* gpio: Bulk conversion to generic_handle_domain_irq()Marc Zyngier2021-08-121-2/+2
| | | | | | | | | | | Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq().

* gpio: gpio-hisi: Add HiSilicon GPIO supportLuo Jiaxing2020-12-141-0/+328
This GPIO driver is for HiSilicon's ARM SoC. HiSilicon's GPIO controller support double-edge interrupt and multi-core concurrent access. ACPI table example for this GPIO controller: Device (GPO0) { Name (_HID, "HISI0184") Device (PRTA) { Name (_ADR, Zero) Name (_UID, Zero) Name (_DSD, Package (0x01) { Package (0x02) { "ngpios", 0x20 } }) } } Signed-off-by: Luo Jiaxing <luojiaxing@huawei.com> Link: https://lore.kernel.org/r/1607934255-52544-2-git-send-email-luojiaxing@huawei.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
