From f56804453a7f41a37d14f7ad325af6231a84a82a Mon Sep 17 00:00:00 2001 From: Lukasz Luba Date: Mon, 27 Nov 2023 08:15:11 +0000 Subject: arm64: dts: rockchip: Add dynamic-power-coefficient to rk3399 GPU Add dynamic-power-coefficient to the GPU node. That will create Energy Model for the GPU based on the coefficient and OPP table information. It will enable mechanism such as DTMP or IPA to work with the GPU DVFS. In similar way the Energy Model for CPUs in rk3399 is created, so both are aligned in power scale. The maximum power used from this coefficient is 1.5W at 600MHz.
