WebJul 23, 2024 · Here is what we do in the framework of this commit to convert the driver. to using the GPIO-lib-based IRQ-chip interface: 1) IRQ ack, mask and unmask callbacks are locally defined instead of. using the Generic IRQ-chip ones. 2) An irq_chip structure instance is embedded into the dwapb_gpio. private data. Web* @handler_data: per-IRQ data for the irq_chip methods * @affinity: IRQ affinity on SMP. If this is an IPI * related irq, then this is the mask of the * CPUs to which an IPI can be sent. * @effective_affinity: The effective IRQ affinity on SMP as some irq * chips do not allow multi CPU destinations. * A subset of @affinity.

WebDESCRIPTION¶ Set up max. 32 interrupts starting from gc->irq_base. Note, this initializes all interrupts to the primary irq_chip_type and its associated handler. WebFlag to track GPIO chip irq member’s initialization. This flag will make sure GPIO chip irq members are not used before they are initialized. 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. dalyellup pharmacy email
