2020-05-03iio: magnetometer: ak8974: Provide scalingLinus Walleij1-1/+44
The manual for the HSCDTD008A gives us a scaling for the three axis as +/- 2.4mT (24 Gauss) per axis. The manual for the AMI305 and AMI306 gives us a scaling for the three axis as +/- 12 Gauss per axis. Tests with the HSCDTD008A sensor, cat the raw values: $ cat in_magn_*_raw raw 45 189 -19 The scaling factor in in_magn_*_scale is 0.001464843, which gives: 0.065 Gauss 0.277 Gauss -0.027 Gauss The earths magnetic field is in the range of 0.25 to 0.65 Gauss on the surface according to Wikipedia, so these seem like reasonable values. Again we are guessing that the AK8974 has a 12 bit ADC, based on the similarity with AMI305 and AMI306.

2020-05-03iio: magnetometer: ak8974: Break out measurementLinus Walleij1-26/+40
This breaks out the measurement code to its own function so we can handle this without swirling it up with the big switch() statement inside ak8974_read_raw(). Keep a local s16 helper variable for the signed value coming out of the measurement before assigning it to the integer *val. The local variable makes the code easier to read and the compiler will optimize it if possible.

2020-05-03iio: magnetometer: ak8974: Correct realbitsLinus Walleij1-8/+37
The HSCDTD008A has 15 bits of actual ADC valie, and the AMI305 and AMI306 has 12 bits. Correct this by providing an extra parameter to the channel macro and define a separate set of channels for each variant of the chip. The resolution is the actual resolution of the internal ADC of the chip. The values are stored in a S16 in 2's complement so all 16 bits are used for storing (no shifting needed). The AMI305, AMI306 and HSCDTD008A valid bits are picked from respective datasheet. My best educated guess is that AK8974 is also 12 bits. The AK8973 is an 8 bit and earlier version, and the sibling drivers AMI305 and AMI306 are 12 bits, so it makes sense to assume that the AK8974 is also 12 bits.

2020-05-03iio: buffer: extend short-hand use for 'indio_dev->buffer'Alexandru Ardelean1-27/+34
This change is both cosmetic and a prequel to adding support for attaching multiple buffers per IIO device. The IIO buffer sysfs attrs are mostly designed to support only one attached buffer, and in order to support more, we need to centralize [in each attr function] the buffer which is being accessed. This also makes it a bit more uniform, as in some functions there is a short-hand 'buffer' variable and at the same time the 'indio_dev->buffer' is still access directly.

2020-05-03iio: chemical: Add support for external Reset and Wakeup in CCS811Manivannan Sadhasivam1-11/+94
CCS811 VOC sensor exposes nRESET and nWAKE pins which can be connected to GPIO pins of the host controller. These pins can be used to externally release the device from reset and also to wake it up before any I2C transaction. The initial driver support assumed that the nRESET pin is not connected and the nWAKE pin is tied to ground. This commit improves it by adding support for controlling those two pins externally using a host controller. For the case of reset, if the hardware reset is not available, the mechanism to do software reset is also added. As a side effect of doing this, the IIO device allocation needs to be slightly moved to top of probe to make use of priv data early.

The spi transfer length should hold the "real" burst length depending on the current burst mode configured in the device. Moreover, `extra_len` in `adis_burst` is made const and it should contain the smallest extra length necessary for a burst transfer.

positions The iio_triggered_buffer_{predisable,postenable} functions attach/detach poll functions. In most cases the iio_triggered_buffer_postenable() should be called first to attach the poll function, and then the driver can init the data to be triggered. In this case it's the other way around: the DMA code should be initialized before the attaching the poll function and the reverse should be done when un-initializing. To make things easier when removing the iio_triggered_buffer_postenable() & iio_triggered_buffer_predisable() functions from the IIO core API, the DMA code has been moved into preenable() for init, and postdisable() for uninit.

2020-04-25iio: adc: at91-sama5d2_adc: update for other trigger usageEugen Hristev1-70/+72
This change will allow the at91-sama5d2_adc driver to use other triggers than it's own. In particular, tested with the sysfs trigger. To be able to achieve this functionality, some changes were required: 1) Do not enable/disable channels when enabling/disabling the trigger. This is because the trigger is enabled/disabled only for our trigger (obviously). We need channels enabled/disabled regardless of what trigger is being used. 2) Cope with DMA : DMA cannot be used when using another type of trigger. Other triggers work through pollfunc, so we get polled anyway on every trigger. Thus we have to obtain data at every trigger. 3) When to start conversion? The usual pollfunc (store time from subsystem) would be in hard irq and this would be a good way, but current iio subsystem recommends to have it in the threaded irq. Thus adding software start code in this handler. 4) Buffer config: we need to setup buffer regardless of our own device's trigger. We may get one attached later. 5) IRQ handling: we use our own device IRQ only if it's our own trigger and we do not use DMA . If we use DMA, we use the DMA controller's IRQ.

2020-04-25iio: adc: at91-sama5d2_adc: handle unfinished conversionsEugen Hristev1-14/+48
It can happen that on IRQ trigger, not all conversions are done if we are enabling multiple channels. The IRQ is triggered on first EOC (end of channel), but it can happen that not all channels are done. This leads into erroneous reports to userspace (zero values or previous values). To solve this, in trigger handler, check if the mask of done channels is the same as the mask of active scan channels. If it's the same, proceed and push to buffers. Otherwise, use usleep to sleep until the conversion is done or we timeout. Normally, it should happen that in a short time fashion, all channels are ready, since the first IRQ triggered. If a hardware fault happens (for example the clock suddently dissappears), the handler will not be completed, in which case we do not report anything to userspace anymore. Also, change from using the EOC interrupts to DRDY interrupt. This helps with the fact that not 'n' interrupt statuses are enabled, each being able to trigger an interrupt, and instead only data ready interrupt can wake up the CPU. Like this, when data is ready, check in handler which and how many channels are done. While the DRDY is raised, other IRQs cannot occur. Once the channel data is being read, we ack the IRQ and finish the conversion. Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

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 ...
2020-04-19iio: magnetometer: ak8974: Silence deferred-probe errorDmitry Osipenko1-1/+6
It's not uncommon that voltage regulator becomes available later during kernel's boot process. This patch adds info message about unavailable regulators in a case of the deferred-probe error and also amends the error message with a error code.

2020-04-19iio: vcnl4000: Export near level property for proximity sensorGuido Günther1-0/+25
When an object can be considered close to the sensor is hardware dependent. Allowing to configure the property via device tree allows to configure this device specific value. This is useful for e.g. iio-sensor-proxy to indicate to userspace if an object is close to the sensor.
