From 3811746ed9b48c8a538fc6a6edfe91aaf9acb76a Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Tue, 25 Feb 2020 14:40:42 +0100 Subject: [PATCH] nand: raw: zynq: Do not try to probe driver if nand flash is disabled There is no reason to continue when DT status property indicates that NAND flash is disabled. But that means that NOR flash should be present that's why try it find it out.
