From fee9c6d8f098f7054f97ec1dbcfb42a2a3238f23 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Wed, 5 May 2021 23:37:40 +0200 Subject: [PATCH] mtd: rawnand: Avoid accessing NV-DDR timings from legacy code Legacy code should not benefit from newer features, especially in helpers that have been deprecated for a very long time. People who want NV-DDR support must migrate their driver to the ->exec_op() API.
