopping playback. To prevent this a new widget is introduced that controls the DAC power-down bit. This widget is connected to both the DAC and a newly introduced VMID widget. This makes sure that the DAC power-down bit is not set as long as a audio sink is connected to the DAC output. At the same time the PLL and SYSCLK will still be disabled when no playback or capture stream is active.

Currently this is implemented by the driver by registering two virtual controls for each physical control, one for the left mixer and one for the right mixer. Using virtual registers will no longer work when the driver has been converted to regmap. This patch converts the driver to use controls with custom put/get callbacks instead which implement the logic making sure that the physical control is unmuted when either the left or the right control is unmuted.

So instead of allocating a snd_ac97_bus in snd_soc_new_ac97_codec() just use a static one that gets initialized when snd_soc_set_ac97_ops() is called. Also drop the device number parameter from snd_soc_new_ac97_codec(). We currently only support one device per bus and all drivers pass 0 for the device number. And if we should ever support multiple devices per bus it wouldn't be up to individual AC'97 device drivers to pick their number, but rather either the AC'97 adapter driver or the core code will assign them.

This makes the code significantly simpler and also makes it possible to use the AC'97 device in the CODECs probe function. The later will be required to be able to convert the AC'97 CODEC drivers to regmap.

This causes the core to suspend the DAI after the CODEC and resume it before the CODEC so communication to the CODEC is still possible. This is not necessarily something that is specific to AC'97 and can be used by other buses with the same requirement. This patch renames the flag from ac97_control to bus_control to make this explicit. While we are at it also change the type from int to bool.

Doing so creates a clean separation between the AC'97 bus support and the ASoC core.

For those drivers the automatic regmap setup will not work and needs to be done manually, typically from the component/CODEC drivers probe callback.
