Bit 0, 5, and 6 in the status register are reserved and, if set, do not indicate an alarm. Bit 7 is the 'busy' bit and also does not indicate an alarm. Mask the non-alarm bits to avoid reporting them to userspace. Cc: Tzung-Bi Shih <tzungbi@kernel.org> Reviewed-by:

Module test code reports underflows when writing sensor limits. temp2_min: Suspected underflow: [min=-77000, read 101000, written -2147483648] temp2_max: Suspected underflow: [min=-77000, read 101000, written -2147483648] temp2_crit: Suspected underflow: [min=-77000, read 101000, written -2147483648] Clamp temperature ranges when writing limits to fix the problem. While at it, use sign_extend32() when reading temperatures to make the code easier to understand. Reviewed-by:

In the MAX6581 datasheet Revision 0 to 3, the local channel overtemperature status is reported in bit 6 of register 0x45, and the overtemperature status for remote channel 7 is reported in bit 7. In Revision 4 and later, the local channel overtemperature status is reported in bit 7, and the remote channel 7 overtemperature status is reported in bit 6. A real chip was found to match the functionality documented in Revision 4 and later. The code was fixed with commit 1ea3fd1e ("hwmon: (max6697) Fix swapped temp{1,8} critical alarms"). At that time it looked like this was an original bug. It only turned out later that the problem was the result of incorrect information in the chip datasheet. Document the discrepancy to avoid confusion caused by old versions of the datasheet. Cc: Tzung-Bi Shih <tzungbi@kernel.org> Reviewed-by:

By default the PWM duty cycle in hardware is 100%. On some systems this can cause unwanted fan noise. Add the ability to specify the fan connections and initial state of the PWMs via device properties. Signed-off-by:

Chips reporting overcurrent alarms report it in the second alarm register. That means the second alarm register has to be read, even if the chip only supports 8 or fewer ADC channels. MAX16067 and MAX16068 report undervoltage and overvoltage alarms in separate registers. Fold register contents together to report both with the existing alarm attribute. This requires actually storing the chip type in struct max16065_data. Rename the variable 'chip' to match the variable name used in the probe function. Reviewed-by:

Writing large limits resulted in overflows as reported by module tests. in0_lcrit: Suspected overflow: [max=5538, read 0, written 2147483647] in0_crit: Suspected overflow: [max=5538, read 0, written 2147483647] in0_min: Suspected overflow: [max=5538, read 0, written 2147483647] Fix the problem by clamping prior to multiplications and the use of DIV_ROUND_CLOSEST, and by using consistent variable types.

The iterated nodes are direct children of the device node, and the `device_for_each_child_node()` macro accounts for child node availability. `fwnode_for_each_available_child_node()` is meant to access the child nodes of an fwnode, and therefore not direct child nodes of the device node. In this case, the child nodes are not required outside the loop, and the scoped version of the macro can be used to remove the repetitive `goto put` pattern. Use `device_for_each_child_node_scoped_scoped()` to indicate device's direct child nodes. Reviewed-by:

Use find_closest() instead of manually coding it to find best update interval. Since find_closest() uses rounding to find the best match, the resulting update interval will now reflect the update interval that is closest to the requested value, not the value that is lower or equal to the requested value.
