It reports up to 6 81da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * voltages (including its own power source) and up to two temperatures 91da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * (its own plus up to one external one). Voltages are scaled internally 101da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * (which is not the common way) with ratios such that the nominal value 111da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * of each voltage correspond to a register value of 192 (which means a 121da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * resolution of about 0.5% of the nominal value). Temperature values are 131da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * reported with a 1 deg resolution and a 3 deg accuracy. Complete 141da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * datasheet can be obtained from Analog's website at: 152b22de5117d6dec44b62c305cb456e5b9a913c95Guenter Roeck * http://www.onsemi.com/PowerSolutions/product.do?id=ADM1025 161da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * 171da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * This driver also supports the ADM1025A, which differs from the ADM1025 181da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * only in that it has "open-drain VID inputs while the ADM1025 has 191da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * on-chip 100k pull-ups on the VID inputs". It doesn't make any 201da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * difference for us. 211da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * 221da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * This driver also supports the NE1619, a sensor chip made by Philips. 231da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * That chip is similar to the ADM1025A, with a few differences. The only 241da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * difference that matters to us is that the NE1619 has only two possible 251da177e4c3f41524e886b7f1b8a0c1fc7321cacLinus Torvalds * addresses while the ADM1025A has a third one.
