iio:humidity:hts221: rearrange iio trigger get and register

2022-06-19T16:22:49Z

IIO trigger interface function iio_trigger_get() should be called after iio_trigger_register() (or its devm analogue) strictly, because of iio_trigger_get() acquires module refcnt based on the trigger->owner pointer, which is initialized inside iio_trigger_register() to THIS_MODULE. If this call order is wrong, the next iio_trigger_put() (from sysfs callback or "delete module" path) will dereference "default" module refcnt, which is incorrect behaviour.

iio:common:meas-spec: Move exports into IIO_MEAS_SPEC_SENSORS

2022-02-18T11:42:26Z

The obvious choice of ms_sensors felt rather too likely to clash with other namespaces introduced in future, hence the longer abbreviation. In order to avoid unnecessary pollution of the global symbol namespace move the common/library functions into a specific namespace and import that into the various specific device drivers that use them.

iio: humidity: hdc100x: Add ACPI HID table

2022-01-30T13:44:53Z

x86 boards may use ACPI HID "TXNW1010" for the hdc100x device. TI told us "The ACPI ID for TI is: https://uefi.org/node/1028 (TXNW), therefore it would most likely be appropriate to use TXNW1010." So add an ACPI match table for that accordingly.

iio: humidity: hdc100x: Add margin to the conversion time

2021-07-24T17:13:02Z

The datasheets have the following note for the conversion time specification: "This parameter is specified by design and/or characterization and it is not tested in production." Parts have been seen that require more time to do 14-bit conversions for the relative humidity channel. The result is ENXIO due to the address phase of a transfer not getting an ACK. Delay an additional 1 ms per conversion to allow for additional margin.

iio: hid-sensors: Update header includes

2021-06-16T13:53:13Z

General driver churn doesn't always include updates of header includes. Manual review of the output of the include-what-you-use checker lead to the following cleanup. Hopefuly this brings things back to a good state for the hid-sensor drivers.

A namespace for exported symbols makes clear who is a provider and who is a consumer of the certain resources. Besides that, it doesn't pollute the common namespace.

iio: am2315: Remove acpi_device_id table

With CONFIG_ACPI=n and -Werror, 0-day reports: drivers/iio/humidity/am2315.c:259:36: error: 'am2315_acpi_id' defined but not used According to Andy Shevchenko, the ACPI ID used in this driver is fake and does not really exist. Remove it and with it ACPI support from the driver. Note that, if an explicit of_device_id table is added to the driver it could support the PRP0001 based ACPI approach.
