2014-11-11hwmon: (fam15h_power) Fix NB device ID for F16h M30hAravind Gopalakrishnan1-1/+1
F3 device ID is wrongly included in fam15h_power_id_table for F16h M30h. It should be F4 device ID. Fix this. Signed-off-by: Aravind Gopalakrishnan <aravind.gopalakrishnan@amd.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-11-11hwmon: (pwm-fan) Fix suspend/resume behaviorKamil Debski1-3/+10
The state of a PWM output is not clearly defined after resume. Some PWM drivers do not restore the duty cycle upon resume, thus it is necessary to manually restore the correct value. Signed-off-by: Kamil Debski <k.debski@samsung.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-11-11hwmon: (ibmpowernv) Quieten when probing finds no deviceMichael Ellerman1-2/+4
Because we build kernels with drivers built in for many platforms, it's normal for the ibmpowernv driver to be loaded on systems that don't have the appropriate hardware. Currently the driver spams the log with: ibmpowernv ibmpowernv.0: Opal node 'sensors' not found ibmpowernv: Platfrom driver probe failed But there is no error, this machine is not a powernv and doesn't have the hardware. So change the sensors message to dev_dbg(), and only print an error about the probe failing if it's not ENODEV. Also fix the spelling of "Platfrom" and print the actual error value.

On platforms with sizeof(int) < sizeof(long), writing a temperature limit larger than MAXINT will result in unpredictable limit values written to the chip. Avoid auto-conversion from long to int to fix the problem. Voltage limits, fan minimum speed, pwm frequency, pwm ramp rate, and other attributes have the same problem, fix them as well. Zone temperature limits are signed, but were cached as u8, causing unepected values to be reported for negative temperatures.

Avoid auto-conversion from long to int to fix the problem. The hysteresis temperature range depends on the value of data->temp[attr->index], since val is subtracted from it.

Some of it definitely belongs into the ugly code museum. - Consolidation of the timekeeping interface zoo. - A fast NMI safe accessor to clock monotonic for tracing. This is a long standing request to support correlated user/kernel space traces. With proper NTP frequency correction it's also suitable for correlation of traces accross separate machines. - Checkpoint/restart support for timerfd. - A few NOHZ[_FULL] improvements in the [hr]timer code. - Code move from kernel to kernel/time of all time* related code. - New clocksource/event drivers from the ARM universe. I'm really impressed that despite an architected timer in the newer chips SoC manufacturers insist on inventing new and differently broken SoC specific timers. [ Ed. "Impressed"?
