gpio: gpio-ltc4283: Add support for the LTC4283 Swap Controller

2026-06-09T15:30:29+00:00

The LTC4283 device has up to 8 pins that can be configured as GPIOs. Note that PGIO pins are not set as GPIOs by default so if they are configured to be used as GPIOs we need to make sure to initialize them to a sane default. They are set as inputs by default.

gpio: add kunit test cases for the GPIO subsystem

2026-05-26T09:19:54+00:00

Add a module containing kunit test cases for GPIO core. The idea is to use it to test functionalities that can't easily be tested from user-space with kernel selftests or GPIO character device test suites provided by the libgpiod package. For now add test cases that verify software node based lookup and ensure that a GPIO provider unbinding with active consumers does not cause a crash.

gpio: add GPIO controller found on Waveshare DSI TOUCH panels

2026-05-11T07:56:28+00:00

The Waveshare DSI TOUCH family of panels has separate on-board GPIO controller, which controls power supplies to the panel and the touch screen and provides reset pins for both the panel and the touchscreen. Also it provides a simple PWM controller for panel backlight. Add support for this GPIO controller.

gpio: Support ROHM BD72720 gpios

2026-01-13T12:50:08+00:00

The ROHM BD72720 has 6 pins which may be configured as GPIOs. The GPIO1 ... GPIO5 and EPDEN pins. The configuration is done to OTP at the manufacturing, and it can't be read at runtime. The device-tree is required to tell the software which of the pins are used as GPIOs. Keep the pin mapping static regardless the OTP. This way the user-space can always access the BASE+N for GPIO(N+1) (N = 0 to 4), and BASE + 5 for the EPDEN pin. Do this by setting always the number of GPIOs to 6, and by using the valid-mask to invalidate the pins which aren't configured as GPIOs. First two pins can be set to be either input or output by OTP. Direction can't be changed by software. Rest of the pins can be set as outputs only. All of the pins support generating interrupts. Support the Input/Output state getting/setting and the output mode configuration (open-drain/push-pull).
