lm_sensors config for ASRock AM1H-ITX / AM1B-ITX

ASRock_AM1H-ITX

#
# ASRock AM1B-ITX / AM1H-ITX
#
# From Nuvoton NCT6776D Data Sheet:
#  - 8-bit Analog to Digital Converter (ADC). Voltage range 0 - 2.048V,
#    8mV LSB (256 steps x 8mV = 2.048V).
#  - Scaling equation: (Value * 8mV * (R1 + R2)) / R2 [1]
#    (*8 already done by driver)
#
# From ASRock A-Tuning Utility config file (AM1BITX.xml):
#  - Vcore: Reg: 0x20, R1: 0, R2: 1
#  - +3.3V: Reg: 0x23, R1: 0x22 (34), R2: 0x22 (34)
#  - +5.0V: Reg: 0x25, R1: 0x14 (20), R2: 0x0A (10)
#  - +12V:  Reg: 0x21, R1: 0x38 (56), R2: 0x0A (10)
#
# From nct6776 driver source code (nct6775.c) [2]
#  - Registers map:
#    0x20, 0x21, 0x22, 0x23, 0x24, 0x25, 0x26, 0x550, 0x551
#    in0   in1   in2   in3   in4   in5   in6   in7    in8
#    Vcore +12V        +3.3V       +5.0V
#
# Sample values read from UEFI and ASRock A-Tuning:
#  - 3.3V: 3.344, 3.360, 3.376
#  - 5V: 5.112, 5.136, 5.160, 5.184
#  - 12V: 11.933, 11.986, 12.038, 12.091, 12.144, 12.197, 12.250
