From fc7258948c4a9e5dd2670adfcc80b13c621fbcd1 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Wed, 15 Feb 2023 12:33:56 +0530 Subject: [PATCH] arm64: dts: qcom: sm8150: 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.
