This series implements a set of drivers allowing to support the Maxim
Integrated MAX7360 device.

The MAX7360 is an I2C key-switch and led controller, with following
functionalities:
- Keypad controller for a key matrix of up to 8 rows and 8 columns.
- Rotary encoder support, for a single rotary encoder.
- Up to 8 PWM outputs.
- Up to 8 GPIOs with support for interrupts and 6 GPOs.

Chipset pins are shared between all functionalities, so all cannot be
used at the same time.

Changes in v3:
- Fix MFD device tree binding to add gpio child nodes.
- Fix various small issues in device tree bindings.
- Add missing line returns in error messages.
- Use dev_err_probe() when possible.
- Link to v2: https://lore.kernel.org/r/20241223-mdb-max7360-support-v2-0-37a8d22c36ed@bootlin.com

Changes in v2:
- Removing device tree subnodes for keypad, rotary encoder and pwm
  functionalities.
- Fixed dt-bindings syntax and naming.
- Fixed missing handling of requested period in PWM driver.
- Cleanup of the code
