[PATCH 3/7] dt-bindings: devfreq: event: rockchip,dfi: add rk3576

[Sebastian Reichel]

From: Nicolas Frattaroli <nicolas.frattaroli@xxxxxxxxxxxxx>

The RK3576 has DFI hardware for monitoring the DDR's bandwidth much
like other rockchip SoCs do. Unlike the RK3588 however, it only has two
memory channels, so only two per-channel pclks for DFI.

Add a compatible for this SoC's variant, and add it to the conditionals
at the bottom of the bindings file.
