From 729eeea56576b9dc1613460b3733e6afff79fdf3 Mon Sep 17 00:00:00 2001 From: Andreas Kemnade Date: Tue, 11 Mar 2025 08:51:19 +0900 Subject: [PATCH] ARM: dts: omap36xx: declare 1GHz OPP as turbo again BugLink: https://bugs.launchpad.net/bugs/2101915 commit 96a64e9730c2c76cfa5c510583a0fbf40d62886b upstream. Operating stable without reduced chip life at 1Ghz needs several technologies working: The technologies involve - SmartReflex - DVFS As this cannot directly specified in the OPP table as dependecies in the devicetree yet, use the turbo flag again to mark this OPP as something special to have some kind of opt-in. So revert commit 5f1bf7ae8481 ("ARM: dts: omap36xx: Remove turbo mode for 1GHz variants") Practical reasoning: At least the GTA04A5 (DM3730) has become unstable with that OPP enabled. Furthermore nothing enforces the availability of said technologies, even in the kernel configuration, so allow users to rather opt-in.
