If anyone has any objections, please let me know. ------------------ From: Xiaolei Wang [ Upstream commit 0a2b96e42a0284c4fc03022236f656a085ca714a ] If the tuning step is not set, the tuning step is set to 1. For some sd cards, the following Tuning timeout will occur. Tuning failed, falling back to fixed sampling clock So set the default tuning step.
