2023-04-08iio: light: tsl2772: fix reading proximity-diodes from device treeBrian Masney
tsl2772_read_prox_diodes() will correctly parse the properties from device tree to determine which proximity diode(s) to read from, however it didn't actually set this value on the struct tsl2772_settings. Let's go ahead and fix that.

2023-03-12iio: adc: max11410: fix read_poll_timeout() usageNuno Sá
Even though we are passing 'ret' as stop condition for read_poll_timeout(), that return code is still being ignored. The reason is that the poll will stop if the passed condition is true which will happen if the passed op() returns error. However, read_poll_timeout() returns 0 if the *complete* condition evaluates to true. Therefore, the error code returned by op() will be ignored. To fix this we need to check for both error codes: * The one returned by read_poll_timeout() which is either 0 or ETIMEDOUT. * The one returned by the passed op().

The CIO-DAC series of devices only supports DAC values up to 12-bit rather than 16-bit. Trying to write a 16-bit value results in only the lower 12 bits affecting the DAC output which is not what the user expects. Instead, adjust the DAC write value check to reject values larger than 12-bit so that they fail explicitly as invalid for the user.

2023-02-18iio: buffer: make sure O_NONBLOCK is respectedNuno Sá
For output buffers, there's no guarantee that the buffer won't be full in the first iteration of the loop in which case we would block independently of userspace passing O_NONBLOCK or not. Fix it by always checking the flag before going to sleep. While at it (and as it's a bit related), refactored the loop so that the stop condition is 'written != n', i.e, run the loop until all data has been copied into the IIO buffers. This makes the code a bit simpler.

With commit e21b5b1f2669 ("iio: light: vcnl4000: Preserve conf bits when toggle power") the vcnl4040 sensor started to depend on the lock, but it was missed to initialize it in vcnl4040's init function.

+/-1200uT is a MAGN sensor full measurement range. Magnetometer scale is the magnetic sensitivity parameter. It is referenced as 0.1uT according to datasheet and magnetometer channel unit is Gauss in sysfs-bus-iio documentation. Gauss and uTesla unit conversion relationship as follows: 0.1uT = 0.001Gs. Set magnetometer scale and available magnetometer scale as fixed 0.001Gs.

2023-01-21iio: light: vcnl4000: Make irq handling more genericMårten Lindahl
This driver supports 4 chips, by which only one (vcnl4010) handles interrupts and has support for triggered buffer. The setup of these functions is hardcoded for vcnl4010 inside the generic vcnl4000_probe, and thus ignores the chip specific configuration structure where all other chip specific functions are specified. This complicates adding interrupt handler and triggered buffer support to chips which may have support for it. Add members for irq threads and iio_buffer_setup_ops to the generic vcnl4000_chip_spec struct, so that instead of checking a chip specific boolean irq support, we check for a chip specific triggered buffer handler, and/or a chip specific irq thread handler.

2023-01-21iio: light: cm32181: Fix PM support on system with 2 I2C resourcesKai-Heng Feng
Commit c1e62062ff54 ("iio: light: cm32181: Handle CM3218 ACPI devices with 2 I2C resources") creates a second client for the actual I2C address, but the "struct device" passed to PM ops is the first I2C client that can't talk to the sensor. That means the I2C transfers in both suspend and resume routines can fail and blocking the whole suspend process. Instead of using the first client for I2C transfer, use the I2C client stored in the cm32181 private struct so the PM ops can get the correct I2C client to really talk to the sensor device.
