From 07ee5e7c3ec00b30996160e9a378471872ea779e Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Fri, 9 May 2014 05:49:29 +0900 Subject: [PATCH] ARM: S3C24XX: convert s3c2410 to common clock framework Convert the machines using the s3c2410 to use the new driver based on the common clock framework instead of the legacy Samsung clock driver. As with the s3c244x, machines using the clkout output will need a fixup from someone with the hardware.
