From 86d90fd95bbc3b3fdc2ef0507b7324cd1d0a358b Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 8 Sep 2020 19:24:46 +0900 Subject: PM / devfreq: Change prototype of devfreq_get_devfreq_by_phandle function Previously, devfreq core support 'devfreq' property in order to get the devfreq device by phandle. But, 'devfreq' property name is not proper on devicetree binding because this name doesn't mean the any h/w attribute. The devfreq core hand over the right to decide the property name for getting the devfreq device on devicetree. Each devfreq driver will decide the property name on devicetree binding and pass the their own property name to devfreq_get_devfreq_by_phandle function.
