| * irqdomain: Add irq_domain_{push,pop}_irq() functionsDavid Daney2017-08-182-0/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For an already existing irqdomain hierarchy, as might be obtained via a call to pci_enable_msix_range(), a PCI driver wishing to add an additional irqdomain to the hierarchy needs to be able to insert the irqdomain to that already initialized hierarchy. Calling irq_domain_create_hierarchy() allows the new irqdomain to be created, but no existing code allows for initializing the associated irq_data. Add a couple of helper functions (irq_domain_push_irq() and irq_domain_pop_irq()) to initialize the irq_data for the new irqdomain added to an existing hierarchy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Rapid General-Purpose Input and Output with 2 Ports (RGPIO2P) on MX7ULP is similar to GPIO on Vibrid. But unlike Vibrid, the RGPIO2P has an extra Port Data Direction Register (PDDR) used to configure the individual port pins for input or output. We introduce a bool have_paddr with fsl_gpio_soc_data data to distinguish this differences. And we support getting the output status by checking the GPIO direction in PDDR.
