From 343a607cb79259429afbb9820bf524d33084e66c Mon Sep 17 00:00:00 2001 From: Peter De Schrijver Date: Mon, 2 Sep 2013 15:22:02 +0300 Subject: [PATCH] clk: tegra: common periph_clk_enb_refcnt and clks This patch makes periph_clk_enb_refcnt a global array, dynamically allocated at boottime. It simplifies the macros somewhat and allows clocks common to several Tegra SoCs to be defined in a separate files. Also the clks array becomes global and dynamically allocated which allows the DT registration to be moved to a generic funcion.
