    Subject[PATCH v5 25/25] arm64: dts: rockchip: rk3588s: Add DFI
    Date
    The DFI unit can be used to measure DRAM utilization using perf. Add the
    node to the device tree. The DFI needs a rockchip,pmu phandle to the pmu
    containing registers for SDRAM configuration details. This is added in
    this patch as well.
