2022-09-26hwmon: w83627hf: Reorder symbols to get rid of a few forward declarationsUwe Kleine-König
Declarations for static symbols are useless code repetition (unless there are cyclic dependencies). Reorder some functions and variables which allows to get rid of 7 forward declarations.

2022-09-25hwmon: (pwm-fan) Switch regulator dynamicallyAlexander Stein
This adds the enable attribute which is used to select if zero PWM duty means to switch off regulator and PWM or to keep them enabled but at inactive PWM output level. Depending on the select enable mode, turn off the regulator and PWM if the PWM duty is zero, or keep them enabled. This is especially important for fan using inverted PWM signal polarity. Having regulator supplied and PWM disabled, some PWM controllers provide the active, rather than inactive signal. With this change the shutdown as well as suspend/resume paths require modifcations as well.

2022-09-19hwmon: (aspeed-pwm-tacho) Add dependency on ARCH_ASPEEDPeter Robinson
The SENSORS_ASPEED is part of the Aspeed silicon so it makes sense to depend on ARCH_ASPEED and for compile testing. Signed-off-by: Peter Robinson <pbrobinson@gmail.com> Link: https://lore.kernel.org/r/20220916120936.372591-1-pbrobinson@gmail.com Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2022-09-19hwmon: (mr75203) modify the temperature equation according to series 5 datasheetEliav Farber
Modify the equation and coefficients used to convert the digital output to temperature according to series 5 of the Moortec Embedded Temperature Sensor (METS) datasheet: T = G + H * (n / cal5 - 0.5) + J * F Where: *) G = 60, H = 200, cal5 = 4094, J = -0.1. *) F = frequency clock in MHz. *) n is the digital output. In code, the G, H and J coefficients are multiplied by a factor of 1000 to get the temperature in milli-Celsius. Final result is clamped in case it exceeds min/max thresholds. Change is done since it is unclear where the current equation and coefficients came from.

2022-09-19hwmon: (mr75203) add VM pre-scaler x2 supportEliav Farber
Add support for mr76006 pre-scaler which provides divide-by-2 scaling of the input voltage, so that it can be presented to the VM for measurement within its range (the VM input range is limited from -0.1V to 1V). The driver reads from the device-tree all the channels that use the mr76006 pre-scaler and multiplies the voltage result by a factor of 2, to represent to the user with the actual voltage input source. Channels that are not in the device-tree are multiplied by a factor of 1.

2022-09-19hwmon: (mr75203) add VM active channel supportEliav Farber
Add active channel support per voltage monitor. The number of active channels is read from the device-tree. When absent in device-tree, all channels are assumed to be used. This shall be useful to expose sysfs only for inputs that are connected to a voltage source. Setting number of active channels to 0, means that entire VM sensor is not used.

2022-09-19hwmon: (emc2305) Remove unnecessary range checkGuenter Roeck
Static analyzers report: drivers/hwmon/emc2305.c:194 emc2305_set_cur_state() warn: impossible condition '(val > 255) => (0-255 > 255)' 'val' is u8 and thus can never be larger than 255. In theory the operation calculating 'val' could result in a value larger than 255, but this won't happen because its parameter has already been range checked and it is guaranteed that the result never exceeds 255. Remove the unnecessary value check. Cc: Michael Shych <michaelsh@nvidia.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
