From ceb7d77d6f81e63af6e7af83f8d58b2ac4fc8b9d Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 15 Mar 2016 18:09:15 -0500 Subject: ARM: OMAP5/DRA7: Split iodelay functionality into sub steps Since many platforms may need different pad configuration required depending on variation of the platform with minor deltas, it is easier to maintain a sub step based approach to allow for pin mux and iodelay configuration which may depend on the platform variations and need to be done in IO isolation. While we retain the older __recalibrate_iodelay function which provides a ready sequencing, __recalibrate_iodelay_start and __recalibrate_iodelay_end may be alternatively used now and the callers will be responsible for the correct sequencing of operations.
