Delete the icspll driver. It was rather useless, not built by default,
supposedly dangerous, and has nothing to do with sensors. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@4197 7894878c-1315-0410-8ee3-d5d059ff63e0

WARNING: THE CURRENT DRIVER SIMPLY DOES NOT WORK. DO NOT USE.
|
||||
|
||||
ICSPLL Driver
|
||||
-------------
|
||||
This is a clock chip reader.
|
||||
It requires an SMBus interface chip and a clock chip
|
||||
which supports SMBus block reads.
|
||||
|
||||
Stability
|
||||
---------
|
||||
*** ALPHA - It may hang your SMBus or crash your entire system. ***
|
||||
*** Using this driver with an unsupported chip or configuration ***
|
||||
*** is even more likely to hang your SMBus or crash your system. ***
|
||||
|
||||
|
||||
AUTODETECTION
|
||||
-------------
|
||||
None is possible, these chips do not have ID registers.
|
||||
Read the full part number on your clock chip and read this
|
||||
documentation before insmod'ing the icspll module.
|
||||
|
||||
|
||||
CHIPS SUPPORTED
|
||||
---------------
|
||||
This driver will only work on clock chips that support the SMBus
|
||||
block read, which includes a length byte.
|
||||
The clock chip must be at address 0x69.
|
||||
|
||||
According to ICS, this includes the following chips:
|
||||
ICS9148-xx (xx > 20) with a serial interface
|
||||
ICS9248-xx (all xx) with a serial interface
|
||||
|
||||
Other ICS chips DO NOT support SMBus block reads.
|
||||
Not all 9148/9248 ICS chips have a serial interface.
|
||||
See http://www.icst.com to get the data sheet for your clock
|
||||
chip.
|
||||
|
||||
You must have a piix4 or a ali15x3 chip to have this work.
|
||||
Other bridge chips like the via support I2C
|
||||
but not SMBus-style block reads.
|
||||
|
||||
Writes are not supported.
|
||||
|
||||
Partial list of supported chips:
|
||||
ICS:
|
||||
9148-32, 9248-81
|
||||
PLL:
|
||||
none?
|
||||
|
||||
|
||||
CHIPS NOT SUPPORTED
|
||||
-------------------
|
||||
Other ICS chips and PhaseLink Labs (PLL) chips ( http://www.phaselink.com )
|
||||
have an I2C serial interface that is not compatible
|
||||
with SMBus block reads because they do not output a length byte.
|
||||
However because of a lack of block read support in the I2C package,
|
||||
this driver won't work with native I2C systems (like the via)
|
||||
at the moment.
|
||||
|
||||
There may be some PLL chips that support the SMBus length byte,
|
||||
who knows.
|
||||
|
||||
These chips are compatible with SMBus writes which is why
|
||||
motherboard designers put them on the SMBus, so that the BIOS
|
||||
can configure them.
|
||||
But this driver will not support write-only chips.
|
||||
|
||||
Partial list of unsupported chips:
|
||||
ICS:
|
||||
9148-02, 9148B-04, 9148-08, 9150-01, 9150-04, 9150-11
|
||||
PLL:
|
||||
52C64-05, 52C64-25, 52C65-02, 52C66-01, 52C66-03, 52C66-10,
|
||||
52C66-11, 52C66-28, 52C66-29, 52C66-31, 52C66-38, 52C66-39,
|
||||
52C68-02, 52C68-04, 52C69-13, 52C69-15
|
||||
|
||||
|
||||
|
||||
/PROC ENTRY
|
||||
-----------
|
||||
These chips have up to 7 registers.
|
||||
They will appear as 7 decimal values when you cat
|
||||
/proc/sys/dev/sensors/icspll-i2c-*-69/reg0-6.
|
||||
|
||||
|
||||
RESULTS
|
||||
-------
|
||||
If you try this on a supported configuration,
|
||||
please report your clock chip, your SMBus chip
|
||||
(piix4 or ali15x3), and the results of
|
||||
'cat /proc/sys/dev/sensors/icspll-i2c-*-69/reg0-6'
|
||||
|
||||
|
||||
TO DO
|
||||
-----
|
||||
Add a chip= parameter so that you know what chip it is.
|
||||
Put more entries in /proc for the individual fields in the registers.
|
||||
Native I2C support.
