From 458f3933bb8a72c2c4a2751009152d83ac71c23b Mon Sep 17 00:00:00 2001 From: Ivan Khoronzhuk Date: Tue, 17 Dec 2013 15:38:12 +0200 Subject: [PATCH] mtd: nand: davinci: reuse driver for Keystone arch The Keystone arch has compatible nand device, so reuse it. In case with Keystone it depends on TI_AEMIF because AEMIF driver is responsible to set timings.
