I'm have the rpi zero w
uname -a
Linux raspberrypi 5.10.103+ #1529 Tue Mar 8 12:19:18 GMT 2022 armv6l GNU/Linux
I'm have the mux device pca9548, pwm pca9685a and mpu6050. My config(/boot/config.txt):
dtparam=i2c_arm=on
dtoverlay=i2c-mux,pca9548,addr=0x70
dtoverlay=i2c-pwm-pca9685a
dtoverlay=mpu6050
But for mpu6050 IIO not present. My boot log

If direct connect mpu6050 to the i2c IIO present What I'm doing wrong?
