From 8a8845e07b1164792a4dd5ad4d333d793828b366 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Thu, 17 Nov 2022 11:01:43 +0530 Subject: [PATCH] arm64: dts: qcom: sm8450: Supply clock from cpufreq node to CPUs Qualcomm platforms making use of CPUFreq HW Engine (EPSS/OSM) supply clocks to the CPU cores. But this relationship is not represented in DTS so far. So let's make cpufreq node as the clock provider and CPU nodes as the consumers. The clock index for each CPU node is based on the frequency domain index.
