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.
