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.
