isl29028_chip_init_and_power_on() calls isl29028_set_als_scale() and this is not needed until the user actually needs to take a reading from the ALS/IR sensor. This patch moves the isl29028_set_als_scale() call from isl29028_chip_init_and_power_on() to isl29028_set_als_ir_mode(). This sets the stage for faster resume times from runtime power management if the user is only querying the proximity sensor. Signed-off-by:

isl29028_chip_init_and_power_on() calls isl29028_set_proxim_sampling() and this is not needed until the user actually needs to take a proximity reading. This patch moves the isl29028_set_proxim_sampling() call from isl29028_chip_init_and_power_on() to isl29028_enable_proximity(). This sets the stage for faster resume times from the runtime power management if the user is only querying the ALS/IR sensor. Signed-off-by:

isl29028_enable_proximity() has a boolean argument named enable. This function is only called once and the enable flag is set to true in that call. This patch removes the enable parameter from that function. Signed-off-by:

isl29028_write_raw() contains unnecessary parenthesis when checking to see if the passed in lux scale is valid. This patch removes the unnecessary parenthesis. Signed-off-by:

If the call to devm_iio_device_alloc() fails, then isl29028_probe() logs a message saying that memory cannot be allocated. The user's system most likely has larger issues at this point. This patch removes that error message since the error code is passed on and the message is not necessary. Signed-off-by:

If the call to isl29028_chip_init_and_power_on() in isl29028_probe() fails, then isl29028_probe() will log an error message. All of the error paths in that call path already have error logging in place. This patch removes the unnecessary logging. Signed-off-by:

When isl29028_set_als_scale() fails, it was up to both callers to log the failure message. This patch moves the logging into isl29028_set_als_scale() to reduce the overall amount of code in the driver. Signed-off-by:

isl29028_proxim_get() checks to see if the promixity needs to be enabled on the chip and then calls isl29028_read_proxim(). There are no other callers of isl29028_read_proxim(). The naming between these two functions can be confusing so this patch combines the two to avoid the confusion. Signed-off-by:

Two separate calls to regmap_update_bits() in isl29028_set_als_scale() and isl29028_set_als_ir_mode() did not have their function arguments on the next line aligned correctly to the open parenthesis. This patch corrects the alignment. Signed-off-by:

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it. Signed-off-by:

ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. Fix up the 35ms delays here to use msleep() and reduce the load on the hrtimer subsystem.

This adds TI's tlc4541 16-bit ADC driver. Which is a single channel ADC. Supports raw and trigger buffer access. Also supports the tlc3541 14-bit device, which has not been tested. Implementation of the tlc3541 is fairly straight forward thou. Acked-by:

Driver was checking for direct mode before changing oversampling ratios, but was not locking it. Use the claim/release helper functions to guarantee the device stays in direct mode while the oversampling ratios are being updated. Continue to use the drivers private state lock to protect against conflicting direct mode access of the state data. Signed-off-by:

This changes the reference voltage regulator matching string from "refin" to "vref". This is to be consistent with other A/DC chips that also use "vref-supply" in their device tree bindings. Signed-off-by:

This drops the "ti-" prefix from the module name. It makes the module name consistent with other iio ti-ads* drivers and it makes the driver work with device tree (the spi subsystem drops the "ti," prefix when matching compatible strings from device tree). Tested working on LEGO MINDSTORMS EV3 with the following device tree node: adc@3 { compatible = "ti,ads7957"; reg = <3>; #io-channel-cells = <1>; spi-max-frequency = <10000000>; vref-supply = <&adc_ref>; }; Signed-off-by: -

When a consumer calls iio_read_channel_processed() the IIO core tries to apply scaling to the value, but if the channel only supports reading raw values, we should return that raw value to the cosumer instead of an error. This is what userspace is expected to do with sensors only providing raw values so the kernel should do the same, so as to avoid adding scaling boilerplate to drivers for hardware that actually return processed values from raw reads. A sensor not providing a scale, but providing a _raw attribute could be valid if for example the scale is the default of 1, but an offset needs to be applied to convert to the _processed form.

This is the IIO driver for AVIA HX711 ADC which is mostly used in weighting cells. The protocol is quite simple and using GPIOs: One GPIO is used as clock (SCK) while another GPIO is read (DOUT) The raw value read from the chip is delivered. To get a weight one needs to subtract the zero offset and scale it. Signed-off-by:
