Subject: [PATCH v3 0/2] gpio: Add a driver for Cadence GPIO controller
Date: Tue, 18 Dec 2018 16:10:40 +0000 [thread overview]
Message-ID: <20181218161042.16366-1-jank@cadence.com> (raw)
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 V2:
Added spinlocks in request, free and irq_set_type functions.
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.
