### BEGIN INIT INFO
# Provides: sensor-setup
# Required-Start: power-on
# Required-Stop:
# Default-Start: S
# Default-Stop:
# Short-Description: Power on micro-server
### END INIT INFO
# Eventually, this will be used to configure the various (mostly
# i2c-based) sensors, once we have a kernel version that supports
# doing this more dynamically.
#
# For now, we're using it to install the lm75 and pmbus module so that it
# can detect the fourth temperature sensor, which is located
# on the uServer, which doesn't get power until power-on executes.
#
# Similarly, the pmbus sensor seems to have an easier time of
# detecting the NCP4200 buck converters after poweron. This has not
# been carefully explored.
modprobe lm75
modprobe pmbus
# Enable the ADC inputs; adc5 - adc9 should be connected to
# 1V, 1.03V, 5V, 3.3V, and 2.5V.
