From b64c11166e3a9d8f832537581832844beb974cb1 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Fri, 11 Dec 2020 13:58:46 +0000 Subject: [PATCH] drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCs commit caab13b4960416b9fee83169a758eb0f31e65109 upstream. 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.
