From ce910686f814fe220f4e55ecca5cfdea7082b3de Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 2 Apr 2013 16:18:44 +0200 Subject: [PATCH] clk: tegra: Make gr2d and gr3d clocks children of pll_c By default these clocks are children of pll_m, but in downstream kernels they are reparented to pll_c. While at it, decrease their frequencies to 300 MHz because the defaults aren't in the specified range. gr2d can reportedly run at much higher frequencies, but 300 MHz works and is a more conservative default.
