The AD9548 configuration is done as part of the Linux driver initialization. I'm looking the way how to modify AD9548 registers from the Linux dynamically for precise frequency adjustment.
I see devices:
# cat /proc/devices
I tried create the device for write and read to i2c-spi bridge:
mknod /dev/spidev32766.2 c 153 32766
But I got an error during opening device /dev/spidev32766.2 from the user space application programm.
Do you have any solution for communication with AD ICs?
