Subject: arm64: dts: qcom: sm8550: Supply clock from cpufreq node to CPUs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1b0911fe3edb0895c43db4c19729b3c300028189;p=linux.git

arm64: dts: qcom: sm8550: 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.
