iio: adc: add ADC driver for the TI TSC2046 controller

2021-05-17T12:49:11+00:00

Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for the touchscreen use case. By implementing it as an IIO ADC device, we can make use of resistive-adc-touch and iio-hwmon drivers. Polled readings are currently not implemented to keep this patch small, so iio-hwmon will not work out of the box for now. So far, this driver was tested with a custom version of resistive-adc-touch driver, since it needs to be extended to make use of Z1 and Z2 channels. The X/Y are working without additional changes.

Jonathan writes: First set of new IIO device support, features and cleanup for the 5.8 cycle Usual mix of new drivers, new support in old drivers and lots of minor cleanup. Yaml conversions also continue to trickle in (plenty more to go!) New device support * ad7476 - Add ad7091 support (ID only) * ad9467 - New driver for this 200/250 MSPS adi-axi-adc and SPI attached ADC. * adi-axi-adc - New driver to support ADIs generic AXI ADC IP core, used to provide high speed interfaces to ADCs (JESD204B/C or parallel interfaces). Usually paired with a device using a slow configuration interface (spi etc) Includes DT bindings and some fixes for fpga headers. * bmg160 - Add support for BMI088 (ID only) * max1241 - New driver for this ADC. * st_sensors - Add support for LIS2HH12 accelerometer * sx9310 - New driver supporting sx9310 and sx9311 proximity sensors. Yaml DT binding conversions * rockchip-saradc (including adding some missing parts) * stm32-dac * tsl2563 * vcnl4000 Features * st_lsm6dsx - Add LIS3MDL as a possible sensor hub device. * vcnl4000 - Add new concept of near level (from DT) to provide to userspace which often needs to have some calibrated concept of 'near'. Cleanups, minor fixes etc. * core - Use snprintf for functions where strings are built and there is potential for overflow. - Correct docs to indicate mlock should not be used directly by drivers. - Fix up accidental dropping of a patch to use bitmap_zalloc. - Stop allowing enabling of buffers with no channels enabled. - Drop unused 'stufftoread' from iio_buffer. - Drop scan_el_attrs form iio_buffer as unused. - Reorder sanity checks in __iio_device_register to fail earlier. - Drop all the devm_ runregister / free functions from IIO as they were never used and encourage poor design. * dma-buffer - Tidy up includes. * dma-engine-buffer - Provide dev-managed allocator. - Fix an issue with printing a size_t * cross subsystem (kxsd9, bmg160, mpu3050, bmi160, mpu6050, bmc150) - Replace some unnecessary casts of error ptrs and whilst there. use the %pe printf parameter to print them in a more useful fashion. * cross subsystem - Drop casts in calls to regmap_bulk_read as they make no sense. - Use devm_platform_ioremap_resource to reduce boilerplate. - Fix typos in Analog Devices. * counters/104-quad - Add Syed Nayyar Waris as an additional maintainer. * ad7476 - Generate CONVST signal internally rather than requiring external trigger. Add sysfs read back as can now do so. - use devm_add_action_or_reset to tidy up error and remove handling. * ad7793 - Switch to read_avail from explicit attribute. Mostly done to avoid confusing people with a - sign (without surounding spaces) that was correct but checkpatch didn't like. * adis library - Add missing newlines at end of error messages. * adis16400 - Use DEFINE_DEBUGS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTR. * adis16460 - Use DEFINE_DEBUGS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTR. * ad_sigma_delta - Move some channel definitions into individual drivers to avoid having to deal with complex options. * ak8974 - Silence an error on deffered probe. * bmp280 - Harden against IRQ before registration. - Convert to read_avail instead of opencoding the equivalent. - Explicitly mark GPIO as optional. - Cleanup casts. - Remove line breaks from strings. * htts221 - Replace direct access to platform_data with dev_get_platdata(). - Use device properties rather than device tree ones to allow ACPI probing. - Casting cleanups. * intel_mrfld_adc - Don't use unaligned accessor for aligned data. * isl29125 - Reorder buer pre and post hooks to allow for coming core rework. * ltc2983 - Remove comp to bool. * max1363 - Stop using mlock from the iio_dev directly in favour of a local lock with clearly defined scope. * max30100 - Use generic device properties to allow ACPI probe. * mpu6050 - Convert to i2c_new_client_device. - Add debugfs register access. * st_lsm6dsx - Provide means of configuring full scale on slave device if supported. - Drop include of st_sensors header to get one value. Its not otherwise used by this driver. * st-sensors - Replace direct access to platform_data with dev_get_platdata(). - Casting cleanups. - Avoid splitting strings. * st_uvis25 - Casting cleanups. * tsl2563 - Typo fix. * tsl2772 - scnprintf in a non obvious string building usecase. Note also 'fixes' a wrong calculation of remaining space that couldn't actually cause any trouble as there was lots of room. * xilinx-xadc - Fix Lars-Peter spelling his own name wrong :) + additional typos. * tag 'iio-for-5.8a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (101 commits) iio: magnetometer: ak8974: Silence deferred-probe error Documentation: ABI: document IIO in_proximity_nearlevel file iio: vcnl4000: Export near level property for proximity sensor dt-bindings: iio: light: vcnl4000: Add proximity-near-level dt-bindings: iio: Introduce common properties for iio sensors dt-bindings: iio: vcnl4000: convert bindings to YAML format iio: Fix misspellings of "Analog Devices" iio: light: isl29125: fix iio_triggered_buffer_{predisable,postenable} positions iio: adc: fsl-imx25-gcq: Use devm_platform_ioremap_resource iio: adc: at91-adc: Use devm_platform_ioremap_resource iio: adc: sun4i-gpadc-iio: Use devm_platform_ioremap_resource iio:light:ltr501: Drop unnecessary cast of parameter in regmap_bulk_read iio:magn:mmc35240: Drop unnecessary casts of val parameter in regmap_bulk* iio:imu:mpu6050: Tidy up parameters to regmap_bulk functions. iio:chemical:bme680: Tidy up parameters to regmap_bulk_read iio:chemical:atlas-sensor: Drop unnecessary explicit casts in regmap_bulk_read calls iio:accel:mxc4005: Drop unnecessary explicit casts in regmap_bulk_read calls iio: imu: st_lsm6dsx: drop huge include in sensor-hub driver iio: buffer: drop devm_iio_kfifo_free() API call iio: buffer: drop devm_iio_hw_consumer_free() API call ...

iio: adc: ad9467: add support AD9467 ADC

2020-04-19T15:56:23+00:00

The AD9467 is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC). It is optimized for high performanceover wide bandwidths and ease of use. The product operates at a 250 MSPS conversion rate and is designed for wireless receivers, instrumentation, and test equipment that require a high dynamic range. The ADC requires 1.8 V and 3.3 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances. Since the chip can operate at such high sample-rates (much higher than classical interfaces), it requires that a DMA controller be used to interface directly to the chip and push data into memory. Typically, the AXI ADC IP core is used to interface with it.
