The new interfaces are meant to gradually replace the existing Gpio_session interface. - Each session refers to a single pin. - The session types distiguish the direction of the signal as input or output. - Pin coordinates can be selected via session labels. - GPIO interrupts are covered by the regular IRQ session interface. The interfaces are accompanied by framework utilities and interfaces: - os/pin_driver.h - pin_control_session/component.h - pin_state_session/component.h These headers relieve GPIO drivers from implementing boilerplate code by providing device-agnostic portions. The A64 pio driver serves as reference for using those utilities. https://github.com/nfeske/genode-allwinner/tree/master/src/drivers/pin/a64 Fixes #4315 |
