This series introduces pinctrl support for the Realtek RTD1625 SoC and adds device
nodes for the platform.
In addition to the new SoC support, this series improves the common Realtek pinctrl
library by:
1. Cleaning up license strings and correcting grammar error in error messages.
2. Simplifying error handling in probe() and switching to devm functions.
3. Adding support for slew rate, input voltage parameters, and system
suspend/resume.
4. Fixing return values for unsupported configurations to ensure proper interaction
with gpiolib.
5. Introducing the generic 'input-voltage-microvolt' property to pincfg and
pinconf-generic.
6. Refactoring existing properties (renaming 'realtek,duty-cycle') to improve
clarity.
Best regards,
Yu-Chun Lin

Changes in v2:
- Add relevant mailing lists to CC.
- Add a grammar fix in error messages.
- Move the "support system suspend and resume" patch after the fix patches.
- Introduce the generic 'input-voltage-microvolt' property.
- Add patches for renaming property 'realtek,duty-cycle' to 'realtek,pulse-width-adjust'.
- Improve realtek,rtd1625-pinctrl.yaml description and properties.
- Add RTD1625 pinctrl device nodes to the DTS.
