From 960ddf70cc11024e6e9dac206316d0160e00a77d Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Fri, 11 Dec 2020 13:58:46 +0000 Subject: drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCs Since at91_soc_init is called unconditionally from atmel_soc_device_init, we get the following warning on all non AT91 SoCs: " AT91: Could not find identification node" Fix the same by filtering with allowed AT91 SoC list.
