| * hwmon: (gpio-fan) Remove un-necessary speed_index lookup for thermal hookNishanth Menon2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 000e0949148382c4962489593a2f05504c2a6771 upstream. Thermal hook gpio_fan_get_cur_state is only interested in knowing the current speed index that was setup in the system, this is already available as part of fan_data->speed_index which is always set by set_fan_speed. Using get_fan_speed_index is useful when we have no idea about the fan speed configuration (for example during fan_ctrl_init). When thermal framework invokes gpio_fan_get_cur_state=>get_fan_speed_index via gpio_fan_get_cur_state especially in a polled configuration for thermal governor, we basically hog the i2c interface to the extent that other functions fail to get any traffic out :(. Instead, just provide the last state set in the driver - since the gpio fan driver is responsible for the fan state immaterial of override, the fan_data->speed_index should accurately reflect the state.

| * hwmon: (dell-smm) Blacklist Dell Studio XPS 8000Thorsten Leemhuis2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 6220f4ebd7b4db499238c2dc91268a9c473fd01c upstream. Since Linux 4.0 the CPU fan speed is going up and down on Dell Studio XPS 8000 and 8100 for unknown reasons. The 8100 was already blacklisted in commit a4b45b25f18d ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100"). This patch blacklists the XPS 8000. Without further debugging on the affected machine, it is not possible to find the problem.

* | hwmon: qpnp-adc-voltage: Add optional VADC propertySiddartha Mohanadoss2016-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | Add option to select whether a fresh calibration needs to be performed when performing the channel measurement. If the property is not present the default value of using calibration measurement collected from a timer will be used. For most cases using a measurement collected from a timer interval should suffice and the default value can be used.

* | thermal: qpnp-adc-tm: Support refreshed BTM driverSiddartha Mohanadoss2016-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BTM (Battery temperature module) peripheral driver on the PMIC (Power management IC) supports threshold monitoring and notifies clients when thresholds are crossed. PMCOBALT supports refreshed BTM peripheral register interface and the driver uses compatible property qpnp-adc-tm-hc to distinguish using the refreshed peripheral. The external client interface with the driver remains the same. Updates include handling the interrupt when the thresholds are crossed,programming the threholds and configuring the hardware based on the refreshed design. BTM peripheral needs the VADC_HC peripheral to compute the gain/offset that are used to reverse compute the threhold values to ADC code. Some of the reverse computation API's such as calculating thermistor thresholds require the gain and offset values before computing the ADC code to be programmed. This requires modification to the existing calibration API in the VADC_HC driver to calculate the reference calibration points and store these values for clients to use in the reverse computation Change-Id: I989cfa4f40e7f1671f04dfa9d4c3fe2ccbbc44ab Signed-off-by: Siddartha Mohanadoss <smohanad@codeaurora.org>

* hwmon: (tmp102) Force wait for conversion time for the first valid dataNishanth Menon2015-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TMP102 works based on conversions done periodically. However, as per the TMP102 data sheet[1] the first conversion is triggered immediately after we program the configuration register. The temperature data registers do not reflect proper data until the first conversion is complete (in our case HZ/4). The driver currently sets the last_update to be jiffies - HZ, just after the configuration is complete. When TMP102 driver registers with the thermal framework, it immediately tries to read the sensor temperature data. This takes place even before the conversion on the TMP102 is complete and results in an invalid temperature read. Depending on the value read, this may cause thermal framework to assume that a critical temperature event has occurred and attempts to shutdown the system. Instead of causing an invalid mid-conversion value to be read erroneously, we mark the last_update to be in-line with the current jiffies. This allows the tmp102_update_device function to skip update until the required conversion time is complete. Further, we ensure to return -EAGAIN result instead of returning spurious temperature (such as 0C) values to the caller to prevent any wrong decisions made with such values. NOTE: this allows the read functions not to be blocking and allows the callers to make the decision if they would like to block or try again later. At least the current user(thermal) seems to handle this by retrying later. A simpler alternative approach could be to sleep in the probe for the duration required, but that will result in latency that is undesirable and delay boot sequence un-necessarily.

* hwmon: (scpi) skip unsupported sensors properlySudeep Holla2015-11-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it's assumed that firmware exports only the class of sensors supported by the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NCT6792 and NCT6793 are mostly register compatible to NCT6791, but temperature sources are different and difficult to manage with a single temperature label array.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The description in the driver states: "ABX500 does not provide auto ADC, so to monitor the required temperatures, a periodic work is used. It is more important to not wake up the CPU... If the chip gets too hot during a sleep state it's most likely due to external factors, such as the surrounding temperature and nothing can be done in S/W." So it makes no sense to keep IRQs enabled as it need not be wakeup source.
