From 6609dbe40e199ca8b1e99513d0e4bbc32b0d53b7 Mon Sep 17 00:00:00 2001 From: Peter De Schrijver Date: Tue, 17 Sep 2013 15:42:24 +0300 Subject: [PATCH] clk: tegra: move audio clk to common file Move audio clocks and PLLA initialization to a common file so it can be used by multiple Tegra SoCs. Also a new array tegra114_clks is introduced for Tegra114 which specifies which common clocks are available on Tegra114 and what their DT IDs are.
