2024-07-29iio: dac: ti-dac7311: Add check for spi_setupChen Ni
Add check for the return value of spi_setup() and return the error if it fails in order to catch the error. Signed-off-by: Chen Ni <nichen@iscas.ac.cn> Link: https://patch.msgid.link/20240705084250.3006527-1-nichen@iscas.ac.cn Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2024-07-29iio: adc: ad7606: switch mutexes to guardGuillaume Stols

2024-07-29iio: adc: ad7606: fix standby gpio state to match the documentationGuillaume Stols
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: 722407a4e8c0 ("staging:iio:ad7606: Use GPIO descriptor API") Signed-off-by: Guillaume Stols <gstols@baylibre.com> Reviewed-by: Nuno Sa <nuno.sa@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2024-07-29iio: adc: ad7606: fix oversampling gpio arrayGuillaume Stols
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: d2a415c86c6b ("iio: adc: ad7606: Add support for AD7606B ADC") Fixes: 41f71e5e7daf ("staging: iio: adc: ad7606: Use find_closest() macro") Signed-off-by: Guillaume Stols <gstols@baylibre.com> Reviewed-by: Nuno Sa <nuno.sa@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2024-07-29iio: adc: ad9467: don't allow reading vref if not availableNuno Sa
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.

2024-07-29iio: adc: ad9467: add new chip_info variablesNuno Sa
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.

2024-07-29iio: adc: ad9467: support multiple channels calibrationNuno Sa
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.

2024-07-29iio: core: add accessors 'masklength'Nuno Sa
'masklength' is supposed to be an IIO private member. However, drivers (often in trigger handlers) need to access it to iterate over the enabled channels for example (there are other reasons). Hence, a couple of new accessors are being added: * iio_for_each_active_channel() - Iterates over the active channels; * iio_get_masklength() - Get length of the channels mask. The goal of these new accessors is to annotate 'masklength' as private as soon as all drivers accessing it are converted to use the new helpers.

2024-07-29task_work: make TWA_NMI_CURRENT handling conditional on IRQ_WORKLinus Torvalds
The TWA_NMI_CURRENT handling very much depends on IRQ_WORK, but that isn't universally enabled everywhere. Maybe the IRQ_WORK infrastructure should just be unconditional - x86 ends up indirectly enabling it through unconditionally enabling PERF_EVENTS, for example. But it also gets enabled by having SMP support, or even if you just have PRINTK enabled. But in the meantime TWA_NMI_CURRENT causes tons of build failures on various odd minimal configs. Which did show up in linux-next, but despite that nobody bothered to fix it or even inform me until -rc1 was out.
