From c96f598be7dd075bd0c6bda73b7819c1a6a2016a Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Tue, 26 Sep 2017 16:02:47 +0200 Subject: [PATCH] sunxi: clk: fix N formula for CPUX clocks As explained in arch/arm/mach-sunxi/clock_sun8i_a83t.c, clk for CPU clusters is computed as clk = 24*n. However, the current formula is clk = 24*(n-1). This results in a clock set to a frequency that isn't specified as possible for CPUs. Let's use the correct formula.
