Subject[PATCH v2 15/15] dt-bindings: cpufreq: qcom-hw: Add bindings for 8998
Date
The OSM programming addition has been done under the
qcom,cpufreq-hw-8998 compatible name: specify the requirement
of two additional register spaces for this functionality.
This implementation, with the same compatible, has been
tested on MSM8998 and SDM630.
