Change log: v2->v3: 1. Remove generic compatible and use SoC-specific compatible instead. 2. Add the missing descriptions for the rtd_gpio_info structure members. 3. Assign gpio_chip fwnode. v1->v2: 1. Add description for DHC RTD SoCs in the bindings. 2. Revise the compatible names in the bindings. 3. Transitioned from OF API to platform_device API. 4. Use u8 for the offset array within the rtd_gpio_info structure. 5. Record the size of each array within the rtd_gpio_info structure and implement checks to prevent out-of-bounds access. 6. Use GPIOLIB_IRQCHIP helpers to register interrupts. 7. Use dynamic allocation for GPIO base.
