Subject: [PATCH v3 0/2] Add gpio driver support for Realtek DHC SoCs
Date:   Thu, 7 Dec 2023 18:07:21 +0800

Precedence: bulk

These patches add the bindings and the gpio driver for Realtek
DHC(Digital Home Center) RTD SoCs, including RTD1295, RTD1395,
RTD1619, RTD1319, RTD1619B, RTD1319D and RTD1315E.

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.
