Subject: [PATCH AUTOSEL 4.14 088/186] ARM: dts: r8a7779: Add device node for ARM global timer
Date: Fri, 14 Feb 2020 11:15:37 -0500	[thread overview]
Message-ID: <20200214161715.18113-88-sashal@kernel.org> (raw)
In-Reply-To: <20200214161715.18113-1-sashal@kernel.org>

From: Geert Uytterhoeven <geert+renesas@glider.be>

[ Upstream commit 8443ffd1bbd5be74e9b12db234746d12e8ea93e2 ]

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

The global timer can serve as an accurate (4 ns) clock source for
scheduling and delay loops.
