[v2,0/3] hwmon: (lm85) add LM96000 high freqency pwm support

Hi,

This patch adds support for the PWM frequencies from 22.5 to 30 kHz
available on the LM96000.

It looks like this chip has been supported for a long time, but wasn't
mentioned in the docs (which I have updated).

Also, it has been using the generic 'lm85' prefix, which I have not
changed to avoid breaking userspace or device tree files. AFAICT,
lm85_detect() will only return 'lm85' for LM96000 chips, so it doesn't
look like you can get a bare 'lm85' prefix with any other chips.

I stumbled on to a 10 year old thread discussing a patch which looks
like an early attempt to add support for this chip, which may be of
interest:

Thanks for reviewing,

Jeremy

Changes since v1:
 - replace freq_map_mask with freq_map_size
