move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

iio: humidity: Add support for ENS210

2024-08-17T14:37:37Z

Add support for ENS210/ENS210A/ENS211/ENS212/ENS213A/ENS215. The ENS21x is a family of temperature and relative humidity sensors with accuracies tailored to the needs of specific applications.

iio: humidity: am2315: make use of iio_for_each_active_channel()

2024-08-03T09:13:40Z

Use iio_for_each_active_channel() to iterate over active channels accessing '.masklength' so it can be annotated as __private when there are no more direct users of it.

iio: humidity: si7020: add heater support

2024-06-13T18:19:23Z

This patch adds support for the integrated on-chip heater that is present on all the devices supported by this driver (si7020, si7021, si7013, th6). In order to configure the heater, the driver interacts with the following device registers: * User Register - the 2nd bit of this register is a "Heater Enable bit" (0 means that the heater is off, 1 means that it's on). * Heater Register - this register is present only on the si70xx devices and controls the current flowing through the heater. The 4 lower bits of this register can be assigned values from 0x0 to 0xF.

iio: humidity: hdc3020: fix hysteresis representation

2024-06-09T10:05:03Z

According to the ABI docs hysteresis values are represented as offsets to threshold values. Current implementation represents hysteresis values as absolute values which is wrong. Nevertheless the device stores them as absolute values and the datasheet refers to them as clear thresholds. Fix the reading and writing of hysteresis values by including thresholds into calculations. Hysteresis values that result in threshold clear values that are out of limits will be truncated. To check that the threshold clear values are correct, registers are read out using i2ctransfer and the corresponding temperature and relative humidity thresholds are calculated using the formulas in the datasheet.

iio: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-27T08:48:57Z

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

iio: humidity: hdc3020: add reset management

2024-03-25T20:10:13Z

The HDC3020 provides an active low reset signal that must be handled if connected. Asserting this signal turns the device into Trigger-on Demand measurement mode, reducing its power consumption when no measurements are required like in low-power modes. According to the datasheet, the longest "Reset Ready" is 3 ms, which is only taken into account if the reset signal is defined.

iio: humidity: hdc3020: add power management

2024-03-25T20:10:13Z

The HDC3020 sensor carries out periodic measurements during normal operation, but as long as the power supply is enabled, it will carry on in low-power modes. In order to avoid that and reduce power consumption, the device can be switched to Trigger-on Demand mode, and if possible, turn off its regulator. According to the datasheet, the maximum "Power Up Ready" is 5 ms. Add resume/suspend pm operations to manage measurement mode and regulator state.

iio: humidity: hts211: drop casting to void in dev_set_drvdata

The C standard specifies that there is no need to cast from a pointer to void [1]. Therefore, it can be safely dropped.
