2013-02-06hwmon: (pmbus/zl6100) Add support for VMON/VDRVGuenter Roeck
Some of the ZL6100 compatible chips support monitoring a separate voltage pin, VMON (ZL2004) or VDRV (ZL91xx). Report it as in2 / vmon. The chips support implicit warning limits for VMON/VDRV, as percentage of the respective critical voltage. Support by reading/writing the critical voltages and calculating the associated warning voltages. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-02-06hwmon: (pmbus) Add function to clear sensor cacheGuenter Roeck
For PMBus chips, modifying one limit register may affect other limits. Since limits are all cached in the PMBus core driver, related changes are not reflected in reported limits. Introduce function to clear the attribute cache. After calling this function, the core pmbus driver re-reads all cached values. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-02-06hwmon: (pmbus) Add support for additional voltage sensorGuenter Roeck
Some PMBus chips support monitoring an additional non-standard voltage. While this voltage can in many cases be supported by simulating an additional sensor page, this does not work in all cases. Specifically, it is problematic if the data format is linear and the voltage is reported in LINEAR11 format. Since output voltages use LINEAR16, and the exponent for LINEAR16 data is chip-wide and fixed, this can result in overflows. To solve this problem, add support for an additional virtual input voltage, call it 'vmon', and treat this voltage as input voltage (which, when the chip supports linear data format, uses LINEAR11).

2013-02-06hwmon: (pmbus) Use krealloc to allocate attribute memoryGuenter Roeck
So far, attribute memory was allocated by pre-calculating the maximum possible amount of attributes. Not only does this waste memory, it is also risky because the calculation might be wrong. It also requires a lot of defines to specify the maximum number of attributes per class. Allocate attribute memory using krealloc() instead. That means we have to use kfree(), since devm_krealloc() does not exist, but that is still less costly and less risky than trying to predict the number of attributes at the beginning. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-02-06hwmon: (pmbus) Simplify memory allocation for sensor attributesGuenter Roeck
Since memory is now allocated with dev_ functions, we no longer need to keep track of allocated memory. Sensor memory allocation can therefore be simplified significantly. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-02-06hwmon: (pmbus) Improve boolean handlingGuenter Roeck
Boolean handling depends on storing the sensor data index in sensor_device_attr as part of the index variable. This limits the number of sensor attributes to 256, and means the sensor sequence number actually has to be maintained to be able to access sensor data from boolean functions. Rework the code to store sensor pointers in the pmbus_boolean data structure directly. With this approach, the number of supportable sensors is now unlimited.

2013-02-06hwmon: (pmbus) Simplify memory allocation for labels and booleansGuenter Roeck
Since memory is now allocated with dev_ functions, we no longer need to keep track of allocated memory. Memory allocation for booleans and labels can therefore be simplified substantially by allocating it only as needed. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2013-02-06hwmon: (sht15) check GPIO directionsVivien Didelot
Without this patch, the SHT15 driver may fail silently with a non-bidirectional data line and/or an input-only clock line. This patch checks the return value of gpio_direction_* function calls and returns the error code (if any) to the caller. If an error occurs in the read work function (work_funct_t), we wake the queue up directly without updating the data->state flag, to notice the waiter of the I/O error. The patch also makes minor cleanups: s/error_ret/unlock for some labels and uses devm_gpio_request_one() for the clock line.
