From ba3fae06c7a4e80ab9d48a8a045b352da97cf23d Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 1 Feb 2017 10:41:43 +0100 Subject: ARM/clk: move the ICST library to drivers/clk This moves the ICST clock divider helper library from arch/arm/common to drivers/clk/versatile so it is maintained with the other clock drivers. We keep the structure as a helper library intact and do not fuse it with the clk-icst.c Versatile ICST clock driver: there may be other users out there that need to use this library for their clocking, and then it will be helpful to keep the library contained. (The icst.[c|h] files could just be moved to drivers/clk/lib or a similar location to share the library.)
