		Maxim MAX7360 GPIO controller, in MAX7360 chipset
		https://www.analog.com/en/products/max7360.html

		The device provides two series of GPIOs, referred here as GPIOs and GPOs.

		PORT0 to PORT7 pins can be used as GPIOs, with support for interrupts and
		constant-current mode. These pins will also be used by the rotary encoder and
		PWM functionalities.

		COL2 to COL7 pins can be used as GPOs, there is no input capability. COL pins
		will be partitioned, with the first pins being affected to the keypad
		functionality and the last ones as GPOs.
