Subject: [PATCH v2 1/3] devfreq: exynos-ppmu: use node names with hyphens
Date: Mon, 20 Sep 2021 09:17:51 +0200	[thread overview]
Message-ID: <20210920071753.38560-1-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210920071540.38337-1-krzysztof.kozlowski@canonical.com>

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.
