Subject: [PATCH 1/8] ARM: sun8i: Fix the mali clock rate
Date: Thu, 9 Feb 2017 17:39:15 +0100 [thread overview]
Message-ID: <4830ced34cc83058f7cad123be67fecc624a99d6.1486655917.git-series.maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <cover.7101c7323e6f22e281ad70b93488cf44caca4ca0.1486655917.git-series.maxime.ripard@free-electrons.com>
In-Reply-To: <cover.7101c7323e6f22e281ad70b93488cf44caca4ca0.1486655917.git-series.maxime.ripard@free-electrons.com>
The Mali clock rate was improperly assumed to be 408MHz, while it was
really 384Mhz, 408MHz being the "extreme" frequency, and definitely not
stable.
Switch for the stable, correct frequency for the GPU.
