dt-bindings: gpio: fix microchip #interrupt-cells

2026-03-30T08:22:33+00:00

The GPIO controller on PolarFire SoC supports more than one type of interrupt and needs two interrupt cells.

dt-bindings: gpio: Add Tegra264 support

2026-01-29T08:30:54+00:00

Extend the existing Tegra186 GPIO controller device tree bindings with support for the GPIO controller found on Tegra264. The number of pins is slightly different, but the programming model remains the same. Add a new header, include/dt-bindings/gpio/nvidia,tegra264-gpio.h, that defines port IDs as well as the TEGRA264_MAIN_GPIO() helper, both of which are used in conjunction to create a unique specifier for each pin. On Tegra, GPIO wake events are latched and routed via the PMC. Document the standard DT property, wakeup-parent, which is a phandle to the PMC interrupt controller that provides the parent wake interrupt domain for the GPIO controller. If the property is absent the driver falls back to a compatible-based lookup.

dt-bindings: gpio-mmio: Correct opencores GPIO

2026-01-15T15:39:16+00:00

In commit f48b5e8bc2e1 ("dt-bindings: gpio-mmio: Add compatible string for opencores,gpio") we marked opencores,gpio to be allowed with brcm,bcm6345-gpio. This was wrong, opencores,gpio is not compatible with brcm,bcm6345-gpio. It has a different register map and is 8-bit vs Broadcom which is 32-bit. Change opencores,gpio to be a separate compatible string for MMIO GPIO. Also, as this change rewrote the entire enum, I took this opportunity to alphabetically sort the list.

dt-bindings: gpio: add gpio-line-mux controller

2026-01-02T09:59:50+00:00

Add dt-schema for a gpio-line-mux controller which exposes virtual GPIOs for a shared GPIO controlled by a multiplexer, e.g. a gpio-mux. The gpio-line-mux controller is a gpio-controller, thus has mostly the same semantics. However, it requires a mux-control to be specified upon which it will operate.

In FPGA Development boards with GPIOs we use the opencores gpio verilog rtl. This is compatible with the gpio-mmio. Add the compatible string to allow as below.
