@geeksville eink TODO:
enable reset as a button
fix battery pin usage
drive TCXO DIO3 enable high whenever we want the clock
use PIN_GPS_WAKE to sleep the GPS
use tp_ser_io as a button, it goes high when pressed
button not working
get pps blinking on second board
clean up eink drawing to not have the nasty timeout hack
put eink to sleep when we think the screen is off
enable flash on spi0, share chip selects on spi1.

feedback to ttgo:
are D10 and D8 backwards on the GPS schematic? gps comms no work?
leds don't work?
use pcf8563 part for waking CPU? or remove it
the mx25 flash chip is great!
