[RFC PATCH 0/3] Support round phase stuff for clock driver

From: Shawn Lin

clk_set_phase is probably most used for sample tuning stuff, and
the caller will check whether finding a good degree or not to decide
how to implement the algorithm for catching the best sample window. Not
all of the phases are supportted by clock phase generator. So the drivers
which call clk_set_phase may result in setting the phase which is not
requestted, which will fininally makes the tuning result different.
Especially for the cross-platform drivers, they can be used for different
Socs, so it must care the actual phase supported by different clock phase

This RFC patchset introduces new API for phase stuff which parallels rate stuff
to meet the requirement.

Based on tag of v4.5-rc5

clk: add clk_round_phase support
clk: add clk_hw_set_phase_range support
