From 2f924ac33f6bd46dcf1d1374401515ada5a35f21 Mon Sep 17 00:00:00 2001 From: Alex Frid Date: Tue, 25 Jul 2017 13:34:13 +0300 Subject: clk: tegra: Fix T210 PLLRE registration Switched Tegra210 PLLRE registration to common PLL ops instead of special PLLRE ops used on previous Tegra chips. The latter ops do not follow chip specific PLL frequency table, and do not apply chip specific rate calculation method. Removed unnecessary default rate setting that duplicates h/w reset state, and is overwritten by clock initialization, anyway.
