We need to split the START trigger command into two commands because some components have a long delay inside their START handling. This patch introduces two new trigger commands: PRE_START and PRE_RELEASE and a new state PRE_ACTIVE to prepare for that split. Signed-off-by: Guennadi Liakhovetski <[email protected]>
Some DAI drivers have to perform additional preparatory operations before START and RELEASE triggers, pass PRE_* triggers down to them for that purpose. Signed-off-by: Guennadi Liakhovetski <[email protected]>
The SSP trigger handler has a potentially long delay when processing START and RELEASE triggers. Split off an early start trigger to extract that delay out of the SSP driver into the trigger state machine. Signed-off-by: Guennadi Liakhovetski <[email protected]>
Some DAI devices need a delay between their PRE_START and START trigger commands, and similarly between PRE_RELEASE and RELEASE. Add a DAI driver operation to get that delay time and use it between the two commands. Signed-off-by: Guennadi Liakhovetski <[email protected]>
Implement BCLK initialisation delay using the .get_init_delay() operation. Signed-off-by: Guennadi Liakhovetski <[email protected]>
