Subject: ARM: dts: sh73a0: Add device node for ARM global timer
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=df1a0aac0a533e6f3ff843c64a9a0d3b7f37c89c;p=linux.git

ARM: dts: sh73a0: Add device node for ARM global timer

Add a device node for the global timer, which is part of the Cortex-A9
MPCore.

The global timer can serve as an accurate (3 ns) clock source for
scheduling and delay loops.
