This series introduces pinctrl support for the Realtek RTD1625 SoC.

Besides the new SoC support, this series improves the common Realtek pinctrl
driver and the generic pinctrl library by:

1. Introducing the generic 'input-threshold-voltage-microvolt' property to pincfg
and pinconf-generic.
2. Improve other Realtek pinctrl bindings's descrption.
3. Adding support for slew rate, input voltage parameters.

I welcome feedback and suggestions.

Best regards,
Yu-Chun Lin

Changes in v4:
- Add a new patch to fix the argument type in rtd_pconf_parse_conf().
- Rename property from "input-voltage-microvolt" to
"input-threshold-voltage-microvolt".
- Update pinconf-generic to reflect the property renaming.
- Add tag from Linus and Conor which received in v3.
