Proposed example doesn't work on cameras:

# /utils/spi_id /dev/spidev0.0
response(7): 00 00 00 00 00 00 
# /utils/spi_id /dev/spidev1.0
response(7): ff ff ff ff ff ff 
# /utils/spi_id /dev/spidev1.1
response(7): ff ff ff ff ff ff

One approach could be parse dmesg output but needed more examples for different hardware:

original cv300
# dmesg | grep hisi_spi_nor.0
hisi-sfc hisi_spi_nor.0: lk=>8, 0x800000.
hisi-sfc hisi_spi_nor.0: mx25l12835f (16384 Kbytes)
hisi-sfc hisi_spi_nor.0: lk=>7, 0x400000.

Added XM specific ioctl calls to obtain SPI NOR chip name and id in 81d3e84

Also, ipc_chip_info has code to implement a basic dmesg regex finder which will be probably added further
