From e098bc9612c2b60f94920461d71c92962a916e73 Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Thu, 13 Aug 2020 16:39:25 +0800 Subject: drm/amd/pm: optimize the power related source code layout The target is to provide a clear entry point(for power routines). Also this can help to maintain a clear view about the frameworks used on different ASICs. Hopefully all these can make power part more friendly to play with.
