[PATCH v8 26/26] arm64: dts: rockchip: rk3588s: Add DFI

From: Sascha Hauer
Date: Wed Oct 18 2023 - 02:18:21 EST


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.
