I understand now why you need 'pin_status'.
We could compute 'pin_status' and 'pin_changed' in routine
pca9552_update_pin_input() when updating the PCA9552_INPUT0/1
register values and pass
Emit a trace event when a GPIO change its state.
Example booting obmc-phosphor-image:
$ qemu-system-arm -M witherspoon-bmc -trace pca9552_gpio_change
1592690552.687372:pca9552_gpio_change pca1 GPIO id:0 status: 0 -> 1
1592690552.690169:pca9552_gpio_change pca1 GPIO id:1 status: 0 -> 1
