requesting IRQ ``unsigned long irq_flags`` irq_flags used when requesting IRQ ``const struct scsi_host_template *sht`` scsi_host_template to use when registering the host **Description** After allocating an ATA host and initializing it, most libata LLDs perform three steps to activate the host - start host, request IRQ and register it. This helper takes necessary arguments and performs the three steps in one go. An invalid IRQ skips the IRQ registration and expects the host to have set polling mode on the port. In this case, **irq_handler** should be NULL. On failure, the ports are stopped again and the devres action registered by ata_host_start() is dropped without calling ->host_stop(), so releasing the host resources is left to the caller.

Frozen port is not allowed to perform any operation until the port is thawed, which usually follows a successful reset. ap->ops->freeze() callback can be used for freezing the port hardware-wise (e.g. mask interrupt and stop DMA engine). If a port cannot be frozen hardware-wise, the interrupt handler must ack and clear interrupts unconditionally while the port is frozen.
