Common #defines have been moved to "linux/fsl/ftm.h". Thus making use of
this file.
Also FTM_SC_CLK_SHIFT has been renamed to FTM_SC_CLK_MASK_SHIFT.

The polling/32bit signed version has been dropped, as not needed and
no other driver is doing that.
Patrick Havelange (7):
include/fsl: add common FlexTimer #defines in a separate header.

It is based on the same behavi
Hi Jonathan,
Thanks for your comments, I'll make a new version of the patch based
