| Subject: [PATCH] ARM: dts: r8a7779: Add device node for ARM global timer |
| |
| commit 8443ffd1bbd5be74e9b12db234746d12e8ea93e2 upstream. |
| |
| 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. |
