^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) * The LM87 is a sensor chip made by National Semiconductor. It monitors up
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) * to 8 voltages (including its own power source), up to three temperatures
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) * (its own plus up to two external ones) and up to two fans. The default
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) * configuration is 6 voltages, two temperatures and two fans (see below).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) * Voltages are scaled internally with ratios such that the nominal value of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) * each voltage correspond to a register value of 192 (which means a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) * resolution of about 0.5% of the nominal value). Temperature values are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) * reported with a 1 deg resolution and a 3-4 deg accuracy. Complete
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) * datasheet can be obtained from National's website at:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) * http://www.national.com/pf/LM/LM87.html

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * Some functions share pins, so not all functions are available at the same
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * time. Which are depends on the hardware setup. This driver normally
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * assumes that firmware configured the chip correctly. Where this is not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) * the case, platform code must set the I2C client's platform_data to point
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) * to a u8 value to be written to the channel register.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * For reference, here is the list of exclusive functions:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) * - in0+in5 (default) or temp3
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) * - fan1 (default) or in6
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * - fan2 (default) or in7
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) * - VID lines (default) or IRQ lines (not handled by this driver)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) * The LM87 additionally features an analog output, supposedly usable to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) * control the speed of a fan. All new chips use pulse width modulation
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) * instead. The LM87 is the only hardware monitoring chipset I know of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) * which uses amplitude modulation. Be careful when using this feature.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) * This driver also supports the ADM1024, a sensor chip made by Analog
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) * Devices. That chip is fully compatible with the LM87. Complete
