Using the STM drivers with kernel above 6.6 i.e 6.13

[jayakrishnan_k]

Hi,
im currently working on interfacing the STM mems sensors with Beagle Vahead board, im using a kernel version of 6.13 and i tried patching the STM MEMS IIO drivers from link. Im aware that the STM has confirmed the testing of the driver with kernel 6.6.

While patching i faced few errors ie mis match in the headders and i have successfully resolved them.
im able to boot the device and able to get the device node in the /sys/bus/iio/device  when interfacing the lps22df sensor.
when any other sensors (lsm6dsox, lisduxs12,lsm6dsv32) are interfaced on the same bus, im not able to detect the device. i have the same hardware set for lps22df  also. but in that case i was able to get the raw pressure and temperature data.

I want to understand the issue why it happens so.
i have mentioned the mininal properties on the i2c bus node in DTS file. and have omitted all the optional parameters.

have a look at the STM driver booting errors
