Subject: ARM: tegra: Add the DFLL to Tegra124 device tree
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bf9d026775796bec30895cab080baf37b70bc3b3;p=linux-beck.git

ARM: tegra: Add the DFLL to Tegra124 device tree

The DFLL clocksource is a separate IP block from the usual
clock-and-reset controller, so it gets its own device tree node.
