From a081546de93b8fc3bbfe33e61e6dfa12eda35c24 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sun, 14 Mar 2021 20:15:01 +0800 Subject: net: tsec: Support property from the subnode "queue-group" At present the tsec driver uses a non-standard DT bindings to get its base / size. The upstream Linux kernel seems to require the base / size to be put under a subnode of the eTSEC node with a name prefix "queue-group". This is not documented in the kernel DT bindings, but it looks every dtsi file that contains the eTSEC node was written like this. This commit updates the tsec driver to handle this case.
