This patch proposes to enable kcontrols for siggen type dapm widgets. This will allow triggering the tone generating siggen component and also modifying the run-time attributes such as frequency, amplitude etc. Signed-off-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>
Check if the siggen comp has exactly 1 kcontrol for triggering. Since the kcontrol for the siggen serves as an ON/OFF switch, its max value should be 1. Signed-off-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>
This patch proposes a new IO handler for switch type kcontrols which can be used to trigger components such as siggen or control volume mute functionality. Signed-off-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

…rol IO handler This patch adds the changes to the switch control IO handler to handle the additional steps required to trigger the siggen pipeline based on user input.wq When the user switches the siggen control ON, the IO handler sends the ipc messages required to set up the pcm params and start the pipeline. When the user switches it off, it frees the pcm and resets the pipeline. Signed-off-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

This patchset adds the support for triggering hostless siggen pipelines using the kcontrol associated with the siggen widget. It also proposes a bespoke IO handler for switch type kcontrols
such as those required for triggering the tone component.
This patchset is followed by another series that enables the BE for hostless pipelines.
Tested with:
Minnowboard turbot with RT5651 and Up squared board with HifiBerry DAC+

Please store the config before switching to the tone topology using:
alsactl store -f config.state
And restore after switching to the tone topology with:
alsactl restore -f config.state
v4 changes:
1. minor changes to switch kcontrol IO Handler
2. included the patch to enable kcontrol for siggen widget
