Subject: [PATCH 2/2] ARM: dts: enable init rate for clock
Date: Tue, 7 Oct 2014 17:33:58 +0800 [thread overview]
Message-ID: <1412674438-26160-3-git-send-email-kever.yang@rock-chips.com> (raw)
In-Reply-To: <1412674438-26160-1-git-send-email-kever.yang@rock-chips.com>
We need to initialize PLL rate and some of bus clock rate while
kernel init, for there is no other module will do that.
