The Maxim MAX77759 is a companion PMIC for USB Type-C applications and includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C Port Controller (TCPC), NVMEM, and a GPIO expander. Fuel Gauge and TCPC have separate and independent I2C addresses, register maps, and interrupt lines and are therefore excluded from the MFD core device driver here. The GPIO and NVMEM interfaces are accessed via specific commands to the built-in microprocessor. This driver implements an API that client drivers can use for accessing those.

Adds support for level-triggered interrupts in the PCA953x GPIO expander driver. Previously, the driver only supported edge-triggered interrupts, which could lead to missed events in scenarios where an interrupt condition persists until it is explicitly cleared. By enabling level-triggered interrupts, the driver can now detect and respond to sustained interrupt conditions more reliably.

2025-04-17dt-bindings: gpio: spacemit: add support for K1 SoCYixun Lan
The GPIO controller of K1 support basic functions as input/output, all pins can be used as interrupt which route to one IRQ line, trigger type can be select between rising edge, falling edge, or both. There are four GPIO banks, each consisting of 32 pins.
