Wong + +Description +----------- + +This driver implements support for the Analog Devices ADT7473 chip family. + +The LM85 uses the 2-wire interface compatible with the SMBUS 2.0 +specification. Using an analog to digital converter it measures three (3) +temperatures and two (2) voltages. It has three (3) 16-bit counters for +measuring fan speed. There are three (3) PWM outputs that can be used +to control fan speed. + +A sophisticated control system for the PWM outputs is designed into the +LM85 that allows fan speed to be adjusted automatically based on any of the +three temperature sensors. Each PWM output is individually adjustable and +programmable. Once configured, the ADT7473 will adjust the PWM outputs in +response to the measured temperatures without further host intervention. +This feature can also be disabled for manual control of the PWM's. + +Each of the measured inputs (voltage, temperature, fan speed) has +corresponding high/low limit values. The ADT7473 will signal an ALARM if +any measured value exceeds either limit. + +The ADT7473 samples all inputs continuously. The driver will not read +the registers more often than once every other second. Further, +configuration data is only read once per minute. + +Special Features +---------------- + +The ADT7473 have a 10-bit ADC and can therefore measure temperatures +with 0.25 degC resolution. Temperature readings can be configured either +for twos complement format or "Offset 64" format, wherein 63 is subtracted +from the raw value to get the temperature value. + +The Analog Devices datasheet is very detailed and describes a procedure for +determining an optimal configuration for the automatic PWM control. + +Hardware Configurations +----------------------- + +The ADT7473 chips have an optional SMBALERT output that can be used to +signal the chipset in case a limit is exceeded or the temperature sensors +fail.

There are two + * such devices available on the SoC, but it seems that there isn't an + * enumeration class for watchdogs in Linux like there is for RTCs. + * The second is used rather than the first because it uses IRQ 1, + * thereby avoiding all that IRQ 0 problematic nonsense. + * + * I have not tried this driver on a 1480 processor; it might work + * just well enough to really screw things up. + * + * It is a simple timer, and there is an interrupt that is raised the + * first time the timer expires. The second time it expires, the chip + * is reset and there is no way to redirect that NMI. Which could + * be problematic in some cases where this chip is sitting on the HT + * bus and has just taken responsibility for providing a cache block. + * Since the reset can't be redirected to the external reset pin, it is + * possible that other HT connected processors might hang and not reset. + * For Linux, a soft reset would probably be even worse than a hard reset. + * There you have it. + * + * The timer takes 23 bits of a 64 bit register (?) as a count value, + * and decrements the count every microsecond, for a max value of + * 0x7fffff usec or about 8.3ish seconds. + * + * This watchdog borrows some user semantics from the softdog driver, + * in that if you close the fd, it leaves the watchdog running, unless + * you previously wrote a 'V' to the fd, in which case it disables + * the watchdog when you close the fd like some other drivers. + * + * Based on various other watchdog drivers, which are probably all + * loosely based on something Alan Cox wrote years ago. + * + * (c) Copyright 1996 Alan Cox <alan@redhat.com>, All Rights Reserved. + * http://www.redhat.com + * + * This program is free software;
