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:

Some platforms have separated the end-of-conversion information from the usual ISR/IMR/IER/IDR registers, into EOC_ISR/EOC_IMR/EOC_IER/EOC_IDR. To cope with both variants, helpers are being added, that will make code more clear and more easy to read. Signed-off-by:

Convert the driver to platform specific structures. This means: - create a register layout struct that will hold offsets for registers - create a platform struct that will hold platform information (number of channels, indexes for different channels and pointer to layout struct) - convert specific macros that are platform dependent into platform variables This step is in fact a no-op, but allows the driver to be more flexible and for future enhancement including adding new platforms that are partly compatible with the current driver and differ slightly in register layout or capabilities for example.
