From 040306a71663d98f1ca568b61010ee125d1e6501 Mon Sep 17 00:00:00 2001 From: Udo Schläpfer Date: Fri, 30 Jan 2015 22:47:30 +0100 Subject: iBasso DX50/DX90: User selectable freq scaling governor. Depends on http://gerrit.rockbox.org/r/#/c/1043/. This patch adds a new setting in Settings -> General -> System: Freq Scaling Governor Usable in Quickscreen and Shortcuts. Possible settings are: - Conservative: Slow frequency switching. - Ondemand or Interactive: Fast frequency switching. - Powersave: Allways lowest frequency. - Performance: Allways highest frequency. German translation provided. This may be genric for Android kernel based devices but is only enabled for iBasso Devices. Other maintainers may choose do adopt this.
