2023-10-27misc/led: LED state is set opposite of what is expectedGlenn Miles1-1/+1
Testing of the LED state showed that when the LED polarity was set to GPIO_POLARITY_ACTIVE_LOW and a low logic value was set on the input GPIO of the LED, the LED was being turn off when it was expected to be turned on.

2020-10-26hw/misc/led: Allow connecting from GPIO outputPhilippe Mathieu-Daudé1-1/+16
Some devices expose GPIO lines. Add a GPIO qdev input to our LED device, so we can connect a GPIO output using qdev_connect_gpio_out(). When used with GPIOs, the intensity can only be either minium or maximum. This depends of the polarity of the GPIO (which can be inverted). Declare the GpioPolarity type to model the polarity.

2020-10-26hw/misc/led: Add a LED devicePhilippe Mathieu-Daudé1-0/+142
Add a LED device which can be connected to a GPIO output. They can also be dimmed with PWM devices. For now we do not implement the dimmed mode, but in preparation of a future implementation, we start using the LED intensity. LEDs are limited to a fixed set of colors.
