Subject: [PATCH 6/7] ARM: dts: sun6i: Add required ahb1 clock parent and rates for dma controller
Date: Sat, 6 Sep 2014 18:47:27 +0800 [thread overview]
Message-ID: <1410000448-9999-7-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1410000448-9999-1-git-send-email-wens@csie.org>
The DMA controller requires AHB1 bus clock to be clocked from PLL6.
