Subject: [U-Boot] [PATCH v3 3/5] ARM: cpu: at91: clean up peripheral clock code
Date: Thu, 10 Dec 2015 10:20:51 +0800 [thread overview]
Message-ID: <1449714053-26416-4-git-send-email-wenyou.yang@atmel.com> (raw)
In-Reply-To: <1449714053-26416-1-git-send-email-wenyou.yang@atmel.com>
Due to introducing the new peripheral clock handle functions,
use these functions to clean up the duplicated code.
Meanwhile, remove unneeded header file include, at91_pmc.h.
