Add support for AD4111/AD4112/AD4114/AD4115/AD4116. The AD411X family encompasses a series of low power, low noise, 24-bit, sigma-delta analog-to-digital converters that offer a versatile range of specifications. This family of ADCs integrates an analog front end suitable for processing both fully differential and single-ended, bipolar voltage inputs addressing a wide array of industrial and instrumentation requirements. - All ADCs have inputs with a precision voltage divider with a division ratio of 10. - AD4116 has 5 low level inputs without a voltage divider. - AD4111 and AD4112 support current inputs (0 mA to 20 mA) using a 50ohm shunt resistor.

The ADCs supported by this driver feature a sequencer that read in a loop all the enabled chanels. When setting the individual sampling frequency for each channel and enabling multiple channels, the effective of each channel will be lower than the actual set value. Document this behaviour in a comment. Reviewed-by:

Drop setting .has_temp and .has_input_buf to false in device info struct. Drop array of device info structs and use individual structs for all; drop models enum as no longer needed. This improves readability as the structs are pointed directly. Reviewed-by:

Sigma delta ADCs with a sequencer need to disable the previously enabled channel when reading using ad_sigma_delta_single_conversion(). This was done manually in drivers for devices with sequencers. This patch implements handling of single channel disabling after a single conversion. Reviewed-by:

Add support for: AD4111, AD4112, AD4114, AD4115, AD4116. AD411x family ADCs support a VCOM pin. The purpose of this pin is to offer a dedicated common-mode voltage input for single-ended channels. This pin is specified as supporting a differential channel with VIN10 on model AD4116. AD4111/AD4112 support current channels. Support is implemented using single-channel and "adi,current-channel".

There are ADCs that are differential but support to measure single-ended signals on the same channels by connecting a constant voltage to the negative input pin. This property allows to properly define a single-ended channel that requires two inputs to be specified. Software can use the presence of this property to mark the channel as not differential.

The current error handling for calls such as devm_clk_get_enabled() in the adi-axi-adc probe() function means that, if a property such as 'clocks' (for example) is not present in the devicetree when booting a kernel with the driver enabled, the resulting error message will be vague, e.g.: |adi_axi_adc 44a00000.backend: probe with driver adi_axi_adc failed with error -2 Change the devm_clk_get_enabled(), devm_regmap_init_mmio(), and devm_iio_backend_register() checks to use dev_err_probe() with some context for easier debugging. After the change: |adi_axi_adc 44a00000.backend: error -ENOENT: failed to get clock |adi_axi_adc 44a00000.backend: probe with driver adi_axi_adc failed with error -2 Signed-off-by:

Merge tag 'parisc-for-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull parisc fix from Helge Deller: "On parisc we have suffered since years from random segfaults which seem to have been triggered due to cache inconsistencies. Those segfaults happened more often on machines with PA8800 and PA8900 CPUs, which have much bigger caches than the earlier machines. Dave Anglin has worked over the last few weeks to fix this bug. His patch has been successfully tested by various people on various machines and with various kernels (6.6, 6.8 and 6.9), and the debian buildd servers haven't shown a single random segfault with this patch. Since the cache handling has been reworked, the patch is slightly bigger than I would like in this stage, but the greatly improved stability IMHO justifies the inclusion now" * tag 'parisc-for-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Try to fix random segmentation faults in package builds
