Subject: [PATCH] drm/amd/powerplay: add dpm force multiple levels on cz/tonga/fiji/polaris (v2)
Date: Mon,  2 May 2016 16:00:50 -0400	[thread overview]
Message-ID: <1462219259-29806-38-git-send-email-alexander.deucher@amd.com> (raw)
In-Reply-To: <1462219259-29806-1-git-send-email-alexander.deucher@amd.com>

From: Eric Huang <JinHuiEric.Huang@amd.com>

Allows you to force multiple levels rather than just one via the new
sysfs interrface.

v2: squash in:
drm/amd/powerplay: ensure clock level set by user is valid.
From Rex.
