LM78 insmod parameters and better detection
Supported insmod parameters: ignore, ignore_range probe, probe_range force, force_lm78, force_lm78j, force_lm79 force* overrules ignore* overrules probe* The *_range parameters need three elements for each specification: bus,start_addr,end_addr The address ranges are inclusive. The other parameters need two elements for each specification: bus,addr In each case, '-1' stands for 'any I2C bus', and 9191 stands for 'the ISA bus' (Bonus question: who can figure out why I choose 9191?) In each case, just append if you want several specification, for example: insmod lm78 probe=9191,0x2a0,1,0x56 force_* does no detection, not even chip detection; it blindly assumes you know what you are doing. plain force does the chip detection, but nothing else; but it can still fail if the register read-out does not match a chip type. Detection is done in exactly the same way as sensors-detect, except that only the range 0x20-0x2f is examined by default. This needs to be synchronized somehow with the detect script. I would rather scan the whole I2C address range, but with those clueless PIIX4 hangs when clock chips are read, that would simply give too much trouble. The detect script has slightly better ISA detection now, too. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@325 7894878c-1315-0410-8ee3-d5d059ff63e0
