From 00c674e42c278e7af7b39b6c72dbbaa5e7ebd96c Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 18 Nov 2013 16:11:35 +0100 Subject: [PATCH] clk: tegra: Fix clock rate computation The PLL output frequency is multiplied during the P-divider computation, so it needs to be divided by the P-divider again before returning. This fixes an issue where clk_round_rate() would return the multiplied frequency instead of the real one after the P-divider.
