[PATCH 00/12] arm64: dts: qcom: Supply clock from cpufreq node to CPUs

[Manivannan Sadhasivam]

Hi,

As a follow-up of [1], this series adds support for supplying clock from
cpufreq node to CPUs for rest of the SoCs.

This series has been tested on SDM845, SM8450 and SC8280XP based boards.

Thanks,
Mani

[PATCH 06/12] arm64: dts: qcom: qdu1000: Supply clock from cpufreq node to CPUs

[Manivannan Sadhasivam]

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.
