| | * | iio: adc: sun4i: add THERMAL dependencyArnd Bergmann2017-04-021-0/+1

When the thermal code is a module, we can still build the adc driver as a module, too.

| | * | iio: adc: cpcap: Add minimal support for CPCAP PMIC ADCTony Lindgren2017-03-303-0/+1019

This PMIC has ADCs that are used for battery charging and USB PHY VBUS and ID pin detection. Unfortunately the only documentation for this ADC seems to be the Motorola mapphone Linux kernel tree. I have tested that reading raw and scaled values works, but I have not used the timed sampling that the ADC seems to support. Let's add a minimal support for it so we can eventually provide IIO channels for the related battery charging and USB PHY drivers.

But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

| * | iio: adc: add support for Allwinner SoCs ADCQuentin Schulz2017-03-083-0/+631
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Allwinner SoCs all have an ADC that can also act as a touchscreen controller and a thermal sensor. This patch adds the ADC driver which is based on the MFD for the same SoCs ADC. This also registers the thermal adc channel in the iio map array so iio_hwmon could use it without modifying the Device Tree. This registers the driver in the thermal framework. The thermal sensor requires the IP to be in touchscreen mode to return correct values. Therefore, if the user is continuously reading the ADC channel(s), the thermal framework in which the thermal sensor is registered will switch the IP in touchscreen mode to get a temperature value and requires a delay of 100ms (because of the mode switching), then the ADC will switch back to ADC mode and requires also a delay of 100ms. If the ADC readings are critical to user and the SoC temperature is not, this driver is capable of not registering the thermal sensor in the thermal framework and thus, "quicken" the ADC readings. This driver probes on three different platform_device_id to take into account slight differences (registers bit and temperature computation) between Allwinner SoCs ADCs.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tiadc_irq_h(int irq, void *private) function is handling FIFO overruns by clearing flags, disabling and enabling the ADC to recover. If the ADC is running in continuous mode a FIFO overrun happens regularly. If the disabling of the ADC happens concurrently with a new conversion. It might happen that the enabling of the ADC is ignored by the hardware. This stops the ADC permanently. No more interrupts are triggered. According to the AM335x Reference Manual (SPRUH73H October 2011 - Revised April 2013 - Chapter 12.4 and 12.5) it is necessary to check the ADC FSM bits in REG_ADCFSM before enabling the ADC again. Because the disabling of the ADC is done right after the current conversion has been finished. To trigger this bug it is necessary to run the ADC in continuous mode. The ADC values of all channels need to be read in an endless loop. The bug appears within the first 6 hours (~5.4 million handled FIFO overruns). The user space application will hang on reading new values from the character device.

The code is based on the public S805 (Meson8b) and S905 (GXBB) datasheets (see [0] and [1]), as well as by reading (various versions of) the vendor driver and by inspecting the registers on the vendor kernels of my testing-hardware. Currently the GXBB, GXL and GXM SoCs are supported. GXBB hardware has 10-bit ADC resolution, while GXL and GXM have 12-bit ADC resolution. The code was written to support older SoCs (Meson8 and Meson8b) as well, but due to lack of actual testing-hardware no of_device_id was added for these. Two "features" from the vendor driver are currently missing: - the vendor driver uses channel #7 for calibration (this improves the accuracy of the results - in my tests the results were less than 3% off without calibration compared to the vendor driver). Adding support for this should be easy, but is not required for most applications. - channel #6 is connected to the SoCs internal temperature sensor. Adding support for this is probably not so easy since (based on the u-boot sources) most SoC versions are using different registers and algorithms for the conversion from "ADC value" to temperature. Supported by the hardware but currently not supported by the driver: - reading multiple channels at the same time (the hardware has a FIFO buffer which stores multiple results) - continuous sampling (this would require a way to enable this individually because otherwise the ADC would be drawing power constantly) - interrupt support (similar to the vendor driver this new driver is polling the results. It is unclear if the IRQ-mode is supported on older (Meson6 or Meson8) hardware as well or if there are any errata) [0] http://dn.odroid.com/S805/Datasheet/S805_Datasheet%20V0.8%2020150126.pdf [1] http://dn.odroid.com/S905/DataSheet/S905_Public_Datasheet_V1.1.4.pdf Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Tested-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

It's shaping to be another fairly busy cycle. Lots more on the way! New device support * ads7950 - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954, ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs. * cm3605 - New driver for this light sensor and proximity sensor which is an analog part with some additional digital controls. * hx711 - New driver. Core new stuff * Gravity sensor type. This is a processed datastream in which the device will try to work out which way is down. * Split the buffer.h file into two parts. One provides the interface to 'use' a buffer, the second provides the internals of the buffer functionality as needed by implementations of buffers. - Move documentation inline so as to allow use of private: tag when generating documentation. - Add some utility functions for the few things that are directly done with the buffers. - Stop exporting functions that no-one uses outside of the core code. - Push docs down by the code in the c file where they should have always been. - Fix typo in kernel-doc for buffer. - push down some includes that were previously happening implicitly. - stop enabling the timestamp of the dummy device. Features and cleanups * ad5592r - ACPI support * ad5593r -ACPI support. * ad5933 - Fix a false comment about size of a particular register. * ad7150 - replace S_IRUGO | S_IWUSR with 0644. I'm not that keen on these patches in general, but as it was nicely presented I took this one anyway. As a general rule will only take these as part of a larger driver cleanup. - don't eat an error but rather reutnr it in the write_event_config callback. * ad7606 - replace non standard range attibute with _scale * ade7753 - use usleep_range for short sleeps * ade7754 - use usleep_range for short sleeps * ade7758 - use usleep_range for short sleeps * ade7759 - use usleep_range for short sleeps * ade7854 - use usleep_range for short sleeps * adis16201 - fix description * adis16203 - fix description - fix copyright year * adis16209 - fix description * adt7316 - Add braces to arms of if else statement (for consistency) - Alignment fixes. * axp288 - Fix up an issue with accidental overwrites of data. * bmi160 - add deivce tables for i2c and spi to support correctly identifying the full dt name (including manufacturer). - device tree binding. * bmp280 - use usleep_range for short sleeps. * cm3232 - return error from cm3232_reg_init rather than eating it if the last write fails. * dummy driver - remove a semicolor found at end of a function defintition. * exynos-adc - use usleep_range for short sleeps. * hid-sensor (accel) - Add timestamp support. The hardware can provide timestamps so lets support them. If not fall back to timestamps estimated in kernel. * hid-sensor (light) - Add a duplicate ID for the light channels so as to keep existing interface whilst also using the more standard IIO interface. * hts221 - acpi probing * imx25-gcq - Add a macro call to allow this driver to be automatically loaded. * isl29028 - reorganise code to avoid deep nesting of if statements. - move chip test and default regs into a function suitable or sharing with power management code. - tidy up some code alignment. * lidar-lite-v3 - introduce compatible strings that make it clear Garmin have consideral friends. * mma8452 - avoid returning signed value when unsigned is appropriate * spmi-vadc - Update function for generic voltage conversion to take into account that different channels on this device should be handled differently. - Rework code to allow per channel voltage scaling and support the standard options for this hardware. - Fixup three minor issues with the above patches for this part. These all effect test builds rather than the native builds for the part, but good to clean them up anyway. * st_sensors - support device matching from the ACPI DST tables. - acpi based probing for accelerometers - acpi based probing for pressure sensors - Allow pressure sensors to read negative values. - Export sampling frequency for lps25h and lps331ap. - Add support for the old DT bindings from the period when these deivces were often supported through windows. Docs fixup: * typo in sysfs-bus-iio
