Subject: [U-Boot] [PATCH 1/2] exynos: clock: fixed that cfg is set to wrong value.
Date: Thu, 06 Feb 2014 14:20:10 +0900 [thread overview]
Message-ID: <52F31B8A.6010002@samsung.com> (raw)
From: Inha Song <ideal.song@samsung.com>
This patch fixed that cfg value is set to wrong value.
Because it didn't read the related register.
(Based on Inha's patch : "arm:exynos:add missing readl")
