IRQs are currently only enabled during the driver initialization function (i.e: sai_init()). As such, even though they're not needed (i.e: after a TRIGGER_STOP operation) they remain enabled. Fix this by enabling IRQs after during the TRIGGER_START operation and disabling them during the TRIGGER_STOP operation. This change is required by irq chips (i.e: irqsteer) which perform PM operations during irq_enable()/irq_disable(). If interrupts are left enabled all the time that means the irq chip's PM resources might also remain enabled. To make this change possible, the irq will have to be stored inside the SAI's configuration structure. Signed-off-by: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com> |
