Perhaps if you instead make ufshcd platform_device_register_data() the
bsg device you would solve the probe ordering, the remove will be
symmetric and module autoloading will work as well (although then you
need a MODULE_ALIAS of platform:device-name).
Hi Bjorn,
From Documentation/driver-api/driver-model/platform.rst:
"Platform devices are devices that typically appear as autonomous
entities in the system. This includes legacy port-based devices and
host bridges to peripheral buses, and most controllers integrated
into system-on-chip platforms. What they usually have in common
is direct addressing from a CPU bus. Rarely, a platform_device will
be connected through a segment of some other kind of bus; but its
registers will still be directly addressable."
Do you agree that the above description is not a good match for the
ufs-bsg kernel module?
Thanks,
Bart.
Hi Bart,
I missed this one.
How about making it a plain device and add it from ufs driver?
Thanks,
Can Guo.
