From c38758e3d574380ccfa583793be14c1cc8a322ff Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 6 Aug 2020 20:20:54 +0200 Subject: cpufreq: s3c24xx: move low-level clk reg access into platform code Rather than have the cpufreq drivers touch include the common headers to get the constants, add a small indirection. This is still not the proper way that would do this through the common clk API, but it lets us kill off the header file usage.
