This fixes a build issue when CONFIG_IIO_STM32_TIMER_TRIGGER isn't set but used in stm32-dfsdm-adc driver (e.g. CONFIG_STM32_DFSDM_ADC is set): ERROR: "is_stm32_timer_trigger" [drivers/iio/adc/stm32-dfsdm-adc.ko] undefined! There are two possible options to fix this issue: - select IIO_STM32_TIMER_TRIGGER along with CONFIG_STM32_DFSDM_ADC. This is what's being done currently for CONFIG_STM32_ADC. - stub "is_stm32_timer_trigger" function Choice is made to stub this function as suggested in [1]. This is also inspired by similar "is_stm32_lptim_trigger" function (see [2]) in include/linux/iio/timer/stm32-lptim-trigger.h [1] https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1977377.html [2] https://lkml.org/lkml/2017/9/10/124 Fixes: 11646e81 ("iio: adc: stm32-dfsdm: add support for buffer modes") Reported-by:

This patch will ensure compatibility with the new revision of the AD5758 dac converter. The modifications consist of removing the fault_prot_switch function since this option is no longer available, and enabling the ENABLE_PPC_BUFFERS bit in ADC_CONFIG register before setting the PPC current mode. The previous version of the chip was never released to customers so there is no need to support it going forwards. Signed-off-by:

Document support for AD7616 Analog to Digital Converter. Signed-off-by:
Beniamin Bia <beniamin.bia@analog.com> Reviewed-by:

Beniamin Bia authored
The AD7616 is a 12-bit ADC with 16 channels. The AD7616 can be configured to work in hardware mode by controlling it via gpio pins and read data via spi. No support for software mode yet, but it is a work in progress. This device requires a reset in order to update oversampling, so chip info has got a new attribute to mark this. The current assumption that this driver makes for AD7616, is that it's working in Hardware Mode with Serial, Burst and Sequencer modes activated. To activate them, following pins must be pulled high: -SER/PAR -SEQEN And following must be pulled low: -WR/BURST -DB4/SEQEN Datasheets: Link: https://www.analog.com/media/en/technical-documentation/data-sheets/ad7616.pdf Signed-off-by:

Available oversampling ratios and scales can be shown by calling a common ad7606_show_avail function which takes as parameters the array which stores the values, together with the size of the array. Oversampling options are now defined in chip info structure and they are loaded at probe. Has_Oversampling attribute was removed because oversampling_num was added and it is not needed anymore. The purpose of this patch is to deal with the scale_avail and oversampling_avail arrays in a generic way. This makes it easier to add support for new devices which will work with different scales and oversampling ratios. It is also an intermediate step for adding support for ad7616 which has different oversampling sampling ratios available. Signed-off-by:
