[PATCH v2 11/16] ARM: tegra: Add the DFLL to Tegra124 device tree
From: Tuomas Tynkkynen <hidden>
Date: 2014-07-21 15:40:22
Also in:
linux-arm-kernel, linux-pm, linux-tegra, lkml
Subsystem:
the rest · Maintainer:
Linus Torvalds
The DFLL clocksource is a separate IP block from the usual
clock-and-reset controller, so it gets its own device tree node.
