From 28b69f64886c89d463ebe380f87f858f7362be36 Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Wed, 7 Sep 2016 15:18:23 +0530 Subject: spi: ti_qspi: Remove unnecessary udelay for AM437x This udelay() was added as an HACK and is no longer required. All read/write/erase operations work fine even without this delay. Hence, remove the udelay() call. Tested read/write/erase operation on AM437x SK. Also tested QSPI Boot.
