From 2cec67865b0c5f5ce3c2db1a1addf33b24bbf044 Mon Sep 17 00:00:00 2001 From: Masaharu Hayakawa Date: Thu, 1 Nov 2018 00:00:43 +0100 Subject: [PATCH] mmc: tmio: delete wait in tuning process MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The manual does not contain information that a wait is needed in the tuning process, this might be a leftover from early development. Removing the wait don't have any effect on operation so delete the wait to shorten the initialization time.
