The v1.2 mainboard revision changes the routing of several GPIOs to fix bugs and to improve power management. Therefore, it needs an updated device tree. The state of PL6 at boot can be used to distinguish between v1.1 (it can be pulled high) and v1.2 (it will remain low).

# The WiFi module's <tt>CHIP_EN</tt> input (connected to the kill switch) is now pulled down, so the WiFi will turn off reliably when the switch is off.
# The WiFi module's <tt>CHIP_EN</tt> input (connected to the privacy switch) is now pulled down, so the WiFi will turn off reliably when the switch is off.
# PL2 is now connected to the WiFi module's reset pin, allowing the WiFi to be turned off or reset in software.
