Please add a qualifier past the prefix "ufs:" in the patch subject to make it clear that this patch only modifies the UFS platform driver. Otherwise this patch looks good to me. Thanks, Bart.

Use of_property_present() to test for property presence rather than of_find_property(). This is part of a larger effort to remove callers of of_find_property() and similar functions. of_find_property() leaks the DT struct property and data pointers which is a problem for dynamically allocated nodes which may be freed.
