Hello, This patchset adds GPIO controller support for RDA Micro RDA8810PL SoC. This SoC has 4 GPIO controllers and each handles 32 GPIOs. Except GPIOC, all controllers are capable of generating edge/level interrupts from first 8 GPIO lines. The pinctrl part for this SoC will be added later. This driver has been validated on 96Boards OrangePi i96 board from Shenzhen Xunlong Software Co.,Limited with libgpiod. Thanks, Mani Changes in v3: As per the review by Linus W: * Switched to GPIO MMIO for simplifying the driver * Elaborated the driver commit message * Some misc changes to the driver Changes in v2: As per the review by Bartosz: * Dropped the not implemented gpio_request/free callbacks. * Used device_* helper to fetch ngpios.
