Hi Rob, Arnd,
There's a push to place all firmware related device node under
/firmware/ node. However all the associated drivers are dealing with
device creation in their own ways. For example, qcom_scm, optee and
meson-sm drivers deal with the node in their own way. The SCMI drivers
I am about to add also needs to do the same. This small series is to
make it generic so that all the users of /firmware/ node need not
repeat the same.
There was concern that /firmware in DT is fit for /sys/firmware in sysfs.
IMO anything exposed to userspace from such firmware interface must
be in "/sys/firmware", but I don't see any issue with kernel handling
them as platform device/driver internally.
Sudeep Holla (4):
of: platform: populate /firmware/ node from
of_platform_default_populate_init()
firmware: qcom_scm: drop redandant of_platform_populate
drivers: tee: rework optee_driver_{init,exit} to use platform device
firmware: meson-sm: rework meson_sm_init to use
module_platform_driver_probe
