This driver is a copy of vt1211, which is almost identical.
The vt1211 is a super i/o chip and the vt8231 is a PCI chip.

provides and API for NVRAM and RTC drivers to sit on top of this. An example
of drivers that uses this API are the Frodo RTC and NVRAM drivers.

Replace VID_FROM_REG() with vid_from_reg() in new sensors_vid.h.
Update library so it can be set in sensors.conf.
Add new documentation. Update mkpatch for new file.

Hello,
I have to use the pcf8574 chip with my I2C interface, however, the pcf8574
drivers in lm-sensors is a bit basic. It supposes the pin P1 is used as an
input and the others pin as outputs.
Attached is a patch which corrects that, providing to files in /proc
interface, one for writting, the other for reading. It also modifies a bit
the driver to support the pcf8574a (it is a pcf8574 with a different address
range), and add a documentation file in doc/chips.
The patch also includes some cosmetic changes in the pcf8591 driver I wrote
previously, that is to say it modify the chip name in some places I had
forgotten to change when I made a copy/paste from another driver.

The following patch does the following:
Fixed bug with not all alarms enabled.
Added ability to read battery voltage
Select temperature sensor type at module load time.
Added setting for Inside Technologies 786LCD board to example config file
I also fixed what looked like a typo in the existing it87 section where
in6_min/max was set twice and in7 was not set. As commented I think
the equation for the negative voltages are wrong but without that motherboard
I can't verify.
With the 786LCD board sensors-detect reports a lm78 which doesn't
exist and a sis5595 which may be part of the SIS630 chip but doesn't
perform the monitoring. The it8705F/SIS950 which is on the board is
reported as a misdetect. I didn't know enough about the various chips
to figure out how to get correct detections.

Ok. I rewrote the patch to support standard (9bit) and enhanced (12bit)
accuracy via the "temp" entry. The "raw" interface is also gone.
There are some quirks needed for the sensors app. It seems that
prog/sensors/chips.c fixes the output to %+3.1f
Thats not good for 12bit mode which gives you 2 decimals and therefor
wrong scaling.
Precision is .062 with 12bit (4 decimal bits) instead of .5 with 9bit (1
decimal bit). That way 2 decimals seem a natural choice.
On the other hand I see no obvious reason not to fix decimals to 1...
I'm lost there -- suggestions anyone?
Another problem is that 12bit is slow and laggy. I don't recommend making
it the default mode.

Leave the files there for now.
Remove old installed sensors.o in kernel/Module.mk.
sensors.c was moved to i2c-proc.c in the i2c package.
i2c-isa.h was appended to i2c.h in the i2c package.
Delete all but the SYSCTL and ALARMS definitions in sensors.h,
as the rest of the file was moved to i2c-proc.h in the i2c package.
Remove #include "i2c-isa.h" lines in all chip drivers and
in bus driver i2c-isa.c.
This all probably breaks mkpatch.

on both platforms). LM87 support is very far along, and should work
for a majority of users, but some minor tweaks are still on the to-do list.

perfectly with the adm1023, but didn't take advantage of it's extra precision
for the remote temp sensor. Now, if an adm1023 is detected, it will.
For example, my adm1021 remote_temp looks like this:
phil@penn phil]$ cat /proc/sys/dev/sensors/adm1021*/remote_temp
60 20 23
My 1023 looks like this:
[root@penn lm_sensors2]# cat /proc/sys/dev/sensors/adm1023-i2c-2-2a/remote_temp
60.125 20.250 1.500 20.875
(Both from the same inserted driver)
Notice the extra 3 digit precision (actually, it's in increments of 0.125).
And, also notice the extra 'limit'. It's actually an offset register.
Right now it's adding 1.5 degrees to the reading for the remote_temp. This
same functionality could easily be done by editing /etc/sensors.conf, but
Analog Devices decided to put it into the chip instead. :')
Things to do: edit the default sensors.conf, and sensors-detect for this
new chip.
Oh, I also added SENSORS_INSMOD_7 into sensors.h. This was the first
driver to need it, apparently.

Set DESTDIR if you want to install at some other place then where you
will run everything from.

* Improved monitoring of /proc directories
Instead of doing:
proc_bus_i2c->fill_inode = &monitor_bus_i2c;
void monitor_bus_i2c(struct inode *inode, int fill)
{
if (fill)
MOD_INC_USE_COUNT;
else
MOD_DEC_USE_COUNT;
}
you can now simply set:
proc_bus_i2c->owner = THIS_MODULE;
and this is just as good!
* An old 2.3 problem seemingly never was resolved yet: instead of using
a *wait_queue directly, you have to use a wait_queue_head_t and
initialize it properly:
#if (LINUX_VERSION_CODE < 0x020301)
static struct wait_queue *pcf_wait = NULL;
#else
static wait_queue_head_t pcf_wait;
#endif
#if (LINUX_VERSION_CODE >= 0x020301)
init_waitqueue_head(&pcf_wait);
#endif
except for this, semantics remain the same (but using a plain
wait_queue_head_t instead of a pointer to a wait_queue)
* I had to change the semantics of sensors_register_entry slightly,
to make the monitoring of /proc/sys/dev/* files possible for kernels
2.3.27 and newer. It now takes an additional parameter, which you
can specify as THIS_MODULE.
* THIS_MODULE is only defined in kernels 2.3.13 and later; added
it to compat.h and the compatibility section of mkpatch.

* Removed several superfluous (struct i2c_client *) casts (they were left
from the time we had separate structs for smbus and isa)
* Removed the internal lists of registered clients
They have not been used for quite some time now, took memory space,
and limited the maximum number of clients that could be registered.
Also removed two small Makefile errors - I am happy I caught them before
the next release!
