[PATCH RFC 0/3] Pinctrl: Add Amlogic pinctrl driver

[Xianwei Zhao via B4 Relay <devnull+xianwei.zhao.amlogic.com@xxxxxxxxxx>]

Add pinctrl driver support for Amloigc SoCs

Base on the previous discussion,
https://lore.kernel.org/r/20241113-a4_pinctrl-v6-0-35ba2401ee35@xxxxxxxxxxx
The existed meson driver failed to meet the requirement of the current dt-binding.
So we start this new pinctrl driver to solve problem.

The advantage of this version: Once the source file and binding document
are added, adding dts node will be only operation for subsequent Amlogic SoCs
(such as A4, A5).

The code in DTS file is also readable when using GPIO, as below:
reset-gpios = <&gpiob 6 GPIO_ACTIVE_LOW>;
