[PATCH v2 1/3] devfreq: exynos-ppmu: use node names with hyphens

From: Krzysztof Kozlowski <hidden>
Date: 2021-09-20 07:18:02
Also in: linux-arm-kernel, linux-pm, linux-samsung-soc, lkml
Subsystem: device frequency (devfreq), device frequency event (devfreq-event), the rest · Maintainers: MyungJoo Ham, Kyungmin Park, Chanwoo Choi, Linus Torvalds

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.
