H A Dlm63.c20 * The datasheet isn't very clear about what the tachometer reading is.
114 * For tachometer counts, the LM63 uses 16-bit values.

H A Dmax6650.c184 * Each tachometer counts over an interval given by the "count" get_fan()
230 * Note: this tachometer is completely separate from the tachometers
357 * 2 = Closed loop, RPM for all fans regulated by fan1 tachometer
H A Dg762.c826 * of tachometer pulses per fan revolution.
934 * the fan speed using pulses from fan tachometer.
H A Dit87.c214 * for fan divisors. Later IT8712F revisions must use 16-bit tachometer
2262 * These are the first revisions with 16-bit tachometer support. it87_probe()
H A Ddme1737.c362 * Converts a register value to a TPC multiplier or returns 0 if the tachometer

H A Dthinkpad_acpi.c7497 * the tachometer while the fan controller ramps up
7521 * Main fan tachometer reading (in RPM)
7527 * tachometer as well.
7531 * probably support the tachometer (like the early X models), so
7547 * When bit 0 of EC register 0x31 is zero, the tachometer registers
7549 * is one, the tachometer registers show the speed of the auxiliary
