Internal clock of AD719X devices can be made available on MCLK2 pin. Add clock provider to support this functionality when clock cells property is present. The clock source can be either provided externally or the internal clock is used. Pair of clocks and clock-names property is mutally exclusive with #clock-cells property. Modify second example to showcase the mode where internal clock is used. Signed-off-by:

There are actually 4 configuration modes of clock source for AD719X devices. Either a crystal can be attached externally between MCLK1 and MCLK2 pins, or an external CMOS-compatible clock can drive the MCLK2 pin. The other 2 modes make use of the 4.92MHz internal clock. Undocumented properties adi,int-clock-output-enable and adi,clock-xtal still supported for backward compatibility, but their use is highly discouraged. Use cleaner alternative of configuring external clock by using clock names mclk and xtal. Functionality of AD7192_CLK_INT_CO will be implemented in complementary patch by adding clock provider.

Either a crystal can be attached externally between MCLK1 and MCLK2 pins, or an external CMOS-compatible clock can drive the MCLK2 pin. The other 2 modes make use of the 4.92MHz internal clock. To configure external clock as either a crystal or a CMOS-compatible clock, changing the register settings is necessary. Therefore, add clock name xtal alongside mclk. By selecting one or the other, the register is configured. The presence of an external clock source is optional, not required. When both clocks and clock-names properties are present, an external clock source is used. If the intention is to use the internal clock, both properties should be absent. Modify required properties accordingly. Signed-off-by:

Marek Vasut authored
Move scale values into a static table, perform look up of those scale values in noa1305_scale() simply by using the integration time register content as an index, because the integration time register content directly maps to the table values. Signed-off-by:

Make noa1305_measure() behave similar to noa1305_scale(), make it assign the 'val' output variable on success and return IIO_VAL_INT. This further simplifies noa1305_read_raw() and allows removal of ret variable altogether. Signed-off-by:

Marek Vasut authored
The only channel this hardware supports is IIO_LIGHT, if the channel is anything else, exit right away. The 'ret' variable is now always only assigned by noa1305_measure(), do not initialize it anymore. Update function parameter indent. No functional change. Signed-off-by:

This makes use of the new devm_regulator_get_enable_read_voltage() helper function to reduce boilerplate code in the MCP3911 ADC driver. The error message is slightly changed since there are fewer error return paths. An extra parameter is added to the config callback to avoid adding state that is not used outside of the probe() function. Signed-off-by:

By using devm_iio_device_register(), we can drop the remove() callback in the mcp4922 driver. We can also remove spi_set_drvdata() since there are no more callers of spi_get_drvdata(). Also use dev_err_probe() while we are at it. Signed-off-by:

According to the datasheet, both pressure and temperature can go up to oversampling x32. With this option, the maximum measurement time is not 80ms (this is for press x32 and temp x2), but it is 130ms nominal (calculated from table 3.9.2) and since most of the maximum values are around +15%, it is configured to 150ms.

This is a new driver for Analog Devices Inc. AD4695 and similar ADCs. The initial driver supports initializing the chip including configuring all possible LDO and reference voltage sources as well as any possible voltage input channel wiring configuration. Only the 4-wire SPI wiring mode where the CNV pin is tied to the CS pin is supported at this time. And reading sample data from the ADC can only be done in direct mode for now. Co-developed-by:
