From mboxrd@z Thu Jan 1 00:00:00 1970 From: thomas.petazzoni@free-electrons.com (Thomas Petazzoni) Date: Mon, 19 Nov 2012 17:52:37 +0100 Subject: [PATCH 1/7] clk: mvebu: init all mvebu clock types from mvebu_clocks_init() In-Reply-To: <1353343963-23034-1-git-send-email-thomas.petazzoni@free-electrons.com> References: <1353343963-23034-1-git-send-email-thomas.petazzoni@free-electrons.com> Message-ID: <1353343963-23034-2-git-send-email-thomas.petazzoni@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The mvebu_clocks_init() function should register all the mvebu clock types, so that all mvebu platforms only have to call mvebu_clocks_init(). This fixes mach-mvebu because mvebu_clk_gating_init() was never called and therefore none of the gating clocks were registered. mach-kirkwood and mach-dove are updated to not call mvebu_clk_gating_init() a second time. Thanks to this, it is no longer necessary to expose mvebu_clk_gating_init() beyond the clock framework, so we get rid of its prototype in and we add it in a private drivers/clk/mvebu/clk-gating-ctrl.h header file.
