2025-02-03iio: dac: adi-axi-dac: modify stream enableAngelo Dureghello
Change suggested from the AXI HDL team, modify the function axi_dac_data_stream_enable() to check for interface busy, to avoid possible issues when starting the stream.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Merge from Jonathan: IIO: 2nd set of fixes for the 6.13 cycle. Given timing so late in cycle and that they are all confined to specific drivers, it is fine for these to go upstream early in the 6.14 cycle. hid-sensors - Handle processed attention channel rather than just returning an error. adi,ad3552r - Fix output ranges for ad3541r and ad3542r. - Clear the reset status flag so that we can pick up any resets during operation. adi,ad5791 - Fix a misleading dt binding example where the sense of the interrupt was reversed. adi,ad7606 - Fix some hard coded offsets that should be taking the number of channels on a particular part into account. These were missed due to some racing changes. ams,as73211 - Fix an off by one in optimized path for just reading the colour channels. bosch,bme680 - Fix type of variable passed as pointer, ensuring it works on big endian systems and doesn't expose uninitialized data. * tag 'iio-fixes-for-6.13b' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: iio: dac: ad3552r-hs: clear reset status flag iio: dac: ad3552r-common: fix ad3541/2r ranges iio: chemical: bme680: Fix uninitialized variable in __bme680_read_raw() iio: light: as73211: fix channel handling in only-color triggered buffer dt-bindings: iio: dac: ad5791: ldac gpio is active low iio: hid-sensor-prox: Fix invalid read_raw for attention iio: adc: ad7606: Fix hardcoded offset in the ADC channels
2025-01-12iio: dac: ad3552r-hs: clear reset status flagAngelo Dureghello
Clear reset status flag, to keep error status register clean after reset (ad3552r manual, rev B table 38). Reset error flag was left to 1, so debugging registers, the "Error Status Register" was dirty (0x01). It is important to clear this bit, so if there is any reset event over normal working mode, it is possible to detect it.

Fix ad3541/2r voltage ranges to be as per ad3542r datasheet, rev. C, table 38 (page 57). The wrong ad354xr ranges was generating erroneous Vpp output. In more details: - fix wrong number of ranges, they are 5 ranges, not 6, - remove non-existent 0-3V range, - adjust order, since ad3552r_find_range() get a wrong index, producing a wrong Vpp as output.

2024-12-28iio: dac: Support ROHM BD79703 DACMatti Vaittinen
The ROHM BD79703 is a 6 channel digital to analog converter. Based on the data-sheet examples the hardware would support setting the DAC word without changing the actual output. The data-sheet is not too specific on how the enabling the output of new voltage set by DAC should be done - hence this is not implemented by the driver. The BD79703 would also support two specific "PULL_DOWN" modes. These aren't currently supported by the driver either. Add a very basic support for controlling the channel outputs one-by-one.

2024-12-28iio: dac: ad7293: enable power before resetDavid Lechner
Change the order of regulator enable and reset so that power supplies are turned on before touching the reset line. Generally, chips should have the VDRIVE supply enabled before applying voltage on any pins. While we are at it, remove the voltage level checks. If the power supplies are not supplying the correct voltage, this is a hardware design problem, not a software problem.
