Move the IIO device allocation before the actual initialization of the chip to be more consistent with most IIO drivers and also to have the ability to use any driver specific data for the chip initialization. While at it, fix also a misaligned line. Signed-off-by:

Calibration data are located in contiguous-ish registers inside the chip. For that reason we can use bulk reads as is done as well in the BME68x Sensor API [1]. The arrays that are used for reading the data out of the sensor are located inside DMA safe buffer.

Add mutexes in the {read/write}_raw() functions of the device to guard the read/write of data from/to the device. This is necessary because for any operation other than temperature, multiple reads need to take place from the device. Even though regmap has a locking by itself, it won't protect us from multiple applications trying to read at the same time temperature and pressure since the pressure reading includes an internal temperature reading and there is nothing to ensure that this temperature+pressure reading will happen sequentially without any other operation interfering in the meantime.

The binding's documentation specifies that "As the line is active low, it should be marked GPIO_ACTIVE_LOW". However, in the driver, it was handled the opposite way. This commit sets the driver's behaviour in sync with the documentation Fixes: 722407a4 ("staging:iio:ad7606: Use GPIO descriptor API") Signed-off-by:
-
Guillaume Stols authored
gpiod_set_array_value was misused here: the implementation relied on the assumption that an unsigned long was required for each gpio, while the function expects a bit array stored in "as much unsigned long as needed for storing one bit per GPIO", i.e it is using a bit field. This leaded to incorrect parameter passed to gpiod_set_array_value, that would set 1 value instead of 3. It also prevents to select the software mode correctly for the AD7606B. Fixes: d2a415c8 ("iio: adc: ad7606: Add support for AD7606B ADC") Fixes: 41f71e5e ("staging: iio: adc: ad7606: Use find_closest() macro") Signed-off-by:

Nuno Sa authored
If there's only one possible scale, there's no way to change the Vref select in the device so avoid reading the register in ad9467_get_scale(). In this case, it makes no sense to provide the .read_available() callback nor allowing for writing the scale attribute. Note this is in preparation for supporting a new device that only has one possible scale. Signed-off-by:

Add new variables to the per chip info structure: * test_points: Number of valid test points for calibration; * has_dco_invert: Supports inverting DCO (Data clock output) polarity; * dco_en: Specicic mask to enable DCO delays. This is in preparation for supporting new parts with subtle differences in how to configure the hardware. Note that with the new test_points variable, we also add a new calib_map_size to 'struct ad9467_state' so we know our map size depending on how many test points we have and if we can run the calibration in the inverted state or not.

Nuno Sa authored
The calibration process mixes the support for calibrating multiple channels with only having one channel. Some paths do have 'num_channels' into account while others don't. As of now, the driver only supports devices with one channel so the above is not really a problem. That said, we'll add support for devices with more than one channel, hence let's properly make the calibration process to work with it. Signed-off-by:
