From f70409aff3a10e22ff9c66f87e9cbc3de7cbd7f7 Mon Sep 17 00:00:00 2001 From: Minkyu Kang Date: Tue, 24 Aug 2010 15:51:55 +0900 Subject: ARMV7: S5P: separate the peripheral clocks Because of peripheral devices can select clock sources, separate the peripheral clocks. (pwm, uart and so on) It just return the pclk at s5pc1xx SoC, but s5pc210 SoC must be calculated by own clock register setting.
