This goes along with input pin modification. In some cases it's easier to know the state of all pins on the GPIO controller before modifying input pins, rather than knowing only the state of input pins. For example over QMP: {"execute":"qom-get","arguments":{ "path":"/machine/soc/gpio[0]", "property":"gpio-pin-level" }} Signed-off-by: Joe Komlodi <komlodi@google.com> --- hw/gpio/npcm7xx_gpio.c | 3 +++ 1 file changed, 3 insertions(+)
