Make it clear that the *_set_trigger_state() hook is responsible for cnvst based conversions by renaming the helper. This may avoid confusions with software trigger support that is going to be introduced. Signed-off-by:

Provide a list of ->available_scan_masks which match the device's capabilities. Basically, these devices are able to scan from 0 to N, N being the highest voltage channel requested by the user. The temperature can be included or not, but cannot be retrieved alone. The consequence is, instead of reading and pushing to the IIO buffers all channels each time, the "minimum" number of channels will be scanned and pushed based on the ->active_scan_mask. For example, if the user wants channels 1, 4 and 5, all channels from 0 to 5 will be scanned and pushed to the IIO buffers. The core will then filter out the unneeded samples based on the ->active_scan_mask that has been selected and only channels 1, 4 and 5 will be available to the user in the shared buffer. Provide a comment in the code explaining this logic. Signed-off-by:

This adds ways for the SoC to wake from accelerometer wake events. In the suspend function we skip disabling the sensor if wakeup-source and events are activated. If buffered reads are enabled they will be deactivated before suspend. As the onboard buffer is only holding up to 32 12-bit X/Y/Z data triplets. Signed-off-by:

The ADC controller has a trimming register for fine-tune the reference voltage. The trimming value comes from the OTP register which will be written during chip production. This patch will read this OTP value and configure it to the ADC register when the ADC controller probes and using dts property "aspeed,trim-data-valid" to determine whether to execute this flow.

In ast2600, ADC integrate dividing circuit at last input channel for battery sensing. This patch use the dts property "battery-sensing" to enable this feature makes the last channel of each adc can tolerance higher voltage than reference voltage. The offset interface of ch7 will be separated when enabling the battery sensing mode. Signed-off-by:

Add the function to set the sampling rate and keep the sampling period for a driver used to wait the fresh value. In addition, since the ADC clock is required when initializing the ADC device, move clk_prepare_enable ahead of the initialization phase. Signed-off-by:

The ADC clock formula is ast2400/2500: ADC clock period = PCLK * 2 * (ADC0C[31:17] + 1) * (ADC0C[9:0] + 1) ast2600: ADC clock period = PCLK * 2 * (ADC0C[15:0] + 1) They all have one fixed divided 2 and the legacy driver didn't handle it. This patch register the fixed factory clock device as the parent of ADC clock scaler to fix this issue. Signed-off-by:

Billy Tsai authored
This patch refactors the model data structure to distinguish the function form different versions of aspeed ADC. - Rename the vref_voltage to vref_fixed_mv and add vref_mv driver data When driver probe will check vref_fixed_mv value and store it to vref_mv which isn't const value. - Add num_channels Make num_channles of iio device can be changed by different model_data - Add need_prescaler flag and scaler_bit_width The need_prescaler flag is used to tell the driver the clock divider needs another Prescaler and the scaler_bit_width to set the clock divider bitfield width.

There is nothing else that needs to be done for this driver. The remove hook calls only the iio_device_unregister() hook. So this driver can use devm_iio_device_register() directly. Signed-off-by:

This change converts the probe of the AD5064 driver to use only device-managed functions. The regulator_bulk_disable() is passed on a devm_add_action_or_reset() hook and the devm_iio_device_register() can be used to register the IIO device. The driver has both I2C and SPI hooks inside, so all these can be removed. Signed-off-by:

This change does a conversion of the driver to use device-managed init functions. The 2 regulators and the clock inits are converted to use devm_add_action_or_reset() callbacks for de-initializing them when the driver unloads. And finally the devm_iio_device_register() function can be use to register the device. The remove hook can finally be removed and the spi_set_drvdata() call can also be removed as the private data is no longer used. Signed-off-by:

For this conversion, the regulators need to have some cleanup hooks registered with devm_add_action_or_reset() and then the devm_io_device_register() call can be used. Signed-off-by:
