[PATCH] tee: optee: Populate child nodes in probe function

From: Ludvig Pärsson
Date: Wed Nov 09 2022 - 11:07:31 EST


Currently there is no dependency between the "linaro,scmi-optee" driver
and the tee_core. If the scmi-optee driver gets probed before the
tee_bus_type is initialized, then we will get an unwanted error print.

This patch enables putting scmi-optee nodes as children to the optee
node in devicetree, which indirectly creates the missing dependency.
