Date: Fri, 26 Feb 2016 13:08:10 +0800 From: Shawn Lin <shawn.lin@...k-chips.com> To: Stephen Boyd <sboyd@...eaurora.org>, Michael Turquette <mturquette@...libre.com> Cc: linux-kernel@...r.kernel.org, linux-clk@...r.kernel.org, Shawn Lin <shawn.lin@...k-chips.com> Subject: [RFC PATCH 0/3] Support round phase stuff for clock driver 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 generators. This RFC patchset introduces new API for phase stuff which parallels rate stuff to meet the requirement.
