On NCT6775F, fan readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or 128) to give the readings more range or accuracy; the other chips do not have a fan speed divider. The driver sets the most suitable fan divisor -itself; specifically, it doubles the divider value each time a fan speed reading -returns an invalid value. Some fans might not be present because they share pins +itself; specifically, it increases the divider value each time a fan speed +reading returns an invalid value, and it reduces it if the fan speed reading +is lower than optimal. Some fans might not be present because they share pins with other functions. Voltage sensors (also known as IN sensors) report their values in millivolts. diff --git a/drivers/hwmon/nct6775.c b/drivers/hwmon/nct6775.c index fd0dd15ae4b6..bafcae55e255 100644 --- a/drivers/hwmon/nct6775.c +++ b/drivers/hwmon/nct6775.c @@ -180,6 +180,9 @@ static const u16 NCT6775_REG_IN[] = { #define NCT6775_REG_VBAT 0x5D #define NCT6775_REG_DIODE 0x5E +#define NCT6775_REG_FANDIV1 0x506 +#define NCT6775_REG_FANDIV2 0x507 + static const u16 NCT6775_REG_ALARM[NUM_REG_ALARM] = { 0x459, 0x45A, 0x45B };
