This converts sunxi clock +providers to make use of it and get rid of the mach specific clk init +call. As sunxi has a bunch of independent clk provider nodes, we hook +current clock init to board compatible to make it called once. + +Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> +Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> +Acked-by: Mike Turquette <mturquette@linaro.org> +--- + arch/arm/mach-sunxi/sunxi.c | 4 +--- + drivers/clk/sunxi/clk-sunxi.c | 11 ++++++----- + include/linux/clk/sunxi.h | 22 ---------------------- + 3 files changed, 7 insertions(+), 30 deletions(-) + delete mode 100644 include/linux/clk/sunxi.h + +diff --git a/arch/arm/mach-sunxi/sunxi.c b/arch/arm/mach-sunxi/sunxi.c +index e79fb34..e5a6975 100644 +--- a/arch/arm/mach-sunxi/sunxi.c ++++ b/arch/arm/mach-sunxi/sunxi.c +@@ -20,8 +20,6 @@ + #include <linux/io.h> + #include <linux/reboot.h> + +-#include <linux/clk/sunxi.h> +- + #include <asm/mach/arch.h> + #include <asm/mach/map.h> + #include <asm/system_misc.h> +@@ -118,7 +116,7 @@ static void sunxi_setup_restart(void) + + static void __init sunxi_timer_init(void) + { +- sunxi_init_clocks(); ++ of_clk_init(NULL); + clocksource_of_init(); + } + +diff --git a/drivers/clk/sunxi/clk-sunxi.c b/drivers/clk/sunxi/clk-sunxi.c +index 34ee69f..9bbd035 100644 +--- a/drivers/clk/sunxi/clk-sunxi.c ++++ b/drivers/clk/sunxi/clk-sunxi.c +@@ -16,7 +16,6 @@ + + #include <linux/clk-provider.h> + #include <linux/clkdev.h> +-#include <linux/clk/sunxi.h> + #include <linux/of.h> + #include <linux/of_address.h> + +@@ -617,11 +616,8 @@ static void __init of_sunxi_table_clock_setup(const struct of_device_id *clk_mat + } + } + +-void __init sunxi_init_clocks(void) ++static void __init sunxi_init_clocks(struct device_node *np) + { +- /* Register all the simple and basic clocks on DT */ +- of_clk_init(NULL); +- + /* Register factor clocks */ + of_sunxi_table_clock_setup(clk_factors_match, sunxi_factors_clk_setup); + +@@ -634,3 +630,8 @@ void __init sunxi_init_clocks(void) + /* Register gate clocks */ + of_sunxi_table_clock_setup(clk_gates_match, sunxi_gates_clk_setup); + } ++CLK_OF_DECLARE(sun4i_a10_clk_init, "allwinner,sun4i-a10", sunxi_init_clocks); ++CLK_OF_DECLARE(sun5i_a10s_clk_init, "allwinner,sun5i-a10s", sunxi_init_clocks); ++CLK_OF_DECLARE(sun5i_a13_clk_init, "allwinner,sun5i-a13", sunxi_init_clocks); ++CLK_OF_DECLARE(sun6i_a31_clk_init, "allwinner,sun6i-a31", sunxi_init_clocks); ++CLK_OF_DECLARE(sun7i_a20_clk_init, "allwinner,sun7i-a20", sunxi_init_clocks); +diff --git a/include/linux/clk/sunxi.h b/include/linux/clk/sunxi.h +deleted file mode 100644 +index e074fdd..0000000 +--- a/include/linux/clk/sunxi.h ++++ /dev/null +@@ -1,22 +0,0 @@ +-/* +- * Copyright 2012 Maxime Ripard +- * +- * Maxime Ripard <maxime.ripard@free-electrons.com> +- * +- * This program is free software; you can redistribute it and/or modify +- * it under the terms of the GNU General Public License as published by +- * the Free Software Foundation; either version 2 of the License, or +- * (at your option) any later version. +- * +- * This program is distributed in the hope that it will be useful, +- * but WITHOUT ANY WARRANTY; without even the implied warranty of +- * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
