^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) * The ADM1025 is a sensor chip made by Analog Devices. It reports up to 6
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) * voltages (including its own power source) and up to two temperatures
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) * (its own plus up to one external one). Voltages are scaled internally
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) * (which is not the common way) with ratios such that the nominal value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) * of each voltage correspond to a register value of 192 (which means a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) * resolution of about 0.5% of the nominal value). Temperature values are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) * reported with a 1 deg resolution and a 3 deg accuracy. Complete
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) * datasheet can be obtained from Analog's website at:

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) * This driver also supports the ADM1025A, which differs from the ADM1025
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) * only in that it has "open-drain VID inputs while the ADM1025 has
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) * on-chip 100k pull-ups on the VID inputs". It doesn't make any
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) * difference for us.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) * This driver also supports the NE1619, a sensor chip made by Philips.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * That chip is similar to the ADM1025A, with a few differences. The only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * difference that matters to us is that the NE1619 has only two possible
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * addresses while the ADM1025A has a third one. Complete datasheet can be

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) * Since the ADM1025 was the first chipset supported by this driver, most
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) * comments will refer to this chipset, but are actually general and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * concern all supported chipsets, unless mentioned otherwise.
