The ST IIS328DQ is an accelerometer sensor, which is compatible with the already supported ST H3LIS331DL. So add the new compatible with a fallback to the ST sensor binding. Link: https://lore.kernel.org/linux-iio/2bac9ecf-9d2e-967e-9020-1c950487d781@i2se.com/Suggested-by:

The <linux/bitops.h> header is included in the stx104 driver so that we can use the BIT() macro. This macro is actually defined in the <linux/bits.h> header, so replace the <linux/bitops.h> header inclusion with <linux/bits.h>. Signed-off-by:

The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. Includes trivial header inclusion tidy up. Suggested-by:

The left side of the loop condition never becomes false. hwchan cannot be NULL, because it points to elements of the hw_channels array that takes one of 4 predefined values: pm8018_xoadc_channels, pm8038_xoadc_channels, pm8058_xoadc_channels, pm8921_xoadc_channels.

Currently, the driver handles CH_FUNC_CURRENT_INPUT_LOOP_POWER and CH_FUNC_CURRENT_INPUT_EXT_POWER completely identically. But that's not correct. In order for CH_FUNC_CURRENT_INPUT_LOOP_POWER to work, two changes must be made: (1) expose access to the DAC_CODE_x register so that the intended output current can be set, i.e. expose the channel as both current output and current input, and (2) per the data sheet When selecting the current input loop powered function, tie the VIOUTN_x pin to ground via the on-chip 200 kΩ resistor by enabling the CH_200K_TO_GND bit in the ADC_CONFIGx registers.

Depending on the actual hardware wired up to a digital input channel, it may be necessary to configure the ad74413r to sink a small current. For example, in the case of a simple mechanical switch, the charge on the external 68 nF capacitor (cf. the data sheet's Figure 34) will keep the channel as reading high even after the switch is turned off again.

Don't error if the device-id found don't match the device-id for the TMP117 sensor since other TMPxxx might be compatible to the TMP117. The fallback mechanism tries to gather the required information from the of_device_id or from the i2c_client information. The commit also prepares the driver for adding new devices more easily by making use of switch-case at the relevant parts. Signed-off-by:

During digital filters settling time the driver is expected to drop samples since they can be corrupted. Introduce the capability to drop a given number of samples according to the configured ODR. Add sample_to_discard for LSM6DSM-like sensors since new generation devices (e.g. LSM6DSO) support DRDY mask where corrupted samples are masked in hw with values greather than 0x7ffd so the driver can easily discard them. I have not added sample_to_discard support for LSM6DS3 or LSM6DS3H since I do not have any sample for testing at the moment. Reported-by:

meson_sar_adc_lock() might return an error if BL30 doesn't release its lock on the hardware. Just returning early from .remove() is wrong however as this keeps the clocks and regulators on which is never cleaned up later. Given the BL30 not giving up its lock is a strong hint for broken behaviour, and there is nothing we can do about that: Just clean up ignoring the fact that we're not holding the lock. Signed-off-by:

Older firmwares still send sensor configuration using a list of registers with opaque values defined during sensor tuning. sx9234 and sx9360 sensor on ACPI based devices are concerned.

This driver is so far from making correct use of the IIO infrastructure and ABI that if someone wanted to make the driver suitable for moving out of staging, they would more or less be starting from scratch. As such there is little point in keeping the existing code in staging. Note this was only user of the meter.h header so that is dropped. There are no other drivers in the staging/iio/meter directory so drop the build system files as well. Signed-off-by:
