Subject: [PATCH] devfreq: exynos-ppmu: use node names with hyphens
Devicetree naming convention requires device node names to use hyphens
instead of underscore, so Exynos5422 devfreq event name
"ppmu-event3-dmc0_0" should be "ppmu-event3-dmc0-0". Newly introduced
dtschema enforces this, however the driver still expects old name with
an underscore.
Add new events for Exynos5422 while still accepting old name for
backwards compatibility.
