[lm-sensors] [PATCH 05/15] hwmon: (it87) Add support for IT8790E

[Guenter Roeck]

IT8790E is a super-IO chip with three fan tachometers. It is mostly
compatible to IT8728E.

IT8728F, not E. That being said, the IT8728F supports 5 fans, so the
IT8790E seems rather similar to the IT8786E? They are treated exactly
the same AFAICS.

For consistency with the rest of the chip feature descriptions, I'd
write "3 fans".

I'd move this declaration right after IT8786E_DEVID for consistency.

... and 8771, and 8772. I tend to use 8728 as base reference since that is the
first chip which fully supports the new fan control mechanism as well as the new
means of PECI support.

On a side note, did you notice that IT8728F supports up to five pwm controls ?
It doesn't matter much though because pwm4 and pwm5 as simply mapped to pwm1..3
(which one is configurable).
