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. Lee Jones suggested the whole series goes through MFD subsystem, once all patches got the needed Acks.
