From 5a6976b1040a2f99ab84eddbfa7cd072ac5d10fc Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Wed, 18 Oct 2023 08:17:14 +0200 Subject: [PATCH] arm64: dts: rockchip: Add DFI to rk3588s 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.
