From f6a09bace0bb9587985b48ed652f2b292f8de0de Mon Sep 17 00:00:00 2001 From: Eugeniy Paltsev Date: Mon, 14 Aug 2017 19:12:11 +0300 Subject: [PATCH] ARC: [plat-axs103] use clk driver #2: Add core pll node to DT to manage cpu clk Add core pll node (core_clk) to manage cpu frequency. core_clk represents pll itself. input_clk represents clock signal source (basically xtal) which comes to pll input.
