help with ads1015

[Pierantonio Tabaro <toni.tabaro@xxxxxxxxx>]

Hi,
i have a arm mx28 board with a couple of ads1015,
i have ported the driver from:  
"[PATCH v4] hwmon: Add support for Texas Instruments ADS1015"
to my kernel 2.6.35.3

when i boot the board and probe the two modules hwmon.ko and ads1015.ko nothing 
happens.

with i2cdump i see the chips,i am sure of this because the default values for 
some registers are 0x8583, 0x8000 and 0x7fff. 

sample output for one chip:

root@picomaster ~$ i2cdump 0 0x48 w
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0, address 0x48, mode word
Continue? [Y/n]

08: 0000 8385 0080 ff7f 0000 8385 0080 XXXX 

On sysfs i see this:

root@picomaster ~$ find /sys/ | grep ads1015

I expect to have the inputs value to sysfs, according to source something like 
that: /sys/.../ads1015/in_0_input

Maybe i am missing something, please help me.

Thanks, Pierantonio.
