Date: Fri, 11 Dec 2020 10:31:43 +0000 From: Sudeep Holla <sudeep.holla@....com> To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Cc: Sudeep Holla <sudeep.holla@....com>, Nicolas Ferre <nicolas.ferre@...rochip.com>, Alexandre Belloni <alexandre.belloni@...tlin.com>, Ludovic Desroches <ludovic.desroches@...rochip.com> Subject: [PATCH] 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.
