Subject: [PATCH v7 0/5] Pinctrl: A4: Add pinctrl driver

Add pinctrl driver support for Amloigc A4 SoC

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_X 6 GPIO_ACTIVE_LOW>;

Changes in v7:
- Move gpio-controller property with "#gpio-cells" property
- Link to v6: https://lore.kernel.org/r/20241113-a4_pinctrl-v6-0-35ba2401ee35@amlogic.com

Changes in v6:
- Adjust code formatting and style.
- Remove "#gpio-cells" definition from amlogic,meson-pinctrl-common.yaml
  and add them in all amlogic,meson-pinctrl-XXX.yaml with const: 2, and then
  add amlogic,meson-pinctrl-a4.yaml(copy form  amlogic,meson-pinctrl-a1.yaml) with const: 3.
- Link to v5: https://lore.kernel.org/r/20241112-a4_pinctrl-v5-0-3460ce10c480@amlogic.com

Changes in v5:
- Modify if to switch.
- Dropped parameter combination, bank and offset as independent parameter passing
- Link to v4: https://lore.kernel.org/r/20241101-a4_pinctrl-v4-0-efd98edc3ad4@amlogic.com

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/
