ecause clk_disable_unprepare() already checked NULL clock parameter, so the additional check is unnecessary, just remove it. Signed-off-by:

Currently, only the 112bit PROM with 7 words is supported. However the ms58xx family also have devices with a 128bit PROM on 8 words. See AN520: C-CODE EXAMPLE FOR MS56XX, MS57XX (EXCEPT ANALOG SENSOR), AND MS58XX SERIES PRESSURE SENSORS and the various device datasheets. The difference is that the CRC is the 4 LSBs of word7 instead of being the 4 MSBs of word0. Signed-off-by:

The CRC calculation always happens on 8 words which is why there is an extra element in the prom array of struct ms_tp_dev. However, on ms5637 and similar, only 7 words are readable. Then, set MS_SENSORS_TP_PROM_WORDS_NB to 8 and stop passing a len parameter to ms_sensors_tp_crc_valid as this simply hide the fact that it is hardcoded. Finally, use the newly introduced hw->prom_len to know how many words can be read. Signed-off-by:

Some sensors in the ms58xx family have a different PROM length and a different number of available resolution. introduce struct ms_tp_hw_data to handle those differences. Signed-off-by:

Some enums might have gaps or reserved values in the middle of their value range. E.g. consider a 2-bit enum where the values 0, 1 and 3 have a meaning, but 2 is a reserved value and can not be used. Add support for such enums to the IIO enum helper functions. A reserved values is marked by setting its entry in the items array to NULL rather than the normal descriptive string value.

Add channel description for hinge sensor, including channel label attribute and raw data description. Signed-off-by:

Ye Xiang authored
The Hinge sensor is a common custom sensor on laptops. It calculates the angle between the lid (screen) and the base (keyboard). In addition, it also exposes screen and the keyboard angles with respect to the ground. Applications can easily get laptop's status in space through this sensor, in order to display appropriate user interface. Signed-off-by:

Currently custom sensors properties are not decoded and it is up to user space to interpret. Some manufacturers already standardized the meaning of some custom sensors. They can be presented as a proper IIO sensor. We can identify these sensors based on manufacturer and serial number property in the report. This change is identifying hinge sensor when the manufacturer is "INTEL". This creates a platform device so that a sensor driver can be loaded to process these sensors. Signed-off-by:

qcom_vadc7_scale_hw_calib_die_temp() uses a table format different from the rest of volt/temp conversion functions in this file. Also the conversion functions results in non-monothonic values conversion, which seems wrong. Rewrite qcom_vadc7_scale_hw_calib_die_temp() to use qcom_vadc_map_voltage_temp() directly, like the rest of conversion functions do. Signed-off-by:
