Subject: [PATCH v4 3/7] drm: msm: a6xx: set gpu freq through hfi
Date: Fri, 10 Jul 2020 01:30:23 +0530 [thread overview]
Message-ID: <1594324828-9571-4-git-send-email-akhilpo@codeaurora.org> (raw)
In-Reply-To: <1594324828-9571-1-git-send-email-akhilpo@codeaurora.org>
Newer targets support changing gpu frequency through HFI. So
use that wherever supported instead of the legacy method.
