These modify the corresponding bits in the configuration register. adi,comp-int is a hardware property, because it affects the behavior of the interrupt signal and whatever it is connected to. adi,timeout-enable is a hardware property, because it affects i2c bus operation. Signed-off-by:

Used enums and while loops to replace switch for selecting and getting update interval from conversion rate bits. Divided the write_alarm_val function into 2 functions. The new function is more generic: it can be used not only for alarm writes, but for any kind of writes which require the device to be in shutdown mode. Signed-off-by:

Currently the local variable hum is being divided by a constant and the results is being re-assigned back to hum before the value is being returned to the caller. The assignment to hum is redundant and can be removed.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

After some testing on a Fujitsu Esprimo P720, it turned out that the limit registers are indeed writable and affect the fan control algorithm. This is supported by the datasheet, which says that the fan control functions are based on the limit and parameter registers. Since accessing those registers is very inefficient, the existing regmap cache is used to cache those registers values. Tested on a Fujitsu Esprimo P720. Signed-off-by:

Accessing virtual registers is very inefficient, so pwm map values should be cached when possible, else userspace could effectively do a DOS attack by reading pwm map values in a while loop. Use the regmap cache to cache those values. Tested on a Fujitsu Esprimo P720. Signed-off-by:
