* @header: Header and payload
* @header: Header and payload in case of a transmit context.
*
* &struct fw_cdev_iso_packet is used to describe isochronous packet queues.
*
* Use the FW_CDEV_ISO_ macros to fill in @control.
* The @header array is empty in case of receive contexts.
*
* For transmit packets, the header length must be a multiple of 4 and specifies
* the numbers of bytes in @header that will be prepended to the packet's
* payload; these bytes are copied into the kernel and will not be accessed
* after the ioctl has returned. The sy and tag fields are copied to the iso
* packet header (these fields are specified by IEEE 1394a and IEC 61883-1).
* The skip flag specifies that no packet is to be sent in a frame; when using
* this, all other fields except the interrupt flag must be zero.
* Context type %FW_CDEV_ISO_CONTEXT_TRANSMIT:
*
* For receive packets, the header length must be a multiple of the context's
* header size; if the header length is larger than the context's header size,
* multiple packets are queued for this entry. The sy and tag fields are
* ignored. If the sync flag is set, the context drops all packets until
* a packet with a matching sy field is received (the sync value to wait for is
* specified in the &fw_cdev_start_iso structure). The payload length defines
* how many payload bytes can be received for one packet (in addition to payload
* quadlets that have been defined as headers and are stripped and returned in
* the &fw_cdev_event_iso_interrupt structure). If more bytes are received, the
* additional bytes are dropped. If less bytes are received, the remaining
* bytes in this part of the payload buffer will not be written to, not even by
* the next packet, i.e., packets received in consecutive frames will not
* necessarily be consecutive in memory. If an entry has queued multiple
* packets, the payload length is divided equally among them.
* @control.HEADER_LENGTH must be a multiple of 4. It specifies the numbers of
* bytes in @header that will be prepended to the packet's payload. These bytes
* are copied into the kernel and will not be accessed after the ioctl has
* returned.
*
* When a packet with the interrupt flag set has been completed, the
* The @control.SY and TAG fields are copied to the iso packet header. These
* fields are specified by IEEE 1394a and IEC 61883-1.
*
* The @control.SKIP flag specifies that no packet is to be sent in a frame.
* When using this, all other fields except @control.INTERRUPT must be zero.
*
* When a packet with the @control.INTERRUPT flag set has been completed, an
* &fw_cdev_event_iso_interrupt event will be sent.
*
* Context type %FW_CDEV_ISO_CONTEXT_RECEIVE:
*
* @control.HEADER_LENGTH must be a multiple of the context's header_size.
* If the HEADER_LENGTH is larger than the context's header_size, multiple
* packets are queued for this entry.
*
* The @control.SY and TAG fields are ignored.
*
* If the @control.SYNC flag is set, the context drops all packets until a
* packet with a sy field is received which matches &fw_cdev_start_iso.sync.
*
* @control.PAYLOAD_LENGTH defines how many payload bytes can be received for
* one packet (in addition to payload quadlets that have been defined as headers
* and are stripped and returned in the &fw_cdev_event_iso_interrupt structure).
* If more bytes are received, the additional bytes are dropped. If less bytes
* are received, the remaining bytes in this part of the payload buffer will not
* be written to, not even by the next packet. I.e., packets received in
* consecutive frames will not necessarily be consecutive in memory. If an
* entry has queued multiple packets, the PAYLOAD_LENGTH is divided equally
* among them.
*
* When a packet with the @control.INTERRUPT flag set has been completed, an
* &fw_cdev_event_iso_interrupt event will be sent. An entry that has queued
* multiple receive packets is completed when its last packet is completed.
*
* Context type %FW_CDEV_ISO_CONTEXT_RECEIVE_MULTICHANNEL:
*
* Here, &fw_cdev_iso_packet would be more aptly named _iso_buffer_chunk since
* it specifies a chunk of the mmap()'ed buffer, while the number and alignment
* of packets to be placed into the buffer chunk is not known beforehand.
*
* @control.PAYLOAD_LENGTH is the size of the buffer chunk and specifies room
* for header, payload, padding, and trailer bytes of one or more packets.
* It must be a multiple of 4.
*
* @control.HEADER_LENGTH, TAG and SY are ignored. SYNC is treated as described
* for single-channel reception.
*
* When a buffer chunk with the @control.INTERRUPT flag set has been filled
* entirely, an &fw_cdev_event_iso_interrupt_mc event will be sent.

* GPIO expander. The expander will create a block of
* consecutively numbered gpios beginning at the given base,
* with the size of the block depending on the model of the
* expander chip.
* @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
* instead of as an oscillator, increasing the size of the
* GP(I)O pool created by this expander by one. The
* output-only GPO pin will be added at the end of the block.
* @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
* for each IO line in the expander. Setting the bit at
* position n will enable the pull-up for the IO at
* the corresponding offset. For chips with fewer than
* 16 IO pins, high-end bits are ignored.
* @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
* resistor for each IO line in the expander. Setting the
* bit at position n will enable the pull-down for the IO at
* the corresponding offset. For chips with fewer than
* 16 IO pins, high-end bits are ignored.
* @io_open_drain_ena: A bit-mask which enables-or disables open-drain
* operation for each IO line in the expander. Setting the
* bit at position n enables open-drain operation for
* the IO at the corresponding offset. Clearing the bit
* enables regular push-pull operation for that IO.
* For chips with fewer than 16 IO pins, high-end bits
* are ignored.
* @io_polarity: A bit-mask which enables polarity inversion for each IO line
* in the expander. Setting the bit at position n inverts
* the polarity of that IO line, while clearing it results
* in normal polarity. For chips with fewer than 16 IO pins,
* high-end bits are ignored.
* @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
* is connected, via which it reports interrupt events
* across all GPIO lines. This must be a real,
* pre-existing IRQ line.
* Setting this value < 0 disables the irq_chip functionality
* of the driver.
* @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
* IRQ lines will appear. Similarly to gpio_base, the expander
* will create a block of irqs beginning at this number.
* This value is ignored if irq_summary is < 0.
