Subject: [RESEND PATCH v5 1/4] dt-bindings: devfreq: rk3399_dmc: Add rockchip, pmu phandle.

Message-ID: <20210308233858.24741-1-daniel.lezcano@linaro.org> (raw)

From: Enric Balletbo i Serra <enric.balletbo@collabora.com>

The Rockchip DMC (Dynamic Memory Interface) needs to access to the PMU
general register files to know the DRAM type, so add a phandle to the
syscon that manages these registers.
