	Some drivers do I2C bitbanging by keeping the output to 0 and flipping the GPIO direction between input and output (see for example in Linux gpio_set_open_drain_value_commit, in drivers/gpio/gpiolib.c). When the GPIO is set to input, the pull-up resistor brings the output to 1, while when the GPIO is set to output, the output driver brings the output to 0. Implement this for the nRF51 GPIO device model. First, if both input and output are floating, and there is a pull-up or pull-down resistor configured, do not just set s->in, but also make any devices listening on the output qemu_irq receive that value. Second, if the pin is driven both internally (output pin) and externally you don't get a short circuit if both sides drive the pin to the same value.

2019-01-07	hw/gpio/nrf51_gpio: Add nRF51 GPIO peripheral	Steffen Görtz
	This adds a model of the nRF51 GPIO peripheral. Reference Manual: http://infocenter.nordicsemi.com/pdf/nRF51_RM_v3.0.pdf The nRF51 series microcontrollers support up to 32 GPIO pins in various configurations. The pins can be used as input pins with pull-ups or pull-down. Furthermore, three different output driver modes per level are available (disconnected, standard, high-current). The GPIO-Peripheral has a mechanism for detecting level changes which is not featured in this model.
