From 8cfda0df3a3020454848f55ed23a781169770c99 Mon Sep 17 00:00:00 2001 From: Sricharan R Date: Thu, 25 Jul 2019 12:41:30 +0200 Subject: dt-bindings: opp: Re-organise kryo cpufreq to use it for other nvmem based qcom socs The kryo cpufreq driver reads the nvmem cell and uses that data to populate the opps. There are other qcom cpufreq socs like krait which does similar thing. Except for the interpretation of the read data, rest of the driver is same for both the cases. So pull the common things out for reuse.
