Non-cleared faults in its turn may fail the subsequent page count auto-detection. This patch fixes this problem by calling pmbus_clear_fault_page() for currently set page and calling pmbus_clear_faults() after the page count was detected.

One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).

| * | | hwmon: (core) Add trace events to _attr_show/store functionsNicolin Chen2018-10-111-7/+20

There're people who analyse the relationship of cpufreq, thermal and hwmon (power/voltage/current) using the convenient and timestamped Ftrace outputs, while unlike cpufreq and thermal subsystems the hwmon does not have trace events supported yet. So this patch adds initial trace events for the hwmon core. To call hwmon_attr_base() for aligned attr index numbers, it also moves the function upward. Ftrace outputs: ...: hwmon_attr_show_string: index=2, attr_name=in2_label, val=VDD_5V ...: hwmon_attr_show: index=2, attr_name=in2_input, val=5112 ...: hwmon_attr_show: index=2, attr_name=curr2_input, val=440 Note that the _attr_show and _attr_store functions are tied to the _with_info API. So a hwmon driver requiring the trace events feature should use _with_info API to register a hwmon device.

Each port is used to measure the voltage and current of its input source. The DT binding now has defined bindings for their input sources, so the driver should read these information and handle accordingly. This patch adds a new structure of input source specific information including input source label, shunt resistor value and its connection status. It exposes these labels via in[123]_label sysfs nodes upon available, and also disables those channels where there are no input source being connected. Meanwhile, it also adds in[123]_enable sysfs nodes for users to get control of three channels, and returns -ENODATA code for any sensor read according to hwmon ABI.

| * | | hwmon: (ina3221) Add INA3221_CONFIG to volatile_tableNicolin Chen2018-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MSB (15th bit) of INA3221_CONFIG is a self-clear reset bit. So this register should be added to the volatile_table of the regmap_config. Otherwise, we will see this bit is sticky in the regcache which might accidentally reset the chip when an actual write happens to the register. This might not be a severe bug for the current code line since there's no second place touching the INA3221_CONFIG except the reset routine in the probe().

| * | | hwmon: (pwm-fan) Set fan speed to 0 on suspendThierry Reding2018-10-101-1/+11

However, when support for atomic operations was implemented in the PWM subsystem, only actual changes to the PWM channel are applied during pwm_config(), which means that during after resume from suspend the old settings won't be applied. One possible solution is for the PWM driver to implement its own PM operations such that settings from before suspend get applied on resume. This has the disadvantage of completely ignoring any particular ordering requirements that PWM user drivers might have, so it is best to leave it up to the user drivers to apply the settings that they want at the appropriate time. Another way to solve this would be to read back the current state of the PWM at the time of resume. That way, in case the configuration was lost during suspend, applying the old settings in PWM user drivers would actually get them applied because they differ from the current settings. However, not all PWM drivers support reading the hardware state, and not all hardware may support it. The best workaround at this point seems to be to let PWM user drivers tell the PWM subsystem that the PWM is turned off by, in addition to disabling it, also setting the duty cycle to 0. This causes the resume operation to apply a configuration that is different from the current configuration, resulting in the proper state from before suspend getting restored.

Remove the check as it isn't doing anything currently; if validation of the contents of the data structure was intended by the original author (since this line has been present from the first version of this driver), it can be added in a follow-up patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BIOS developer guides refer to Family 15h Models 60h-6fh and Family 15h Models 70h-7fh. So far the driver only checked for Models 60h and 70h. However, there are now processors with other model numbers in the same families. Example is A10-9620P family 15h model 65h. Follow the developer guides and mask the lower 4 bit of the model number to determine the registers to use for reading temperatures and temperature limits.
