-Subject: [PATCH] fix-no-uart-leak-when-gps-off.patch
-
-During the suspend current reduction campaign on suspend I
-forced the GPS UART to be GPIO and to drive 0 into the GPS
-unit so we would not burn current there. On resume it lets
-the pins act as UARTs again. But really, we should do this
-all the time that the GPS unit is off, lest we leak it
-enough power to hold internal state and make trouble.
