Use a device lifecycle managed action for regulator disable function. This helps prevent mistakes like unregistering out of order in cleanup functions and forgetting to unregister on error paths. Signed-off-by:

Some light sensors can adjust both the HW-gain and integration time. There are cases where adjusting the integration time has similar impact to the scale of the reported values as gain setting has. IIO users do typically expect to handle scale by a single writable 'scale' entry. Driver should then adjust the gain/time accordingly. It however is difficult for a driver to know whether it should change gain or integration time to meet the requested scale. Usually it is preferred to have longer integration time which usually improves accuracy, but there may be use-cases where long measurement times can be an issue. Thus it can be preferable to allow also changing the integration time - but mitigate the scale impact by also changing the gain underneath. Eg, if integration time change doubles the measured values, the driver can reduce the HW-gain to half. The theory of the computations of gain-time-scale is simple. However, some people (undersigned) got that implemented wrong for more than once. Hence some gain-time-scale helpers were introduced. Add some simple tests to verify the most hairy functions.

The vcnl4040/vcnl4200 proximity sensor defaults to 12 bit data resolution, but the chip also supports 16 bit data resolution, which is called proximity high definition (PS_HD). Make the vcnl4040/vcnl4200 proximity sensor use the high definition for all data readings. Please note that in order to preserve the 12 bit integer part of the in_proximity_raw output, the format is changed from integer to fixed point. Signed-off-by:

Make sure we can specify the IRQ trigger type from firmware and drivers won't ignore it. In fact, this how it should be done but since someone might be already depending on the driver to hardcode the trigger type (and not specifying it in firmware), let's do it like this so there's no possible breakage.

Respect the @dev argument in devm_iio_dmaengine_buffer_setup() and bind the IIO DMA buffer lifetime to that device. For the only user of this function, the IIO parent device is the struct device being passed to the API so no real fix in here (just consistency with other IIO APIs). Signed-off-by:

Replace seekdir() with rewinddir() in order to fix a localized glibc bug. One of the glibc patches that stable Gentoo is using causes an improper directory stream positioning bug on 32bit arm. That in turn ends up as a floating point exception in iio_generic_buffer. The attached patch provides a fix by using an equivalent function which should not cause trouble for other distros and is easier to reason about in general as it obviously always goes back to to the start. https://sourceware.org/bugzilla/show_bug.cgi?id=31212Signed-off-by:

The BMI088, BMI085 and BMI090L accelerometer also support I2C protocol, so let's add the missing I2C support. The I2C interface of the {BMI085,BMI088,BMI090L} is compatible with the I2C Specification UM10204 Rev. 03 (19 June 2007), available at http://www.nxp.com. The {BMI085,BMI088,BMI090L} supports I2C standard mode and fast mode, only 7-bit address mode is supported.

In general the complexity of avoiding maybe unused variable warnings is not worth dealing with for the small amount of data saved. In thie case, the i2c driver does include some other code under a CONFIG_ACPI guard but remove the ACPI_PTR() usage anyway to bring keep it inline with the spi driver. Drop include of linux/acpi.h in the spi driver that doesn't need it as struct acpi_device_id is defined in mod_devicetable.h which is already included. Reviewed-by:

This avoids a build warning due to the use of ACPI_PTR(). Given the driver already has APCI specific code under CONFIG_ACPI move the table rather than removing the ACPI_PTR() call as we already have the complexity of CONFIG_ACPI. Dropped a pointless comma after {} terminator whilst moving the code. Cc: Hans de Goede <hdegoede@redhat.com> Reviewed-by:Hans de Goede <hdegoede@redhat.com> Reviewed-by:

In general using ACPI_PTR() leads to more fragile code for a very minor saving in storage in the case of !CONFIG_ACPI so in IIO we prefer not to use it if the only ACPI specific code is the acpi_device_id table. In this case will also suppress a unused variable warning. Reported-by:
