Hello,
this patch series add a new GPIO charlieplex keypad driver.

I have tested the driver on a custom board with a Solidrun RZ/G2LC SOM
with three charlieplex keyboards, all connected thru a a PCA9416 I2C GPIO
expander.

Link: [v1] https://lore.kernel.org/linux-serial/20250924153740.806444-1-hugo@xxxxxxxxxxx/raw

Changes for v2:
- Fix yamllint error for example
- Remove unused debug variable (nkeys)
- Remove support for custom linux,no-autorepeat DT property
- Remove support for custom gpio-activelow DT property

Thank you.
