Hello,
I'm confused by the modalias'es created by OF devices, e.g.:
# cat /sys/devices/f0000000.soc5200/f0000f00.spi/modalias
of:NspiT<NULL>Cfsl,mpc5200b-spiCfsl,mpc5200-spi
First of all, the string "<NULL>" looks like an error.
I could then dynamically load a driver module for the SPI using:
# modprobe `cat sys/devices/f0000000.soc5200/f0000f00.spi/modalias`
This does make sense for the SPI device, but there are OF devices which
cannot really be used by a module driver, e.g.:
# cat /sys/devices/f0000000.soc5200/f0000500.interrupt-controller/modalias
of:Ninterrupt-controllerT<NULL>Cfsl,mpc5200b-picCfsl,mpc5200-pic
The same for localbus, cdm, etc. Does it make sense for these
to create a modalias file?
Likely I have missed something. Thanks for clarification.
Wolfgang.
