* hwmon: (acpi_power_meter) Fix acpi_bus_get_device() return value checkYijing Wang2013-11-20
| | | | | | | | | Since acpi_bus_get_device() returns plain int and not acpi_status, ACPI_FAILURE() should not be used for checking its return value. Fix that. Signed-off-by: Yijing Wang <wangyijing@huawei.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (nct6775) NCT6791 supports weight control only for CPUFANGuenter Roeck2013-11-18
| | | | | | | | Unlike other chips supported by this driver, the NCT6791 only has a single set of registers to configure weighted fan control. Enable it only for the single channel supporting it. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (nct6775) Monitor additional temperature registersGuenter Roeck2013-11-18
| | | | | | | | | | | The number of SMIOVT registers on NCT6779 and NCT6791 is limited to 2. As result, the driver may not report some of the temperatures used for fan control. This can result in some of the pwmX_temp_sel or pwm2_weight_temp_sel attributes to wrongly return 0. Fortunately, the chip has registers to monitor those temperatures. Add them to the list of temperatures to report. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

| | | | | | | | | | | | | | | | | | | | | | | | Add bit defines for the status register. And add a function lm90_is_tripped() which will read status register and return tripped or not, then lm90_alert can call it directly, and in the future the IRQ thread also can use it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bit 2 of status register 2 on MAX6696 (external diode 2 open) sets ALERT; the bit thus has to be listed in alert_alarms. Also display a message in the alert handler if the condition is encountered. Even though not all overtemperature conditions cause ALERT to be set, we should not ignore them in the alert handler. Display messages for all out-of-range conditions.
