void (*irq_disable)(struct irq_data *data); void (*irq_unmask)(struct irq_data *data); void (*irq_mask)(struct irq_data *data); }; **Members** ``chip`` GPIO IRQ chip implementation, provided by GPIO driver. ``domain`` Interrupt translation domain; responsible for mapping between GPIO hwirq number and Linux IRQ number. ``fwnode`` Firmware node corresponding to this gpiochip/irqchip, necessary for hierarchical irqdomain support. ``parent_domain`` If non-NULL, will be set as the parent of this GPIO interrupt controller's IRQ domain to establish a hierarchical interrupt domain. The presence of this will activate the hierarchical interrupt support. ``child_to_parent_hwirq`` This callback translates a child hardware IRQ offset to a parent hardware IRQ offset on a hierarchical interrupt chip. The child hardware IRQs correspond to the GPIO index 0..ngpio-1 (see the ngpio field of struct gpio_chip) and the corresponding parent hardware IRQ and type (such as IRQ_TYPE_*) shall be returned by the driver. The driver can calculate this from an offset or using a lookup table or whatever method is best for this chip. Return 0 on successful translation in the driver. If some ranges of hardware IRQs do not have a corresponding parent HWIRQ, return -EINVAL, but also make sure to fill in **valid_mask** and **need_valid_mask** to make these GPIO lines unavailable for translation. ``populate_parent_alloc_arg`` This optional callback allocates and populates the specific struct for the parent's IRQ domain. If this is not specified, then :c:type:`gpiochip_populate_parent_fwspec_twocell` will be used. A four-cell variant named :c:type:`gpiochip_populate_parent_fwspec_fourcell` is also available. ``child_offset_to_irq`` This optional callback is used to translate the child's GPIO line offset on the GPIO chip to an IRQ number for the GPIO to_irq() callback. If this is not specified, then a default callback will be provided that returns the line offset. ``child_irq_domain_ops`` The IRQ domain operations that will be used for this GPIO IRQ chip. If no operations are provided, then default callbacks will be populated to setup the IRQ hierarchy. Some drivers need to supply their own translate function. ``handler`` The IRQ handler to use (often a predefined IRQ core function) for GPIO IRQs, provided by GPIO driver. ``default_type`` Default IRQ triggering type applied during GPIO driver initialization, provided by GPIO driver. ``lock_key`` Per GPIO IRQ chip lockdep class for IRQ lock. ``request_key`` Per GPIO IRQ chip lockdep class for IRQ request. ``parent_handler`` The interrupt handler for the GPIO chip's parent interrupts, may be NULL if the parent interrupts are nested rather than cascaded. ``{unnamed_union}`` anonymous ``parent_handler_data`` If **per_parent_data** is false, **parent_handler_data** is a single pointer used as the data associated with every parent interrupt. ``parent_handler_data_array`` If **per_parent_data** is true, **parent_handler_data_array** is an array of **num_parents** pointers, and is used to associate different data for each parent. This cannot be NULL if **per_parent_data** is true. ``num_parents`` The number of interrupt parents of a GPIO chip. ``parents`` A list of interrupt parents of a GPIO chip. This is owned by the driver, so the core will only reference this list, not modify it. ``map`` A list of interrupt parents for each line of a GPIO chip. ``threaded`` True if set the interrupt handling uses nested threads. ``per_parent_data`` True if parent_handler_data_array describes a **num_parents** sized array to be used as parent data. ``initialized`` Flag to track GPIO chip irq member's initialization. This flag will make sure GPIO chip irq members are not used before they are initialized. ``domain_is_allocated_externally`` True it the irq_domain was allocated outside of gpiolib, in which case gpiolib won't free the irq_domain itself. ``init_hw`` optional routine to initialize hardware before an IRQ chip will be added. This is quite useful when a particular driver wants to clear IRQ related registers in order to avoid undesired events. ``init_valid_mask`` optional routine to initialize **valid_mask**, to be used if not all GPIO lines are valid interrupts. Sometimes some lines just cannot fire interrupts, and this routine, when defined, is passed a bitmap in "valid_mask" and it will have ngpios bits from 0..(ngpios-1) set to "1" as in valid. The callback can then directly set some bits to "0" if they cannot be used for interrupts. ``valid_mask`` If not ``NULL``, holds bitmask of GPIOs which are valid to be included in IRQ domain of the chip. ``first`` Required for static IRQ allocation. If set, irq_domain_create_simple() will allocate and map all IRQs during initialization. ``irq_enable`` Store old irq_chip irq_enable callback ``irq_disable`` Store old irq_chip irq_disable callback ``irq_unmask`` Store old irq_chip irq_unmask callback ``irq_mask`` Store old irq_chip irq_mask callbackh](h)}(h**Definition**::h](hstrong)}(h**Definition**h]h Definition}(hjhhhNhNubah}(h]h ]h"]h$]h&]uh1jhjubh:}(hjhhhNhNubeh}(h]h ]h"]h$]h&]uh1hha/var/lib/git/docbuild/linux/Documentation/driver-api/gpio/index:23: ./include/linux/gpio/driver.hhK4hjubh literal_block)}(hXstruct gpio_irq_chip { struct irq_chip *chip;
