iio: imu: inv_icm42600: Fix I2C init possible nack

2022-04-16T14:03:58Z

This register write to REG_INTF_CONFIG6 enables a spike filter that is impacting the line and can prevent the I2C ACK to be seen by the controller. So we don't test the return value.

iio:proximity:sx9324: Fix hardware gain read/write

2022-04-04T08:19:02Z

There are four possible gain values according to 'sx9324_gain_vals[]': 1, 2, 4, and 8 The values are off by one when writing and reading the register. The bits should be set according to this equation: ilog2() + 1 so that a gain of 8 is 0x4 in the register field and a gain of 4 is 0x3 in the register field, etc. Note that a gain of 0 is reserved per the datasheet. The default gain (SX9324_REG_PROX_CTRL0_GAIN_1) is also wrong. It should be 0x1 << 3, i.e. 0x8, not 0x80 which is setting the reserved bit 7. Fix this all up to properly handle the hardware gain and return errors for invalid settings.

iio:proximity:sx_common: Fix device property parsing on DT systems

2022-04-04T08:19:01Z

After commit 7a3605bef878 ("iio: sx9310: Support ACPI property") we started using the 'indio_dev->dev' to extract device properties for various register settings in sx9310_get_default_reg(). This broke DT based systems because dev_fwnode() used in the device_property*() APIs can't find an 'of_node'. That's because the 'indio_dev->dev.of_node' pointer isn't set until iio_device_register() is called. Set the pointer earlier, next to where the ACPI companion is set, so that the device property APIs work on DT systems.
