By bailing out early if chan->output is false for the IIO_CHAN_INFO_RAW, indentation can be decreased by a tab and code readability improved. Suggested-by:

The DAC register is 16 bits wide, so the value passed by write_raw() should be checked against that limit. Rather than hardcoding the 16-bit maximum value limit, use a define to improve readability and make the intention of the code clearer. The explicit cast is also avoided by instead explicitly checking for negative values. Suggested-by:

The ADC conversion procedure requires several device I/O operations performed in a particular sequence. If stx104_read_raw() is called concurrently, the ADC conversion procedure could be clobbered. Prevent such a race condition by utilizing a mutex. Fixes: 4075a283 ("iio: stx104: Add IIO support for the ADC channels") Signed-off-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:
