From 2bdb053a8119355eada46dfab88782449a26b39d Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 3 Sep 2010 12:35:37 +0200 Subject: mtd: davinci: relax a timeout for ECC-initialization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Sudhakar found out that 100µs are enough. Sadly, his updated patch was overlooked and an older version still using 100ms was merged. Fix this.
