drivers uart_nrfx: Break infinite loops for simulation (14bc4aee) · Commits · Wenxi XU / zephyr

While waiting for the UART to be ready in ISR mode, for simulation only, add a tiny delay per iteration of the busy wait loops to allow time to pass. This Z_SPIN_DELAY is an empty macro for any other target than simulation. Signed-off-by:
