The TS-7970 includes 3 channels of current-loop sensing ADC that can sample a 4-20mA current loop at about 2/3 samples per second. Note, these ADC cannot be used for voltage sensing. These are accessed using the tsmicroctl utility: 

root@ts-imx6:# tsmicroctl --info
VDD_ARM_CAP=1216
VDD_HIGH_CAP=2618
VDD_SOC_CAP=1246
VDD_ARM=1456
SILAB_P10=0x39B
SILAB_P11=0x0
SILAB_P12=0x0
VIN=12241
V5_A=5207
V3P1=3276
DDR_1P5V=1571
V1P8=1894
V1P2=1262
RAM_VREF=783
V3P3=3543
SILABREV=1
SILAB_P10_UA=21472
SILAB_P11_UA=0
SILAB_P12_UA=0

The other samples are the various voltages on the board. The terminal block ADC values are returned with SILAB_Pnn and SILAB_Pnn_UA. These include both raw and microamp values.
