Just putting the line "options ves1820 pwm=0x53,0x61" in
/etc/modules.conf worked perfectly for me, so I don't
understand why the parameter was removed.
I found this comment in the CVS:
- add back per-device pwm setting support, now done via sysfs attributes
1. Locate the pwm setting
find /sys/|grep "pwm"
/sys/devices/platform/i2c-0/0-0061/pwm
2. Set your desired value
echo "0x5c" > /sys/devices/platform/i2c-0/0-0061/pwm
3. Read the current value
more /sys/devices/platform/i2c-0/0-0061/pwm
Thanks for the investigations, Robert. 8-)
I removed the module parameter because providing a per-card parameter
when loading the module is very unintentional. Additionally, the
number of cards with a ves1820 was restricted by the size of array
that held the per-card informations.
Using sysfs makes it a real per-card parameter.
