From 02bdbf7d09c059b16047e3d4a05e6d584dd993b6 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 8 Sep 2020 19:24:47 +0900 Subject: PM / devfreq: event: Change prototype of devfreq_event_get_edev_by_phandle function Previously, devfreq core support 'devfreq-events' property in order to get the devfreq-event device by phandle. But, 'devfreq-events' property name is not proper on devicetree binding because this name doesn't mean the any h/w attribute. The devfreq-event core hand over the rights to decide the property name for getting the devfreq-event device on devicetree. Each devfreq-event driver will decide the property name on devicetree binding and then pass the their own property name to devfreq_event_get_edev_by_phandle function. And change the prototype of devfreq_event_get_edev_count function because of used deprecated 'devfreq-events' property.
