Subject: [PATCH RFC v4 0/4] Pinctrl: A4: Add pinctrl driver

Add pinctrl driver support for Amloigc A4 SoC

I want to find out what kind of solution is feasible to
meet the needs of all parties. This RFC verion is one of them.

All of Amogic SoCs GPIO device requirement is met here by
adding GPIO bank definition instead of the pin definition.
Binding header files will no longer be added to future
SoCs's pin devices.

The pinctrl software only adds insterface of of_xlate to support
for transformation without affecting the overall framework and
is compatible with previous drivers.

The code in DTS file is also readable when using GPIO, as below:

reset-gpios = <&gpio AMLOGIC_GPIO(AMLOGIC_GPIO_X, 6) GPIO_ACTIVE_LOW>;

Changes in v4:
- Add interface of of_xlate support.
- Add const for some variable.
- Link to v3: https://lore.kernel.org/r/20241018-a4_pinctrl-v3-0-e76fd1cf01d7@amlogic.com

Changes in v3:
- Remove head file from binding.
- Move GPIO define to file *.c.
- Link to v2: https://lore.kernel.org/r/20241014-a4_pinctrl-v2-0-3e74a65c285e@amlogic.com

Changes in v2:
- Use one marco instead of all pin define.
- Add unit name for dts node.
- Link to v1: https://lore.kernel.org/all/20240611-a4_pinctrl-v1-0-dc487b1977b3@amlogic.com/
