[PATCH v2 0/7] Add support for MAX7360

[Mathieu Dubois-Briand <mathieu.dubois-briand@bootlin.com>]

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 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
- Link to v1: https://lore.kernel.org/r/20241219-mdb-max7360-support-v1-0-8e8317584121@bootlin.com
