This patchset adds a driver support for Cadence GPIO controller.
Number of supported lines is configurable. The driver initializes all pins as inputs in probe(). Currently it only supports level-sensitive interrupts.
The interrupts controller was tested with I2C and SPI IPs acting as interrupt sources.
Changes since V1: Switched to generic GPIO infrastructure. Redesigned interrupts, now uses chained irqchip. Drop support for edge-sensitive interrupts. Restore bypass settings at unexport/remove.
