Subject: ARM: dts: Add minimal clocks for dm814x
X-Git-Tag: android-x86-6.0-r1~819^2~4^2~33
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=25515b630c3c49945953cc048d6051441ac220d2;p=android-x86%2Fkernel.git

ARM: dts: Add minimal clocks for dm814x

Use fixed clocks until we have a clock driver for the PLL.
The mux and divider composite clocks work the same way
as on dm816x and am335x.
